Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (May 1, 2012 to October 31, 2012).

Actual Expenses

The first line of the accompanying table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

Notes to Financial Statements

For the period ended October 31, 2012 (Unaudited)

(Amounts in thousands except percentages)

1. Organization.

Fidelity® Large Cap Stock Fund (the Fund) is a fund of Fidelity Commonwealth Trust (the Trust) and is authorized to issue an unlimited number of shares. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.

2. Investments in Fidelity Central Funds.

The Fund invests in Fidelity Central Funds, which are open-end investment companies available only to other investment companies and accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The Fund's Schedule of Investments lists each of the Fidelity Central Funds held as of period end, if any, as an investment of the Fund, but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of FMR.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) web site at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds are available on the SEC web site or upon request.

3. Significant Accounting Policies.

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. In accordance with valuation policies and procedures approved by the Board of Trustees (the Board), the Fund attempts to obtain prices from one or more third party pricing vendors or brokers to value its investments. When current market prices, quotations or rates are not readily available or reliable, securities will be fair valued in good faith by the FMR Fair Value Committee (the Committee), in accordance with procedures adopted by the Fund's Board. Factors used in determining fair value vary by security type and may include market or security specific events,

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

(Amounts in thousands except percentages)

3. Significant Accounting Policies - continued

Security Valuation - continued

changes in interest rates and credit quality. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees the Fund's valuation policies and procedures and is responsible for approving and reporting to the Board all fair value determinations.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows:

Equity securities, including restricted securities, for which market quotations are readily available, are valued at the last reported sale price or official closing price as reported by a third party pricing vendor on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. In the event there were no sales during the day or closing prices are not available, securities are valued at the last quoted bid price or may be valued using the last available price and are generally categorized as Level 2 in the hierarchy. For foreign equity securities, when significant market or security specific events arise, comparisons to the valuation of American Depositary Receipts (ADRs), futures contracts, Exchange-Traded Funds (ETFs) and certain indexes as well as quoted prices for similar securities are used and are categorized as Level 2 in the hierarchy. Utilizing these techniques may result in transfers between Level 1 and Level 2. For restricted equity securities and private placements where observable inputs are limited, assumptions about market activity and risk are used and these securities are generally categorized as Level 3 in the hierarchy.

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing vendors or from brokers who make markets in such securities. For corporate bonds, pricing vendors utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type as well as broker-supplied prices and are generally categorized as Level 2 in the hierarchy. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party

Security Valuation - continued

pricing vendors. These are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level, as of October 31, 2012, is included at the end of the Fund's Schedule of Investments.

Foreign Currency Translation. The Fund may use foreign currency contracts to facilitate transactions in foreign-denominated securities. Gains and losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts' terms.

Foreign-denominated assets, including investment securities, and liabilities are translated into U.S. dollars at the exchange rates at period end. Purchases and sales of investment securities, income and dividends received and expenses denominated in foreign currencies are translated into U.S. dollars at the exchange rate in effect on the transaction date.

The effects of exchange rate fluctuations on investments are included with the net realized and unrealized gain (loss) on investment securities. Other foreign currency transactions resulting in realized and unrealized gain (loss) are disclosed separately.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Fund is informed of the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The Fund estimates the components of distributions received that may be considered return of capital distributions or capital gain distributions. Interest income and distributions from the Fidelity Central Funds are

accrued as earned. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for income taxes is required. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. A fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction. Foreign taxes are provided for based on the Fund's understanding of the tax rules and rates that exist in the foreign markets in which it invests.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Book-tax differences are primarily due to futures transactions, foreign currency transactions, partnerships, equity-debt reclassifications, deferred trustee compensation, capital loss carryforwards and losses deferred due to wash sales and excise tax regulations.

The federal tax cost of investment securities and unrealized appreciation (depreciation) as of period end were as follows:

Capital loss carryforwards are only available to offset future capital gains of the Fund to the extent provided by regulations and may be limited. Under the Regulated Investment Company Modernization Act of 2010 (the Act), the Fund is permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period and such capital losses are required to be used prior to any losses that expire. At April 30, 2012, capital loss carryforwards were as follows:

Restricted Securities. The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of the Fund's Schedule of Investments.

New Accounting Pronouncement. In December 2011, the Financial Accounting Standards Board issued Accounting Standard Update No. 2011-11, Disclosures about Offsetting Assets and Liabilities . The update creates new disclosure requirements requiring entities to disclose both gross and net information for derivatives and other financial instruments that are either offset in the Statement of Assets and Liabilities or subject to an enforceable master netting arrangement or similar agreement. The disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. Management is currently evaluating the impact of the update's adoption on the Fund's financial statement disclosures.

4. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $515,880 and $286,130, respectively.

5. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .30% of the Fund's average net assets and an annualized group fee rate that averaged .26% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. In addition, the management fee is subject to a performance adjustment (up to a maximum of ± .20% of the Fund's average net assets over a 36 month performance period). The upward or downward adjustment to the management fee is based on the Fund's relative investment performance as compared to an appropriate benchmark index. For the period, the total annualized management fee rate, including the performance adjustment, was .59% of the Fund's average net assets.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of FMR, is the Fund's transfer, dividend disbursing and shareholder servicing agent. FIIOC receives account fees and asset-based fees that vary according to account size and type of account. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period, the transfer agent fees were equivalent to an annualized rate of .22% of average net assets.

Accounting and Security Lending Fees. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, maintains the Fund's accounting records. The accounting fee is based on the level of average net assets for each month. Under a separate contract, FSC administers the security lending program. The security lending fee is based on the number and duration of lending transactions.

Brokerage Commissions. The Fund placed a portion of its portfolio transactions with brokerage firms which are affiliates of the investment adviser. The commissions paid to these affiliated firms were $13 for the period.

6. Committed Line of Credit.

The Fund participates with other funds managed by FMR or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $1 and is reflected in Miscellaneous expenses on the Statement of Operations. During the period, there were no borrowings on this line of credit.

Semiannual Report

7. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. The value of loaned securities and cash collateral at period end are disclosed on the Fund's Statement of Assets and Liabilities. At period end, there were no security loans outstanding with FCM. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Total security lending income during the period amounted to $153, including $4 from securities loaned to FCM.

8. Expense Reductions.

Many of the brokers with whom FMR places trades on behalf of the Fund provided services to the Fund in addition to trade execution. These services included payments of certain expenses on behalf of the Fund totaling $6 for the period.

9. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Large Cap Stock Fund

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract and sub-advisory agreements (together, the Advisory Contracts) for the fund. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.

The Board meets regularly and, at each of its meetings, considers factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board has established various standing committees, each composed of and chaired by Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of the fund's Advisory Contracts. The Board also meets as needed to consider matters specifically related to the Board's annual consideration of the renewal of Advisory Contracts. Members of the Board may also meet with trustees of other Fidelity funds through ad hoc joint committees to discuss certain matters relevant to the Fidelity funds.

At its July 2012 meeting, the Board of Trustees, including the Independent Trustees, unanimously determined to renew the fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services to be provided to the fund and its shareholders (including the investment performance of the fund); (ii) the competitiveness of the fund's management fee and total expense ratio relative to peer funds; (iii) the total costs of the services to be provided by and the profits to be realized by Fidelity from its relationship with the fund; (iv) the extent to which economies of scale exist and would be realized as the fund grows; and (v) whether fee levels reflect these economies of scale, if any, for the benefit of fund shareholders.

In considering whether to renew the Advisory Contracts for the fund, the Board reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts is in the best interests of the fund and its shareholders and that the compensation payable under the Advisory Contracts is fair and reasonable. The Board's decision to renew the Advisory Contracts was not based on any single factor, but rather was based on a comprehensive consideration of all the information provided to the Board at its meetings throughout the year. The Board, in reaching its determination to renew the Advisory Contracts, is aware that shareholders in the fund have a broad range of investment choices available to them, including a wide choice among mutual funds offered by Fidelity's competitors, and that the fund's shareholders, who have the opportunity to review and weigh the disclosure provided by the fund in its prospectus and other public disclosures, have chosen to invest in this fund, managed by Fidelity.

Nature, Extent, and Quality of Services Provided. The Board considered the staffing within the investment adviser, FMR, and the sub-advisers (together, the Investment Advisers), including the backgrounds of the fund's investment personnel, and also considered the fund's investment objective, strategies, and related investment philosophy. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the portfolio manager compensation program and whether this structure provides appropriate incentives to act in the best interests of the fund.

Resources Dedicated to Investment Management and Support Services . The Board and the Fund Oversight and Research Committees reviewed the general qualifications and capabilities of the Investment Advisers' investment staff, including its size, education, experience, and resources, as well as the Investment Advisers' approach to recruiting, training, managing, and compensating investment personnel. The Board also noted that FMR has continued to increase the resources devoted to non-U.S. offices, including expansion of Fidelity's global investment organization. The Board noted that Fidelity's analysts have extensive resources, tools and capabilities that allow them to conduct sophisticated quantitative and fundamental analysis, as well as credit analysis of issuers, counterparties and guarantors. The Board also believes that Fidelity's investment professionals have sufficient access to global information and data so as to provide competitive investment results over time, and that those professionals also have access to sophisticated tools that permit them to assess portfolio construction and risk and performance attribution characteristics continuously, as well as to transmit new information and research conclusions rapidly around the world. Additionally, in its deliberations, the Board considered the Investment Advisers' trading and risk management capabilities and resources, which are an integral part of the investment management process.

Shareholder and Administrative Services . The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for the fund; (ii) the nature and extent of the supervision of third party service providers, principally custodians and subcustodians; and (iii) the resources devoted to, and the record of compliance with, the fund's compliance policies and procedures. The Board also reviewed the allocation of fund brokerage, including allocations to brokers affiliated with the Investment Advisers, the use of brokerage commissions to pay fund expenses, and the use of "soft" commission dollars to pay for research services.

Semiannual Report

The Board noted that the growth of fund assets over time across the complex allows Fidelity to reinvest in the development of services designed to enhance the value or convenience of the Fidelity funds as investment vehicles. These services include 24-hour access to account information and market information through telephone representatives and over the Internet, investor education materials and asset allocation tools, and the expanded availability of Fidelity Investor Centers.

Investment in a Large Fund Family . The Board considered the benefits to shareholders of investing in a Fidelity fund, including the benefits of investing in a fund that is part of a large family of funds offering a variety of investment disciplines and providing a large variety of mutual fund investor services. The Board noted that Fidelity had taken, or had made recommendations that resulted in the Fidelity funds taking, a number of actions over the previous year that benefited particular funds, including (i) continuing to dedicate additional resources to investment research and support of the senior management team that oversees asset management; (ii) persisting in efforts to enhance Fidelity's research capabilities, in particular, international research; (iii) launching new funds and making other enhancements to meet client needs for global and income-oriented solutions; (iv) continuing to launch dedicated lower cost underlying funds to meet investment management's portfolio construction needs related to expanding underlying fund options, specifically for the Freedom Fund product lines; (v) adopting a "Stock Selector" sector neutral investment approach and employing a team of portfolio managers who are sector specialists to manage certain funds; (vi) rationalizing product lines and gaining increased efficiencies through the mergers of several funds into other funds; (vii) strengthening the Spartan Index Fund product line by adding new funds and/or new low-cost institutional share classes, restructuring fund expenses to accommodate new classes, and reducing investment minimums for certain classes of shares; (viii) modifying the eligibility criteria for Institutional Class shares to increase their appeal to government entities and charitable investors; and (ix) reducing certain transfer agent fee rates.

Investment Performance . The Board considered whether the fund has operated in accordance with its investment objective, as well as its record of compliance with its investment restrictions. It also reviewed the fund's absolute investment performance, as well as the fund's relative investment performance measured over multiple periods against (i) a broad-based securities market index, and (ii) a peer group of mutual funds deemed appropriate by Fidelity and reviewed by the Board. The following charts considered by the Board show, over the one-, three-, and five-year periods ended December 31, 2011, the fund's cumulative total returns, the cumulative total returns of a broad-based securities market index ("benchmark"), and a range of cumulative total returns of a peer group of mutual funds identified by Morningstar, Inc. as having an investment style similar to that of the fund based on underlying portfolio holdings. The box within each chart shows the 25th percentile return (top of box) and the 75th percentile return (bottom of box) of the peer group. Returns shown above the box are in the first quartile and returns shown below the box are in the fourth quartile. The percentage beaten number noted below each chart corresponds to the percentile box and represents the percentage of funds in the peer group whose performance was equal to or lower than that of the fund.

Fidelity Large Cap Stock Fund

WSD180517

The Board reviewed the fund's relative investment performance against its peer group and noted that the performance of the fund was in the third quartile for the one-year period and the first quartile for the three- and five-year periods. The Board also noted that the investment performance of the fund compared favorably to its benchmark for the three- and five-year periods, although the fund's one-year total return was lower than its benchmark. The Board also reviewed the fund's performance since inception as well as performance in the current year.

The Board also considered that the fund's management fee is subject to upward or downward adjustment depending upon whether, and to what extent, the fund's investment performance for the performance period exceeds, or is exceeded by, the record (over the same period) of a Board-approved performance adjustment index. The Board noted that the performance adjustment provides FMR with a strong economic incentive to seek to achieve superior performance for the fund's shareholders and helps to more closely align the interests of FMR and the fund's shareholders.

Based on its review, the Board concluded that the nature, extent, and quality of services provided to the fund under the Advisory Contracts should benefit the fund's shareholders.

Semiannual Report

Competitiveness of Management Fee and Total Expense Ratio. The Board considered the fund's management fee and total expense ratio compared to "mapped groups" of competitive funds and classes. Fidelity creates "mapped groups" by combining similar Lipper investment objective categories that have comparable management fee characteristics. Combining Lipper investment objective categories aids the Board's management fee and total expense ratio comparisons by broadening the competitive group used for comparison and by reducing the number of universes to which various Fidelity funds are compared.

Management Fee . The Board considered two proprietary management fee comparisons for the 12-month periods shown in the chart below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group." The Total Mapped Group comparison focuses on a fund's standing relative to the total universe of comparable funds available to investors in terms of gross management fees before expense reimbursements or caps, and without giving effect to the fund's performance adjustment. "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than the fund's. For example, a TMG % of 10% means that 90% of the funds in the Total Mapped Group had higher management fees than the fund. The "Asset-Size Peer Group" (ASPG) comparison focuses on a fund's standing relative to non-Fidelity funds similar in size to the fund within the Total Mapped Group. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee characteristics, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which the fund's management fee ranked and the impact of the fund's performance adjustment, is also included in the chart and considered by the Board.

Fidelity Large Cap Stock Fund

The Board noted that the fund's management fee ranked below the median of its Total Mapped Group and below the median of its ASPG for 2011. The Board also noted the effect of the fund's positive performance adjustment on the fund's management fee ranking. The Board noted that the performance adjustment for each year represents calculations for performance periods that differ from the periods shown in the performance charts above.

Based on its review, the Board concluded that the fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered.

Total Expense Ratio . In its review of the fund's total expense ratio, the Board considered the fund's management fee as well as other fund expenses, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees. The Board also noted the effects of any waivers and reimbursements on fees and expenses, as well as the impact of the fund's performance adjustment. As part of its review, the Board also considered the current and historical total expense ratios of the fund compared to competitive fund median expenses. The fund is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure.

The Board noted that the fund's total expense ratio ranked below its competitive median for 2011.

Semiannual Report

Fees Charged to Other Fidelity Clients . The Board also considered Fidelity fee structures and other information with respect to clients of FMR and its affiliates, such as other mutual funds advised or subadvised by FMR or its affiliates, pension plan clients, and other institutional clients. The Board noted the findings of the 2010 ad hoc joint committee (created with the board of other Fidelity funds), which reviewed and compared Fidelity's institutional investment advisory business with its business of providing services to the Fidelity funds, including the differences in services provided, fees charged, and costs incurred, as well as competition in their respective marketplaces.

Based on its review of total expense ratios and fees charged to other Fidelity clients, the Board concluded that the fund's total expense ratio was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability.  The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and its shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

On an annual basis, FMR presents to the Board Fidelity's profitability for the fund. Fidelity calculates the profitability for each fund, as well as aggregate profitability for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the books and records of Fidelity on which Fidelity's audited financial statements are based. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies.

PricewaterhouseCoopers LLP (PwC), independent registered public accounting firm and auditor to Fidelity and certain Fidelity funds, has been engaged annually by the Board as part of the Board's assessment of Fidelity's profitability analysis. PwC's engagement includes the review and assessment of Fidelity's methodologies used in determining the revenues and expenses attributable to Fidelity's mutual fund business, and completion of agreed-upon procedures surrounding the mathematical accuracy of fund profitability and its conformity to allocation methodologies. After considering PwC's reports issued under the engagement and information provided by Fidelity, the Board concluded that while other allocation methods may also be reasonable, Fidelity's profitability methodologies are reasonable in all material respects.

The Board also reviewed Fidelity's non-fund businesses and fall-out benefits related to the mutual fund business as well as cases where Fidelity's affiliates may benefit from or be related to the fund's business.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of the fund and was satisfied that the profitability was not excessive in the circumstances.

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale through increased services to the fund, through waivers or reimbursements, or through fee or expense reductions. The Board also noted that in 2009, it and the board of other Fidelity funds created an ad hoc committee (the Economies of Scale Committee) to analyze whether FMR attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board recognized that the fund's management contract incorporates a "group fee" structure, which provides for lower group fee rates as total fund assets under FMR's management increase, and for higher group fee rates as total fund assets under FMR's management decrease. FMR calculates the group fee rates based on a tiered asset "breakpoint" schedule that varies based on asset class. The Board considered that the group fee is designed to deliver the benefits of economies of scale to fund shareholders when total Fidelity fund assets increase, even if assets of any particular fund are unchanged or have declined, because some portion of Fidelity's costs are attributable to services provided to all Fidelity funds, and all funds benefit if those costs can be allocated among more assets. The Board concluded that, given the group fee structure, fund shareholders will benefit from lower management fees as assets under FMR's management increase at the fund complex level, regardless of whether Fidelity achieves any such economies of scale.

The Board concluded, taking into account the analysis of the Economies of Scale Committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.

Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Fidelity funds' Advisory Contracts, the Board requested and received additional information on certain topics, including (i) fund performance trends, actions to be taken by FMR to improve certain funds' overall performance, and Fidelity's long-term strategies for certain funds; (ii) the potential to further rationalize the Fidelity fund lineup with the possibility of achieving savings for the funds and Fidelity; (iii) Fidelity's compensation structure for portfolio managers and other key investment personnel; (iv) the amount of the investment that each portfolio manager has made in the Fidelity fund(s) that he or she manages; (v) the realization of fall-out benefits in certain Fidelity business units; (vi) Fidelity's group fee structures, the potential impact of regulatory changes on such structures, and the rationale for the individual fee rates of certain funds; (vii) fund profitability methodology, including Fidelity's cost allocation methodology, and the impact of certain factors on fund profitability results; (viii) trends regarding industry use of performance fee structures and the possibility of implementing performance fee structures for additional funds; and (ix) the impact of net redemptions from the Fidelity funds.

Semiannual Report

Based on its evaluation of all of the conclusions noted above, and after considering all factors it believed relevant, the Board ultimately concluded that the advisory fee structures are fair and reasonable, and that the fund's Advisory Contracts should be renewed.

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (May 1, 2012 to October 31, 2012).

Actual Expenses

The first line of the accompanying table for each class of the Fund provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class of the Fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table for each class of the Fund provides information about hypothetical account values and hypothetical expenses based on a Class' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Class' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Notes to Financial Statements

For the period ended October 31, 2012 (Unaudited)

(Amounts in thousands except percentages)

1. Organization.

Fidelity® Mid-Cap Stock Fund (the Fund) is a fund of Fidelity Commonwealth Trust (the Trust) and is authorized to issue an unlimited number of shares. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund offers Mid-Cap Stock and Class K shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Investment income, realized and unrealized capital gains and losses, the common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated on a pro-rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent fees incurred. Certain expense reductions may also differ by class.

2. Investments in Fidelity Central Funds.

The Fund invests in Fidelity Central Funds, which are open-end investment companies available only to other investment companies and accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The Fund's Schedule of Investments lists each of the Fidelity Central Funds held as of period end, if any, as an investment of the Fund, but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of FMR.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) web site at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds are available on the SEC web site or upon request.

3. Significant Accounting Policies.

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the Fund:

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

(Amounts in thousands except percentages)

3. Significant Accounting Policies - continued

Security Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. In accordance with valuation policies and procedures approved by the Board of Trustees (the Board), the Fund attempts to obtain prices from one or more third party pricing vendors or brokers to value its investments. When current market prices, quotations or rates are not readily available or reliable, securities will be fair valued in good faith by the FMR Fair Value Committee (the Committee), in accordance with procedures adopted by the Fund's Board. Factors used in determining fair value vary by security type and may include market or security specific events. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees the Fund's valuation policies and procedures and is responsible for approving and reporting to the Board all fair value determinations.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows:

Equity securities, including restricted securities, for which market quotations are readily available, are valued at the last reported sale price or official closing price as reported by a third party pricing vendor on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. In the event there were no sales during the day or closing prices are not available, securities are valued at the last quoted bid price or may be valued using the last available price and are generally categorized as Level 2 in the hierarchy. For foreign equity securities, when significant market or security specific events arise, comparisons to the valuation of American Depositary Receipts (ADRs), futures contracts, Exchange-Traded Funds (ETFs) and certain indexes as well as quoted prices for similar securities are used and are categorized as Level 2 in the hierarchy. Utilizing these techniques may result in transfers between Level 1 and Level 2. For restricted equity securities and private placements where observable inputs are limited, assumptions about market activity and risk are used and these securities are generally categorized as Level 3 in the hierarchy.

Semiannual Report

3. Significant Accounting Policies - continued

Security Valuation - continued

Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level, as of October 31, 2012, including information on transfers between Levels 1 and 2, is included at the end of the Fund's Schedule of Investments.

Foreign Currency Translation. The Fund may use foreign currency contracts to facilitate transactions in foreign-denominated securities. Gains and losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts' terms.

Foreign-denominated assets, including investment securities, and liabilities are translated into U.S. dollars at the exchange rates at period end. Purchases and sales of investment securities, income and dividends received and expenses denominated in foreign currencies are translated into U.S. dollars at the exchange rate in effect on the transaction date.

The effects of exchange rate fluctuations on investments are included with the net realized and unrealized gain (loss) on investment securities. Other foreign currency transactions resulting in realized and unrealized gain (loss) are disclosed separately.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and net asset value (NAV) include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Fund is informed of the ex-dividend date. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The Fund estimates the components of distributions received that may be considered return of capital distributions or capital gain distributions. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Interest income and distributions from the Fidelity Central Funds are accrued as earned. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Deferred Trustee Compensation. Under a Deferred Compensation Plan (the Plan), independent Trustees may elect to defer receipt of a portion of their annual compensation. Deferred amounts are invested in a cross-section of Fidelity funds, are marked-to-market and remain in the Fund until distributed in accordance with the Plan. The investment of deferred amounts and the offsetting payable to the Trustees are included in the accompanying Statement of Assets and Liabilities.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for income taxes is required. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. A fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction. Foreign taxes are provided for based on the Fund's understanding of the tax rules and rates that exist in the foreign markets in which it invests.

Distributions are declared and recorded on the ex-dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Book-tax differences are primarily due to foreign currency transactions, partnerships, deferred trustees compensation and losses deferred due to wash sales and excise tax regulations.

Short-Term Trading (Redemption) Fees. Shares held by investors in the Fund less than 30 days are subject to a redemption fee equal to .75% of the net asset value of shares redeemed. All redemption fees, which reduce the proceeds of the shareholder redemption, are retained by the Fund and accounted for as an addition to paid in capital.

Restricted Securities. The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of the Fund's Schedule of Investments.

New Accounting Pronouncement. In December 2011, the Financial Accounting Standards Board issued Accounting Standard Update No. 2011-11, Disclosures about Offsetting Assets and Liabilities . The update creates new disclosure requirements requiring entities to disclose both gross and net information for derivatives and other financial instruments that are either offset in the Statement of Assets and Liabilities or subject to an enforceable master netting arrangement or similar agreement. The disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. Management is currently evaluating the impact of the update's adoption on the Fund's financial statement disclosures.

5. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .30% of the Fund's average net assets and an annualized group fee rate that averaged .26% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. In addition, the management fee is subject to a performance adjustment (up to a maximum of ± .20% of the Fund's average net assets over a 36 month performance period). The upward or downward adjustment to the management fee is based on the relative investment performance of Mid-Cap Stock as compared to an appropriate benchmark index. For the period, the total annualized management fee rate, including the performance adjustment, was .50% of the Fund's average net assets.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of FMR, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of Mid-Cap Stock. FIIOC receives an asset-based fee of Class K's average net assets. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period, transfer agent fees for each class were as follows:

Accounting and Security Lending Fees. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, maintains the Fund's accounting records. The accounting fee is based on the level of average net assets for each month. Under a separate contract, FSC administers the security lending program. The security lending fee is based on the number and duration of lending transactions .

Brokerage Commissions. The Fund placed a portion of its portfolio transactions with brokerage firms which are affiliates of the investment adviser. The commissions paid to these affiliated firms were $20 for the period.

6. Committed Line of Credit.

The Fund participates with other funds managed by FMR or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $8 and is reflected in Miscellaneous expenses on the Statement of Operations. During the period, there were no borrowings on this line of credit.

7. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. The value of loaned securities and cash collateral at period end are disclosed on the Fund's Statement of Assets and Liabilities. The value of securities loaned to FCM at period end was $7,477. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Total security lending income during the period amounted to $480, including $39 from securities loaned to FCM.

8. Expense Reductions.

Many of the brokers with whom FMR places trades on behalf of the Fund provided services to the Fund in addition to trade execution. These services included payments of certain expenses on behalf of the Fund totaling $136 for the period. In addition, through arrangements with the Fund's custodian, credits realized as a result of uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's custody expenses by forty-one dollars.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Mid-Cap Stock Fund

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract and sub-advisory agreements (together, the Advisory Contracts) for the fund. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.

The Board meets regularly and, at each of its meetings, considers factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board has established various standing committees, each composed of and chaired by Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of the fund's Advisory Contracts. The Board also meets as needed to consider matters specifically related to the Board's annual consideration of the renewal of Advisory Contracts. Members of the Board may also meet with trustees of other Fidelity funds through ad hoc joint committees to discuss certain matters relevant to the Fidelity funds.

At its July 2012 meeting, the Board of Trustees, including the Independent Trustees, unanimously determined to renew the fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services to be provided to the fund and its shareholders (including the investment performance of the fund); (ii) the competitiveness of the fund's management fee and total expense ratio relative to peer funds; (iii) the total costs of the services to be provided by and the profits to be realized by Fidelity from its relationship with the fund; (iv) the extent to which economies of scale exist and would be realized as the fund grows; and (v) whether fee levels reflect these economies of scale, if any, for the benefit of fund shareholders.

In considering whether to renew the Advisory Contracts for the fund, the Board reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts is in the best interests of the fund and its shareholders and that the compensation payable under the Advisory Contracts is fair and reasonable. The Board's decision to renew the Advisory Contracts was not based on any single factor, but rather was based on a comprehensive consideration of all the information provided to the Board at its meetings throughout the year. The Board, in reaching its determination to renew the Advisory Contracts, is aware that shareholders in the fund have a broad range of investment choices available to them, including a wide choice among mutual funds offered by Fidelity's competitors, and that the fund's shareholders, who have the opportunity to review and weigh the disclosure provided by the fund in its prospectus and other public disclosures, have chosen to invest in this fund, managed by Fidelity.

Semiannual Report

Nature, Extent, and Quality of Services Provided. The Board considered the staffing within the investment adviser, FMR, and the sub-advisers (together, the Investment Advisers), including the backgrounds of the fund's investment personnel, and also considered the fund's investment objective, strategies, and related investment philosophy. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the portfolio manager compensation program and whether this structure provides appropriate incentives to act in the best interests of the fund.

Resources Dedicated to Investment Management and Support Services . The Board and the Fund Oversight and Research Committees reviewed the general qualifications and capabilities of the Investment Advisers' investment staff, including its size, education, experience, and resources, as well as the Investment Advisers' approach to recruiting, training, managing, and compensating investment personnel. The Board also noted that FMR has continued to increase the resources devoted to non-U.S. offices, including expansion of Fidelity's global investment organization. The Board noted that Fidelity's analysts have extensive resources, tools and capabilities that allow them to conduct sophisticated quantitative and fundamental analysis, as well as credit analysis of issuers, counterparties and guarantors. The Board also believes that Fidelity's investment professionals have sufficient access to global information and data so as to provide competitive investment results over time, and that those professionals also have access to sophisticated tools that permit them to assess portfolio construction and risk and performance attribution characteristics continuously, as well as to transmit new information and research conclusions rapidly around the world. Additionally, in its deliberations, the Board considered the Investment Advisers' trading and risk management capabilities and resources, which are an integral part of the investment management process.

Shareholder and Administrative Services . The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for the fund; (ii) the nature and extent of the supervision of third party service providers, principally custodians and subcustodians; and (iii) the resources devoted to, and the record of compliance with, the fund's compliance policies and procedures. The Board also reviewed the allocation of fund brokerage, including allocations to brokers affiliated with the Investment Advisers, the use of brokerage commissions to pay fund expenses, and the use of "soft" commission dollars to pay for research services.

Semiannual Report

Board Approval of Investment Advisory Contracts and
Management Fees - continued

The Board noted that the growth of fund assets over time across the complex allows Fidelity to reinvest in the development of services designed to enhance the value or convenience of the Fidelity funds as investment vehicles. These services include 24-hour access to account information and market information through telephone representatives and over the Internet, investor education materials and asset allocation tools, and the expanded availability of Fidelity Investor Centers.

Investment in a Large Fund Family . The Board considered the benefits to shareholders of investing in a Fidelity fund, including the benefits of investing in a fund that is part of a large family of funds offering a variety of investment disciplines and providing a large variety of mutual fund investor services. The Board noted that Fidelity had taken, or had made recommendations that resulted in the Fidelity funds taking, a number of actions over the previous year that benefited particular funds, including (i) continuing to dedicate additional resources to investment research and support of the senior management team that oversees asset management; (ii) persisting in efforts to enhance Fidelity's research capabilities, in particular, international research; (iii) launching new funds and making other enhancements to meet client needs for global and income-oriented solutions; (iv) continuing to launch dedicated lower cost underlying funds to meet investment management's portfolio construction needs related to expanding underlying fund options, specifically for the Freedom Fund product lines; (v) adopting a "Stock Selector" sector neutral investment approach and employing a team of portfolio managers who are sector specialists to manage certain funds; (vi) rationalizing product lines and gaining increased efficiencies through the mergers of several funds into other funds; (vii) strengthening the Spartan Index Fund product line by adding new funds and/or new low-cost institutional share classes, restructuring fund expenses to accommodate new classes, and reducing investment minimums for certain classes of shares; (viii) modifying the eligibility criteria for Institutional Class shares to increase their appeal to government entities and charitable investors; and (ix) reducing certain transfer agent fee rates.

Investment Performance . The Board considered whether the fund has operated in accordance with its investment objective, as well as its record of compliance with its investment restrictions. It also reviewed the fund's absolute investment performance for each class, as well as the fund's relative investment performance for each class measured over multiple periods against (i) a broad-based securities market index, and (ii) a peer group of mutual funds deemed appropriate by Fidelity and reviewed by the Board. The following charts considered by the Board show, over the one-, three-, and five-year periods ended December 31, 2011, as available, the cumulative total returns of Class K and the retail class of the fund, the cumulative total returns of a broad-based securities market index ("benchmark"), and a range of cumulative total returns of a peer group of mutual funds identified by Morningstar, Inc. as having an investment style similar to that of the fund based on underlying portfolio holdings. The box within each chart shows the 25th percentile return (top of box) and the 75th percentile return (bottom of box) of the peer group. Returns shown above the box are in the first quartile and returns shown below the box are in the fourth quartile. The percentage beaten numbers noted below each chart correspond to the percentile box and represent the percentage of funds in the peer group whose performance was equal to or lower than that of the class indicated.

Semiannual Report

Fidelity Mid-Cap Stock Fund

WSD180540

The Board reviewed the fund's relative investment performance against its peer group and noted that the performance of the retail class of the fund (the class with the longer performance record) was in the second quartile for the one- and five-year periods and the first quartile for the three-year period. The Board also noted that the investment performance of the fund was lower than its benchmark for the one- and five-year periods, although the three-year cumulative total return of the retail class compared favorably to its benchmark. The Board considered that the variations in performance between the fund's classes reflect the variations in class expenses, which result in lower performance for the higher expense class. The Board also reviewed the fund's performance since inception as well as performance in the current year.

The Board also considered that the fund's management fee is subject to upward or downward adjustment depending upon whether, and to what extent, the fund's investment performance for the performance period exceeds, or is exceeded by, the record (over the same period) of a Board-approved performance adjustment index. The Board noted that the performance adjustment provides FMR with a strong economic incentive to seek to achieve superior performance for the fund's shareholders and helps to more closely align the interests of FMR and the fund's shareholders.

Semiannual Report

Board Approval of Investment Advisory Contracts and
Management Fees - continued

Based on its review, the Board concluded that the nature, extent, and quality of services provided to the fund under the Advisory Contracts should benefit the fund's shareholders.

Competitiveness of Management Fee and Total Expense Ratio. The Board considered the fund's management fee and total expense ratio compared to "mapped groups" of competitive funds and classes. Fidelity creates "mapped groups" by combining similar Lipper investment objective categories that have comparable management fee characteristics. Combining Lipper investment objective categories aids the Board's management fee and total expense ratio comparisons by broadening the competitive group used for comparison and by reducing the number of universes to which various Fidelity funds are compared.

Management Fee . The Board considered two proprietary management fee comparisons for the 12-month periods shown in the chart below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group." The Total Mapped Group comparison focuses on a fund's standing relative to the total universe of comparable funds available to investors in terms of gross management fees before expense reimbursements or caps, and without giving effect to the fund's performance adjustment. "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than the fund's. For example, a TMG % of 10% means that 90% of the funds in the Total Mapped Group had higher management fees than the fund. The "Asset-Size Peer Group" (ASPG) comparison focuses on a fund's standing relative to non-Fidelity funds similar in size to the fund within the Total Mapped Group. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee characteristics, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which the fund's management fee ranked and the impact of the fund's performance adjustment, is also included in the chart and considered by the Board.

Semiannual Report

Fidelity Mid-Cap Stock Fund

WSD180542

The Board noted that the fund's management fee ranked below the median of its Total Mapped Group and below the median of its ASPG for 2011. The Board also noted the effect of the fund's negative performance adjustment on the fund's management fee ranking. The Board noted that the performance adjustment for each year represents calculations for performance periods that differ from the periods shown in the performance charts above.

Based on its review, the Board concluded that the fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered.

Total Expense Ratio . In its review of each class's total expense ratio, the Board considered the fund's management fee as well as other fund or class expenses, as applicable, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees. The Board also noted the effects of any waivers and reimbursements on fees and expenses, as well as the impact of the fund's performance adjustment. As part of its review, the Board also considered the current and historical total expense ratios of each class of the fund compared to competitive fund median expenses. Each class of the fund is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure.

The Board noted that the total expense ratio of each class ranked below its competitive median for 2011.

Fees Charged to Other Fidelity Clients . The Board also considered Fidelity fee structures and other information with respect to clients of FMR and its affiliates, such as other mutual funds advised or subadvised by FMR or its affiliates, pension plan clients, and other institutional clients. The Board noted the findings of the 2010 ad hoc joint committee (created with the board of other Fidelity funds), which reviewed and compared Fidelity's institutional investment advisory business with its business of providing services to the Fidelity funds, including the differences in services provided, fees charged, and costs incurred, as well as competition in their respective marketplaces.

Semiannual Report

Board Approval of Investment Advisory Contracts and
Management Fees - continued

Based on its review of total expense ratios and fees charged to other Fidelity clients, the Board concluded that the total expense ratio of each class of the fund was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability.  The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and its shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

On an annual basis, FMR presents to the Board Fidelity's profitability for the fund. Fidelity calculates the profitability for each fund, as well as aggregate profitability for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the books and records of Fidelity on which Fidelity's audited financial statements are based. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies.

PricewaterhouseCoopers LLP (PwC), independent registered public accounting firm and auditor to Fidelity and certain Fidelity funds, has been engaged annually by the Board as part of the Board's assessment of Fidelity's profitability analysis. PwC's engagement includes the review and assessment of Fidelity's methodologies used in determining the revenues and expenses attributable to Fidelity's mutual fund business, and completion of agreed-upon procedures surrounding the mathematical accuracy of fund profitability and its conformity to allocation methodologies. After considering PwC's reports issued under the engagement and information provided by Fidelity, the Board concluded that while other allocation methods may also be reasonable, Fidelity's profitability methodologies are reasonable in all material respects.

The Board also reviewed Fidelity's non-fund businesses and fall-out benefits related to the mutual fund business as well as cases where Fidelity's affiliates may benefit from or be related to the fund's business.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of the fund and was satisfied that the profitability was not excessive in the circumstances.

Semiannual Report

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale through increased services to the fund, through waivers or reimbursements, or through fee or expense reductions. The Board also noted that in 2009, it and the board of other Fidelity funds created an ad hoc committee (the Economies of Scale Committee) to analyze whether FMR attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board recognized that the fund's management contract incorporates a "group fee" structure, which provides for lower group fee rates as total fund assets under FMR's management increase, and for higher group fee rates as total fund assets under FMR's management decrease. FMR calculates the group fee rates based on a tiered asset "breakpoint" schedule that varies based on asset class. The Board considered that the group fee is designed to deliver the benefits of economies of scale to fund shareholders when total Fidelity fund assets increase, even if assets of any particular fund are unchanged or have declined, because some portion of Fidelity's costs are attributable to services provided to all Fidelity funds, and all funds benefit if those costs can be allocated among more assets. The Board concluded that, given the group fee structure, fund shareholders will benefit from lower management fees as assets under FMR's management increase at the fund complex level, regardless of whether Fidelity achieves any such economies of scale.

The Board concluded, taking into account the analysis of the Economies of Scale Committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.

Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Fidelity funds' Advisory Contracts, the Board requested and received additional information on certain topics, including (i) fund performance trends, actions to be taken by FMR to improve certain funds' overall performance, and Fidelity's long-term strategies for certain funds; (ii) the potential to further rationalize the Fidelity fund lineup with the possibility of achieving savings for the funds and Fidelity; (iii) Fidelity's compensation structure for portfolio managers and other key investment personnel; (iv) the amount of the investment that each portfolio manager has made in the Fidelity fund(s) that he or she manages; (v) the realization of fall-out benefits in certain Fidelity business units; (vi) Fidelity's group fee structures, the potential impact of regulatory changes on such structures, and the rationale for the individual fee rates of certain funds; (vii) fund profitability methodology, including Fidelity's cost allocation methodology, and the impact of certain factors on fund profitability results; (viii) trends regarding industry use of performance fee structures and the possibility of implementing performance fee structures for additional funds; and (ix) the impact of net redemptions from the Fidelity funds.

Based on its evaluation of all of the conclusions noted above, and after considering all factors it believed relevant, the Board ultimately concluded that the advisory fee structures are fair and reasonable, and that the fund's Advisory Contracts should be renewed.

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (May 1, 2012 to October 31, 2012).

Actual Expenses

The first line of the accompanying table for each class of the Fund provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class of the Fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table for each class of the Fund provides information about hypothetical account values and hypothetical expenses based on a Class' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Class' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Notes to Financial Statements

For the period ended October 31, 2012 (Unaudited)

(Amounts in thousands except percentages)

1. Organization.

Fidelity® Mid-Cap Stock Fund (the Fund) is a fund of Fidelity Commonwealth Trust (the Trust) and is authorized to issue an unlimited number of shares. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund offers Mid-Cap Stock and Class K shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Investment income, realized and unrealized capital gains and losses, the common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated on a pro-rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent fees incurred. Certain expense reductions may also differ by class.

2. Investments in Fidelity Central Funds.

The Fund invests in Fidelity Central Funds, which are open-end investment companies available only to other investment companies and accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The Fund's Schedule of Investments lists each of the Fidelity Central Funds held as of period end, if any, as an investment of the Fund, but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of FMR.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) web site at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds are available on the SEC web site or upon request.

3. Significant Accounting Policies.

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the Fund:

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

(Amounts in thousands except percentages)

3. Significant Accounting Policies - continued

Security Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. In accordance with valuation policies and procedures approved by the Board of Trustees (the Board), the Fund attempts to obtain prices from one or more third party pricing vendors or brokers to value its investments. When current market prices, quotations or rates are not readily available or reliable, securities will be fair valued in good faith by the FMR Fair Value Committee (the Committee), in accordance with procedures adopted by the Fund's Board. Factors used in determining fair value vary by security type and may include market or security specific events. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees the Fund's valuation policies and procedures and is responsible for approving and reporting to the Board all fair value determinations.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows:

Equity securities, including restricted securities, for which market quotations are readily available, are valued at the last reported sale price or official closing price as reported by a third party pricing vendor on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. In the event there were no sales during the day or closing prices are not available, securities are valued at the last quoted bid price or may be valued using the last available price and are generally categorized as Level 2 in the hierarchy. For foreign equity securities, when significant market or security specific events arise, comparisons to the valuation of American Depositary Receipts (ADRs), futures contracts, Exchange-Traded Funds (ETFs) and certain indexes as well as quoted prices for similar securities are used and are categorized as Level 2 in the hierarchy. Utilizing these techniques may result in transfers between Level 1 and Level 2. For restricted equity securities and private placements where observable inputs are limited, assumptions about market activity and risk are used and these securities are generally categorized as Level 3 in the hierarchy.

Semiannual Report

3. Significant Accounting Policies - continued

Security Valuation - continued

Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level, as of October 31, 2012, including information on transfers between Levels 1 and 2, is included at the end of the Fund's Schedule of Investments.

Foreign Currency Translation. The Fund may use foreign currency contracts to facilitate transactions in foreign-denominated securities. Gains and losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts' terms.

Foreign-denominated assets, including investment securities, and liabilities are translated into U.S. dollars at the exchange rates at period end. Purchases and sales of investment securities, income and dividends received and expenses denominated in foreign currencies are translated into U.S. dollars at the exchange rate in effect on the transaction date.

The effects of exchange rate fluctuations on investments are included with the net realized and unrealized gain (loss) on investment securities. Other foreign currency transactions resulting in realized and unrealized gain (loss) are disclosed separately.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and net asset value (NAV) include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Fund is informed of the ex-dividend date. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The Fund estimates the components of distributions received that may be considered return of capital distributions or capital gain distributions. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Interest income and distributions from the Fidelity Central Funds are accrued as earned. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Deferred Trustee Compensation. Under a Deferred Compensation Plan (the Plan), independent Trustees may elect to defer receipt of a portion of their annual compensation. Deferred amounts are invested in a cross-section of Fidelity funds, are marked-to-market and remain in the Fund until distributed in accordance with the Plan. The investment of deferred amounts and the offsetting payable to the Trustees are included in the accompanying Statement of Assets and Liabilities.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for income taxes is required. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. A fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction. Foreign taxes are provided for based on the Fund's understanding of the tax rules and rates that exist in the foreign markets in which it invests.

Distributions are declared and recorded on the ex-dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Book-tax differences are primarily due to foreign currency transactions, partnerships, deferred trustees compensation and losses deferred due to wash sales and excise tax regulations.

Short-Term Trading (Redemption) Fees. Shares held by investors in the Fund less than 30 days are subject to a redemption fee equal to .75% of the net asset value of shares redeemed. All redemption fees, which reduce the proceeds of the shareholder redemption, are retained by the Fund and accounted for as an addition to paid in capital.

Restricted Securities. The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of the Fund's Schedule of Investments.

New Accounting Pronouncement. In December 2011, the Financial Accounting Standards Board issued Accounting Standard Update No. 2011-11, Disclosures about Offsetting Assets and Liabilities . The update creates new disclosure requirements requiring entities to disclose both gross and net information for derivatives and other financial instruments that are either offset in the Statement of Assets and Liabilities or subject to an enforceable master netting arrangement or similar agreement. The disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. Management is currently evaluating the impact of the update's adoption on the Fund's financial statement disclosures.

4. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $1,182,692 and $1,832,226, respectively.

5. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .30% of the Fund's average net assets and an annualized group fee rate that averaged .26% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. In addition, the management fee is subject to a performance adjustment (up to a maximum of ± .20% of the Fund's average net assets over a 36 month performance period). The upward or downward adjustment to the management fee is based on the relative investment performance of Mid-Cap Stock as compared to an appropriate benchmark index. For the period, the total annualized management fee rate, including the performance adjustment, was .50% of the Fund's average net assets.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of FMR, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of Mid-Cap Stock. FIIOC receives an asset-based fee of Class K's average net assets. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period, transfer agent fees for each class were as follows:

Accounting and Security Lending Fees. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, maintains the Fund's accounting records. The accounting fee is based on the level of average net assets for each month. Under a separate contract, FSC administers the security lending program. The security lending fee is based on the number and duration of lending transactions .

Brokerage Commissions. The Fund placed a portion of its portfolio transactions with brokerage firms which are affiliates of the investment adviser. The commissions paid to these affiliated firms were $20 for the period.

Semiannual Report

6. Committed Line of Credit.

The Fund participates with other funds managed by FMR or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $8 and is reflected in Miscellaneous expenses on the Statement of Operations. During the period, there were no borrowings on this line of credit.

7. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. The value of loaned securities and cash collateral at period end are disclosed on the Fund's Statement of Assets and Liabilities. The value of securities loaned to FCM at period end was $7,477. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Total security lending income during the period amounted to $480, including $39 from securities loaned to FCM.

8. Expense Reductions.

Many of the brokers with whom FMR places trades on behalf of the Fund provided services to the Fund in addition to trade execution. These services included payments of certain expenses on behalf of the Fund totaling $136 for the period. In addition, through arrangements with the Fund's custodian, credits realized as a result of uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's custody expenses by forty-one dollars.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Mid-Cap Stock Fund

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract and sub-advisory agreements (together, the Advisory Contracts) for the fund. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.

The Board meets regularly and, at each of its meetings, considers factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board has established various standing committees, each composed of and chaired by Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of the fund's Advisory Contracts. The Board also meets as needed to consider matters specifically related to the Board's annual consideration of the renewal of Advisory Contracts. Members of the Board may also meet with trustees of other Fidelity funds through ad hoc joint committees to discuss certain matters relevant to the Fidelity funds.

At its July 2012 meeting, the Board of Trustees, including the Independent Trustees, unanimously determined to renew the fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services to be provided to the fund and its shareholders (including the investment performance of the fund); (ii) the competitiveness of the fund's management fee and total expense ratio relative to peer funds; (iii) the total costs of the services to be provided by and the profits to be realized by Fidelity from its relationship with the fund; (iv) the extent to which economies of scale exist and would be realized as the fund grows; and (v) whether fee levels reflect these economies of scale, if any, for the benefit of fund shareholders.

In considering whether to renew the Advisory Contracts for the fund, the Board reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts is in the best interests of the fund and its shareholders and that the compensation payable under the Advisory Contracts is fair and reasonable. The Board's decision to renew the Advisory Contracts was not based on any single factor, but rather was based on a comprehensive consideration of all the information provided to the Board at its meetings throughout the year. The Board, in reaching its determination to renew the Advisory Contracts, is aware that shareholders in the fund have a broad range of investment choices available to them, including a wide choice among mutual funds offered by Fidelity's competitors, and that the fund's shareholders, who have the opportunity to review and weigh the disclosure provided by the fund in its prospectus and other public disclosures, have chosen to invest in this fund, managed by Fidelity.

Semiannual Report

Nature, Extent, and Quality of Services Provided. The Board considered the staffing within the investment adviser, FMR, and the sub-advisers (together, the Investment Advisers), including the backgrounds of the fund's investment personnel, and also considered the fund's investment objective, strategies, and related investment philosophy. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the portfolio manager compensation program and whether this structure provides appropriate incentives to act in the best interests of the fund.

Resources Dedicated to Investment Management and Support Services . The Board and the Fund Oversight and Research Committees reviewed the general qualifications and capabilities of the Investment Advisers' investment staff, including its size, education, experience, and resources, as well as the Investment Advisers' approach to recruiting, training, managing, and compensating investment personnel. The Board also noted that FMR has continued to increase the resources devoted to non-U.S. offices, including expansion of Fidelity's global investment organization. The Board noted that Fidelity's analysts have extensive resources, tools and capabilities that allow them to conduct sophisticated quantitative and fundamental analysis, as well as credit analysis of issuers, counterparties and guarantors. The Board also believes that Fidelity's investment professionals have sufficient access to global information and data so as to provide competitive investment results over time, and that those professionals also have access to sophisticated tools that permit them to assess portfolio construction and risk and performance attribution characteristics continuously, as well as to transmit new information and research conclusions rapidly around the world. Additionally, in its deliberations, the Board considered the Investment Advisers' trading and risk management capabilities and resources, which are an integral part of the investment management process.

Shareholder and Administrative Services . The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for the fund; (ii) the nature and extent of the supervision of third party service providers, principally custodians and subcustodians; and (iii) the resources devoted to, and the record of compliance with, the fund's compliance policies and procedures. The Board also reviewed the allocation of fund brokerage, including allocations to brokers affiliated with the Investment Advisers, the use of brokerage commissions to pay fund expenses, and the use of "soft" commission dollars to pay for research services.

Semiannual Report

Board Approval of Investment Advisory Contracts and
Management Fees - continued

The Board noted that the growth of fund assets over time across the complex allows Fidelity to reinvest in the development of services designed to enhance the value or convenience of the Fidelity funds as investment vehicles. These services include 24-hour access to account information and market information through telephone representatives and over the Internet, investor education materials and asset allocation tools, and the expanded availability of Fidelity Investor Centers.

Investment in a Large Fund Family . The Board considered the benefits to shareholders of investing in a Fidelity fund, including the benefits of investing in a fund that is part of a large family of funds offering a variety of investment disciplines and providing a large variety of mutual fund investor services. The Board noted that Fidelity had taken, or had made recommendations that resulted in the Fidelity funds taking, a number of actions over the previous year that benefited particular funds, including (i) continuing to dedicate additional resources to investment research and support of the senior management team that oversees asset management; (ii) persisting in efforts to enhance Fidelity's research capabilities, in particular, international research; (iii) launching new funds and making other enhancements to meet client needs for global and income-oriented solutions; (iv) continuing to launch dedicated lower cost underlying funds to meet investment management's portfolio construction needs related to expanding underlying fund options, specifically for the Freedom Fund product lines; (v) adopting a "Stock Selector" sector neutral investment approach and employing a team of portfolio managers who are sector specialists to manage certain funds; (vi) rationalizing product lines and gaining increased efficiencies through the mergers of several funds into other funds; (vii) strengthening the Spartan Index Fund product line by adding new funds and/or new low-cost institutional share classes, restructuring fund expenses to accommodate new classes, and reducing investment minimums for certain classes of shares; (viii) modifying the eligibility criteria for Institutional Class shares to increase their appeal to government entities and charitable investors; and (ix) reducing certain transfer agent fee rates.

Investment Performance . The Board considered whether the fund has operated in accordance with its investment objective, as well as its record of compliance with its investment restrictions. It also reviewed the fund's absolute investment performance for each class, as well as the fund's relative investment performance for each class measured over multiple periods against (i) a broad-based securities market index, and (ii) a peer group of mutual funds deemed appropriate by Fidelity and reviewed by the Board. The following charts considered by the Board show, over the one-, three-, and five-year periods ended December 31, 2011, as available, the cumulative total returns of Class K and the retail class of the fund, the cumulative total returns of a broad-based securities market index ("benchmark"), and a range of cumulative total returns of a peer group of mutual funds identified by Morningstar, Inc. as having an investment style similar to that of the fund based on underlying portfolio holdings. The box within each chart shows the 25th percentile return (top of box) and the 75th percentile return (bottom of box) of the peer group. Returns shown above the box are in the first quartile and returns shown below the box are in the fourth quartile. The percentage beaten numbers noted below each chart correspond to the percentile box and represent the percentage of funds in the peer group whose performance was equal to or lower than that of the class indicated.

Fidelity Mid-Cap Stock Fund

WSD180560

The Board reviewed the fund's relative investment performance against its peer group and noted that the performance of the retail class of the fund (the class with the longer performance record) was in the second quartile for the one- and five-year periods and the first quartile for the three-year period. The Board also noted that the investment performance of the fund was lower than its benchmark for the one- and five-year periods, although the three-year cumulative total return of the retail class compared favorably to its benchmark. The Board considered that the variations in performance between the fund's classes reflect the variations in class expenses, which result in lower performance for the higher expense class. The Board also reviewed the fund's performance since inception as well as performance in the current year.

The Board also considered that the fund's management fee is subject to upward or downward adjustment depending upon whether, and to what extent, the fund's investment performance for the performance period exceeds, or is exceeded by, the record (over the same period) of a Board-approved performance adjustment index. The Board noted that the performance adjustment provides FMR with a strong economic incentive to seek to achieve superior performance for the fund's shareholders and helps to more closely align the interests of FMR and the fund's shareholders.

Semiannual Report

Board Approval of Investment Advisory Contracts and
Management Fees - continued

Based on its review, the Board concluded that the nature, extent, and quality of services provided to the fund under the Advisory Contracts should benefit the fund's shareholders.

Competitiveness of Management Fee and Total Expense Ratio. The Board considered the fund's management fee and total expense ratio compared to "mapped groups" of competitive funds and classes. Fidelity creates "mapped groups" by combining similar Lipper investment objective categories that have comparable management fee characteristics. Combining Lipper investment objective categories aids the Board's management fee and total expense ratio comparisons by broadening the competitive group used for comparison and by reducing the number of universes to which various Fidelity funds are compared.

Management Fee . The Board considered two proprietary management fee comparisons for the 12-month periods shown in the chart below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group." The Total Mapped Group comparison focuses on a fund's standing relative to the total universe of comparable funds available to investors in terms of gross management fees before expense reimbursements or caps, and without giving effect to the fund's performance adjustment. "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than the fund's. For example, a TMG % of 10% means that 90% of the funds in the Total Mapped Group had higher management fees than the fund. The "Asset-Size Peer Group" (ASPG) comparison focuses on a fund's standing relative to non-Fidelity funds similar in size to the fund within the Total Mapped Group. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee characteristics, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which the fund's management fee ranked and the impact of the fund's performance adjustment, is also included in the chart and considered by the Board.

Semiannual Report

Fidelity Mid-Cap Stock Fund

WSD180562

The Board noted that the fund's management fee ranked below the median of its Total Mapped Group and below the median of its ASPG for 2011. The Board also noted the effect of the fund's negative performance adjustment on the fund's management fee ranking. The Board noted that the performance adjustment for each year represents calculations for performance periods that differ from the periods shown in the performance charts above.

Based on its review, the Board concluded that the fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered.

Total Expense Ratio . In its review of each class's total expense ratio, the Board considered the fund's management fee as well as other fund or class expenses, as applicable, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees. The Board also noted the effects of any waivers and reimbursements on fees and expenses, as well as the impact of the fund's performance adjustment. As part of its review, the Board also considered the current and historical total expense ratios of each class of the fund compared to competitive fund median expenses. Each class of the fund is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure.

The Board noted that the total expense ratio of each class ranked below its competitive median for 2011.

Fees Charged to Other Fidelity Clients . The Board also considered Fidelity fee structures and other information with respect to clients of FMR and its affiliates, such as other mutual funds advised or subadvised by FMR or its affiliates, pension plan clients, and other institutional clients. The Board noted the findings of the 2010 ad hoc joint committee (created with the board of other Fidelity funds), which reviewed and compared Fidelity's institutional investment advisory business with its business of providing services to the Fidelity funds, including the differences in services provided, fees charged, and costs incurred, as well as competition in their respective marketplaces.

Semiannual Report

Board Approval of Investment Advisory Contracts and
Management Fees - continued

Based on its review of total expense ratios and fees charged to other Fidelity clients, the Board concluded that the total expense ratio of each class of the fund was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability.  The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and its shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

On an annual basis, FMR presents to the Board Fidelity's profitability for the fund. Fidelity calculates the profitability for each fund, as well as aggregate profitability for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the books and records of Fidelity on which Fidelity's audited financial statements are based. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies.

PricewaterhouseCoopers LLP (PwC), independent registered public accounting firm and auditor to Fidelity and certain Fidelity funds, has been engaged annually by the Board as part of the Board's assessment of Fidelity's profitability analysis. PwC's engagement includes the review and assessment of Fidelity's methodologies used in determining the revenues and expenses attributable to Fidelity's mutual fund business, and completion of agreed-upon procedures surrounding the mathematical accuracy of fund profitability and its conformity to allocation methodologies. After considering PwC's reports issued under the engagement and information provided by Fidelity, the Board concluded that while other allocation methods may also be reasonable, Fidelity's profitability methodologies are reasonable in all material respects.

The Board also reviewed Fidelity's non-fund businesses and fall-out benefits related to the mutual fund business as well as cases where Fidelity's affiliates may benefit from or be related to the fund's business.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of the fund and was satisfied that the profitability was not excessive in the circumstances.

Semiannual Report

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale through increased services to the fund, through waivers or reimbursements, or through fee or expense reductions. The Board also noted that in 2009, it and the board of other Fidelity funds created an ad hoc committee (the Economies of Scale Committee) to analyze whether FMR attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board recognized that the fund's management contract incorporates a "group fee" structure, which provides for lower group fee rates as total fund assets under FMR's management increase, and for higher group fee rates as total fund assets under FMR's management decrease. FMR calculates the group fee rates based on a tiered asset "breakpoint" schedule that varies based on asset class. The Board considered that the group fee is designed to deliver the benefits of economies of scale to fund shareholders when total Fidelity fund assets increase, even if assets of any particular fund are unchanged or have declined, because some portion of Fidelity's costs are attributable to services provided to all Fidelity funds, and all funds benefit if those costs can be allocated among more assets. The Board concluded that, given the group fee structure, fund shareholders will benefit from lower management fees as assets under FMR's management increase at the fund complex level, regardless of whether Fidelity achieves any such economies of scale.

The Board concluded, taking into account the analysis of the Economies of Scale Committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.

Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Fidelity funds' Advisory Contracts, the Board requested and received additional information on certain topics, including (i) fund performance trends, actions to be taken by FMR to improve certain funds' overall performance, and Fidelity's long-term strategies for certain funds; (ii) the potential to further rationalize the Fidelity fund lineup with the possibility of achieving savings for the funds and Fidelity; (iii) Fidelity's compensation structure for portfolio managers and other key investment personnel; (iv) the amount of the investment that each portfolio manager has made in the Fidelity fund(s) that he or she manages; (v) the realization of fall-out benefits in certain Fidelity business units; (vi) Fidelity's group fee structures, the potential impact of regulatory changes on such structures, and the rationale for the individual fee rates of certain funds; (vii) fund profitability methodology, including Fidelity's cost allocation methodology, and the impact of certain factors on fund profitability results; (viii) trends regarding industry use of performance fee structures and the possibility of implementing performance fee structures for additional funds; and (ix) the impact of net redemptions from the Fidelity funds.

A fund files its complete schedule of portfolio holdings with the SEC for the first and third quarters of each fiscal year on Form N-Q. Forms N-Q are available on the SEC's web site at http://www.sec.gov . A fund's Forms N-Q may be reviewed and copied at the SEC's Public Reference Room in Washington, DC. Information regarding the operation of the SEC's Public Reference Room may be obtained by calling 1-800-SEC-0330. For a complete list of a fund's portfolio holdings, view the most recent holdings listing, semiannual report, or annual report on Fidelity's web site at http://www.fidelity.com, http://www.advisor.fidelity.com, or http://www.401k.com, as applicable.

Semiannual Report


Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (May 1, 2012 to October 31, 2012).

Actual Expenses

The first line of the accompanying table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Notes to Financial Statements

For the period ended October 31, 2012 (Unaudited)

1. Organization.

Fidelity® Small Cap Discovery Fund (the Fund) is a fund of Fidelity Commonwealth Trust (the Trust) and is authorized to issue an unlimited number of shares. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.

2. Investments in Fidelity Central Funds.

The Fund invests in Fidelity Central Funds, which are open-end investment companies available only to other investment companies and accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The Fund's Schedule of Investments lists each of the Fidelity Central Funds held as of period end, if any, as an investment of the Fund, but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of FMR.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) web site at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds are available on the SEC web site or upon request.

3. Significant Accounting Policies.

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. In accordance with valuation policies and procedures approved by the Board of Trustees (the Board), the Fund attempts to obtain prices from one or more third party pricing vendors or brokers to value its investments. When current market prices, quotations or rates are not readily available or reliable, securities will be fair valued in good faith by the FMR Fair Value Committee (the Committee), in

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

3. Significant Accounting Policies - continued

Security Valuation - continued

accordance with procedures adopted by the Fund's Board. Factors used in determining fair value vary by security type and may include market or security specific events. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees the Fund's valuation policies and procedures and is responsible for approving and reporting to the Board all fair value determinations.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows:

Equity securities, including restricted securities, for which market quotations are readily available, are valued at the last reported sale price or official closing price as reported by a third party pricing vendor on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. In the event there were no sales during the day or closing prices are not available, securities are valued at the last quoted bid price or may be valued using the last available price and are generally categorized as Level 2 in the hierarchy. For foreign equity securities, when significant market or security specific events arise, comparisons to the valuation of American Depositary Receipts (ADRs), futures contracts, Exchange-Traded Funds (ETFs) and certain indexes as well as quoted prices for similar securities are used and are categorized as Level 2 in the hierarchy. Utilizing these techniques may result in transfers between Level 1 and Level 2.

Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. Information on transfers between Levels 1 and 2, is included at the end of the Fund's Schedule of Investments.

Semiannual Report

3. Significant Accounting Policies - continued

Foreign Currency Translation. The Fund may use foreign currency contracts to facilitate transactions in foreign-denominated securities. Gains and losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts' terms.

Foreign-denominated assets, including investment securities, and liabilities are translated into U.S. dollars at the exchange rates at period end. Purchases and sales of investment securities, income and dividends received and expenses denominated in foreign currencies are translated into U.S. dollars at the exchange rate in effect on the transaction date.

The effects of exchange rate fluctuations on investments are included with the net realized and unrealized gain (loss) on investment securities. Other foreign currency transactions resulting in realized and unrealized gain (loss) are disclosed separately.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Fund is informed of the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The Fund estimates the components of distributions received that may be considered return of capital distributions or capital gain distributions. Interest income and distributions from the Fidelity Central Funds are accrued as earned. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for income taxes is required. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. A fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction. Foreign taxes are provided for based on the Fund's understanding of the tax rules and rates that exist in the foreign markets in which it invests.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Book-tax differences are primarily due to foreign currency transactions, net operating losses and losses deferred due to wash sales and excise tax regulations.

The federal tax cost of investment securities and unrealized appreciation (depreciation) as of period end were as follows:

Gross unrealized appreciation

$ 560,688,355

Gross unrealized depreciation

(135,142,353 )

Net unrealized appreciation (depreciation) on securities and other investments

$ 425,546,002

 

 

Tax cost

$ 2,938,560,694

Short-Term Trading (Redemption) Fees. Shares held by investors in the Fund less than 90 days are subject to a redemption fee equal to 1.50% of the net asset value of shares redeemed. All redemption fees, which reduce the proceeds of the shareholder redemption, are retained by the Fund and accounted for as an addition to paid in capital.

New Accounting Pronouncement. In December 2011, the Financial Accounting Standards Board issued Accounting Standard Update No. 2011-11, Disclosures about Offsetting Assets and Liabilities . The update creates new disclosure requirements requiring entities to disclose both gross and net information for derivatives and other financial instruments that are either offset in the Statement of Assets and Liabilities or

Semiannual Report

3. Significant Accounting Policies - continued

New Accounting Pronouncement - continued

subject to an enforceable master netting arrangement or similar agreement. The disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. Management is currently evaluating the impact of the update's adoption on the Fund's financial statement disclosures.

4. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $739,114,573 and $403,971,014, respectively.

5. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .45% of the Fund's average net assets and an annualized group fee rate that averaged .26% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. In addition, the management fee is subject to a performance adjustment (up to a maximum of ± .20% of the Fund's average net assets over a 36 month performance period). The upward or downward adjustment to the management fee is based on the Fund's relative investment performance as compared to an appropriate benchmark index. For the period, the total annualized management fee rate, including the performance adjustment, was .80% of the Fund's average net assets.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of FMR, is the Fund's transfer, dividend disbursing and shareholder servicing agent. FIIOC receives account fees and asset-based fees that vary according to account size and type of account. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period, the transfer agent fees were equivalent to an annualized rate of .23% of average net assets.

Accounting and Security Lending Fees. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, maintains the Fund's accounting records. The accounting fee is based on the level of average net assets for each month. Under a separate contract, FSC administers the security lending program. The security lending fee is based on the number and duration of lending transactions .

Notes to Financial Statements (Unaudited) - continued

5. Fees and Other Transactions with Affiliates - continued

Brokerage Commissions. The Fund placed a portion of its portfolio transactions with brokerage firms which are affiliates of the investment adviser. The commissions paid to these affiliated firms were $27,643 for the period.

Interfund Lending Program. Pursuant to an Exemptive Order issued by the SEC, the Fund, along with other registered investment companies having management contracts with FMR, may participate in an interfund lending program. This program provides an alternative credit facility allowing the funds to borrow from, or lend money to, other participating affiliated funds. At period end, there were no interfund loans outstanding. The Fund's activity in this program during the period for which loans were outstanding was as follows:

Borrower or Lender

Average Loan
Balance

Weighted Average Interest Rate

Interest
Expense

Borrower

$ 4,621,500

.45%

$ 346

6. Committed Line of Credit.

The Fund participates with other funds managed by FMR or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $3,503 and is reflected in Miscellaneous expenses on the Statement of Operations. During the period, there were no borrowings on this line of credit.

7. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. The value of loaned securities and

Semiannual Report

7. Security Lending - continued

cash collateral at period end are disclosed on the Fund's Statement of Assets and Liabilities. The value of securities loaned to FCM at period end was $7,792,083. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Total security lending income during the period amounted to $564,007, including $88,665 from securities loaned to FCM.

8. Expense Reductions.

Many of the brokers with whom FMR places trades on behalf of the Fund provided services to the Fund in addition to trade execution. These services included payments of certain expenses on behalf of the Fund totaling $64,371 for the period.

9. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Small Cap Discovery Fund

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract and sub-advisory agreements (together, the Advisory Contracts) for the fund. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.

The Board meets regularly and, at each of its meetings, considers factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board has established various standing committees, each composed of and chaired by Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of the fund's Advisory Contracts. The Board also meets as needed to consider matters specifically related to the Board's annual consideration of the renewal of Advisory Contracts. Members of the Board may also meet with trustees of other Fidelity funds through ad hoc joint committees to discuss certain matters relevant to the Fidelity funds.

At its July 2012 meeting, the Board of Trustees, including the Independent Trustees, unanimously determined to renew the fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services to be provided to the fund and its shareholders (including the investment performance of the fund); (ii) the competitiveness of the fund's management fee and total expense ratio relative to peer funds; (iii) the total costs of the services to be provided by and the profits to be realized by Fidelity from its relationship with the fund; (iv) the extent to which economies of scale exist and would be realized as the fund grows; and (v) whether fee levels reflect these economies of scale, if any, for the benefit of fund shareholders.

In considering whether to renew the Advisory Contracts for the fund, the Board reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts is in the best interests of the fund and its shareholders and that the compensation payable under the Advisory Contracts is fair and reasonable. The Board's decision to renew the Advisory Contracts was not based on any single factor, but rather was based on a comprehensive consideration of all the information provided to the Board at its meetings throughout the year. The Board, in reaching its determination to renew the Advisory Contracts, is aware that shareholders in the fund have a broad range of investment choices available to them, including a wide choice among mutual funds offered by Fidelity's competitors, and that the fund's shareholders, who have the opportunity to review and weigh the disclosure provided by the fund in its prospectus and other public disclosures, have chosen to invest in this fund, managed by Fidelity.

Nature, Extent, and Quality of Services Provided. The Board considered the staffing within the investment adviser, FMR, and the sub-advisers (together, the Investment Advisers), including the backgrounds of the fund's investment personnel, and also considered the fund's investment objective, strategies, and related investment philosophy. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the portfolio manager compensation program and whether this structure provides appropriate incentives to act in the best interests of the fund.

Resources Dedicated to Investment Management and Support Services . The Board and the Fund Oversight and Research Committees reviewed the general qualifications and capabilities of the Investment Advisers' investment staff, including its size, education, experience, and resources, as well as the Investment Advisers' approach to recruiting, training, managing, and compensating investment personnel. The Board also noted that FMR has continued to increase the resources devoted to non-U.S. offices, including expansion of Fidelity's global investment organization. The Board noted that Fidelity's analysts have extensive resources, tools and capabilities that allow them to conduct sophisticated quantitative and fundamental analysis, as well as credit analysis of issuers, counterparties and guarantors. The Board also believes that Fidelity's investment professionals have sufficient access to global information and data so as to provide competitive investment results over time, and that those professionals also have access to sophisticated tools that permit them to assess portfolio construction and risk and performance attribution characteristics continuously, as well as to transmit new information and research conclusions rapidly around the world. Additionally, in its deliberations, the Board considered the Investment Advisers' trading and risk management capabilities and resources, which are an integral part of the investment management process.

Shareholder and Administrative Services . The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for the fund; (ii) the nature and extent of the supervision of third party service providers, principally custodians and subcustodians; and (iii) the resources devoted to, and the record of compliance with, the fund's compliance policies and procedures. The Board also reviewed the allocation of fund brokerage, including allocations to brokers affiliated with the Investment Advisers, the use of brokerage commissions to pay fund expenses, and the use of "soft" commission dollars to pay for research services.

Semiannual Report

The Board noted that the growth of fund assets over time across the complex allows Fidelity to reinvest in the development of services designed to enhance the value or convenience of the Fidelity funds as investment vehicles. These services include 24-hour access to account information and market information through telephone representatives and over the Internet, investor education materials and asset allocation tools, and the expanded availability of Fidelity Investor Centers.

Investment in a Large Fund Family . The Board considered the benefits to shareholders of investing in a Fidelity fund, including the benefits of investing in a fund that is part of a large family of funds offering a variety of investment disciplines and providing a large variety of mutual fund investor services. The Board noted that Fidelity had taken, or had made recommendations that resulted in the Fidelity funds taking, a number of actions over the previous year that benefited particular funds, including (i) continuing to dedicate additional resources to investment research and support of the senior management team that oversees asset management; (ii) persisting in efforts to enhance Fidelity's research capabilities, in particular, international research; (iii) launching new funds and making other enhancements to meet client needs for global and income-oriented solutions; (iv) continuing to launch dedicated lower cost underlying funds to meet investment management's portfolio construction needs related to expanding underlying fund options, specifically for the Freedom Fund product lines; (v) adopting a "Stock Selector" sector neutral investment approach and employing a team of portfolio managers who are sector specialists to manage certain funds; (vi) rationalizing product lines and gaining increased efficiencies through the mergers of several funds into other funds; (vii) strengthening the Spartan Index Fund product line by adding new funds and/or new low-cost institutional share classes, restructuring fund expenses to accommodate new classes, and reducing investment minimums for certain classes of shares; (viii) modifying the eligibility criteria for Institutional Class shares to increase their appeal to government entities and charitable investors; and (ix) reducing certain transfer agent fee rates.

Investment Performance . The Board considered whether the fund has operated in accordance with its investment objective, as well as its record of compliance with its investment restrictions. It also reviewed the fund's absolute investment performance, as well as the fund's relative investment performance measured over multiple periods against (i) a broad-based securities market index, and (ii) a peer group of mutual funds deemed appropriate by Fidelity and reviewed by the Board. The following charts considered by the Board show, over the one-, three-, and five-year periods ended December 31, 2011, the fund's cumulative total returns, the cumulative total returns of a broad-based securities market index ("benchmark"), and a range of cumulative total returns of a peer group of mutual funds identified by Morningstar, Inc. as having an investment style similar to that of the fund based on underlying portfolio holdings. The box within each chart shows the 25th percentile return (top of box) and the 75th percentile return (bottom of box) of the peer group. Returns shown above the box are in the first quartile and returns shown below the box are in the fourth quartile. The percentage beaten number noted below each chart corresponds to the percentile box and represents the percentage of funds in the peer group whose performance was equal to or lower than that of the fund.

Fidelity Small Cap Discovery Fund

The Board reviewed the fund's relative investment performance against its peer group and noted that the performance of the fund was in the first quartile for all the periods shown. The Board also noted that the investment performance of the fund compared favorably to its benchmark for all the periods shown. The Board also reviewed the fund's performance since inception as well as performance in the current year.

The Board also considered that the fund's management fee is subject to upward or downward adjustment depending upon whether, and to what extent, the fund's investment performance for the performance period exceeds, or is exceeded by, the record (over the same period) of a Board-approved performance adjustment index. The Board noted that the performance adjustment provides FMR with a strong economic incentive to seek to achieve superior performance for the fund's shareholders and helps to more closely align the interests of FMR and the fund's shareholders.

Based on its review, the Board concluded that the nature, extent, and quality of services provided to the fund under the Advisory Contracts should benefit the fund's shareholders.

Competitiveness of Management Fee and Total Expense Ratio. The Board considered the fund's management fee and total expense ratio compared to "mapped groups" of competitive funds and classes. Fidelity creates "mapped groups" by combining similar Lipper investment objective categories that have comparable management fee characteristics. Combining Lipper investment objective categories aids the Board's management fee and total expense ratio comparisons by broadening the competitive group used for comparison and by reducing the number of universes to which various Fidelity funds are compared.

Semiannual Report

Management Fee . The Board considered two proprietary management fee comparisons for the 12-month periods shown in the chart below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group." The Total Mapped Group comparison focuses on a fund's standing relative to the total universe of comparable funds available to investors in terms of gross management fees before expense reimbursements or caps, and without giving effect to the fund's performance adjustment. "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than the fund's. For example, a TMG % of 13% means that 87% of the funds in the Total Mapped Group had higher management fees than the fund. The "Asset-Size Peer Group" (ASPG) comparison focuses on a fund's standing relative to non-Fidelity funds similar in size to the fund within the Total Mapped Group. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee characteristics, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which the fund's management fee ranked and the impact of the fund's performance adjustment, is also included in the chart and considered by the Board.

Management Fees - continued

The Board noted that the fund's management fee ranked below the median of its Total Mapped Group and below the median of its ASPG for 2011. The Board also noted the effect of the fund's positive performance adjustment on the fund's management fee ranking. The Board noted that the performance adjustment for each year represents calculations for performance periods that differ from the periods shown in the performance charts above.

Based on its review, the Board concluded that the fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered.

Total Expense Ratio . In its review of the fund's total expense ratio, the Board considered the fund's management fee as well as other fund expenses, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees. The Board also noted the effects of any waivers and reimbursements on fees and expenses, as well as the impact of the fund's performance adjustment. As part of its review, the Board also considered the current and historical total expense ratios of the fund compared to competitive fund median expenses. The fund is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure.

The Board noted that the fund's total expense ratio ranked below its competitive median for 2011.

Fees Charged to Other Fidelity Clients . The Board also considered Fidelity fee structures and other information with respect to clients of FMR and its affiliates, such as other mutual funds advised or subadvised by FMR or its affiliates, pension plan clients, and other institutional clients. The Board noted the findings of the 2010 ad hoc joint committee (created with the board of other Fidelity funds), which reviewed and compared Fidelity's institutional investment advisory business with its business of providing services to the Fidelity funds, including the differences in services provided, fees charged, and costs incurred, as well as competition in their respective marketplaces.

Based on its review of total expense ratios and fees charged to other Fidelity clients, the Board concluded that the fund's total expense ratio was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability.  The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and its shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

On an annual basis, FMR presents to the Board Fidelity's profitability for the fund. Fidelity calculates the profitability for each fund, as well as aggregate profitability for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the books and records of Fidelity on which Fidelity's audited financial statements are based. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies.

Semiannual Report

PricewaterhouseCoopers LLP (PwC), independent registered public accounting firm and auditor to Fidelity and certain Fidelity funds, has been engaged annually by the Board as part of the Board's assessment of Fidelity's profitability analysis. PwC's engagement includes the review and assessment of Fidelity's methodologies used in determining the revenues and expenses attributable to Fidelity's mutual fund business, and completion of agreed-upon procedures surrounding the mathematical accuracy of fund profitability and its conformity to allocation methodologies. After considering PwC's reports issued under the engagement and information provided by Fidelity, the Board concluded that while other allocation methods may also be reasonable, Fidelity's profitability methodologies are reasonable in all material respects.

The Board also reviewed Fidelity's non-fund businesses and fall-out benefits related to the mutual fund business as well as cases where Fidelity's affiliates may benefit from or be related to the fund's business.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of the fund and was satisfied that the profitability was not excessive in the circumstances.

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale through increased services to the fund, through waivers or reimbursements, or through fee or expense reductions. The Board also noted that in 2009, it and the board of other Fidelity funds created an ad hoc committee (the Economies of Scale Committee) to analyze whether FMR attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board recognized that the fund's management contract incorporates a "group fee" structure, which provides for lower group fee rates as total fund assets under FMR's management increase, and for higher group fee rates as total fund assets under FMR's management decrease. FMR calculates the group fee rates based on a tiered asset "breakpoint" schedule that varies based on asset class. The Board considered that the group fee is designed to deliver the benefits of economies of scale to fund shareholders when total Fidelity fund assets increase, even if assets of any particular fund are unchanged or have declined, because some portion of Fidelity's costs are attributable to services provided to all Fidelity funds, and all funds benefit if those costs can be allocated among more assets. The Board concluded that, given the group fee structure, fund shareholders will benefit from lower management fees as assets under FMR's management increase at the fund complex level, regardless of whether Fidelity achieves any such economies of scale.

Management Fees - continued

The Board concluded, taking into account the analysis of the Economies of Scale Committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.

Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Fidelity funds' Advisory Contracts, the Board requested and received additional information on certain topics, including (i) fund performance trends, actions to be taken by FMR to improve certain funds' overall performance, and Fidelity's long-term strategies for certain funds; (ii) the potential to further rationalize the Fidelity fund lineup with the possibility of achieving savings for the funds and Fidelity; (iii) Fidelity's compensation structure for portfolio managers and other key investment personnel; (iv) the amount of the investment that each portfolio manager has made in the Fidelity fund(s) that he or she manages; (v) the realization of fall-out benefits in certain Fidelity business units; (vi) Fidelity's group fee structures, the potential impact of regulatory changes on such structures, and the rationale for the individual fee rates of certain funds; (vii) fund profitability methodology, including Fidelity's cost allocation methodology, and the impact of certain factors on fund profitability results; (viii) trends regarding industry use of performance fee structures and the possibility of implementing performance fee structures for additional funds; and (ix) the impact of net redemptions from the Fidelity funds.

Based on its evaluation of all of the conclusions noted above, and after considering all factors it believed relevant, the Board ultimately concluded that the advisory fee structures are fair and reasonable, and that the fund's Advisory Contracts should be renewed.

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (May 1, 2012 to October 31, 2012).

Actual Expenses

The first line of the accompanying table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of FMR.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) web site at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds are available on the SEC web site or upon request.

3. Significant Accounting Policies.

The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the financial statements were issued have been evaluated in the preparation of the financial statements. The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. In accordance with valuation policies and procedures approved by the Board of Trustees (the Board), the Fund attempts to obtain prices from one or more third party pricing vendors or brokers to value its investments. When current market prices, quotations or rates are not readily available or reliable, securities will be fair valued in good faith by the FMR Fair Value Committee (the Committee), in accordance with procedures adopted by the Fund's Board. Factors used in determining

Security Valuation - continued

fair value vary by security type and may include market or security specific events, changes in interest rates and credit quality. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees the Fund's valuation policies and procedures and is responsible for approving and reporting to the Board all fair value determinations.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

Level 1 - quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows:

Equity securities, including restricted securities, for which market quotations are readily available, are valued at the last reported sale price or official closing price as reported by a third party pricing vendor on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. In the event there were no sales during the day or closing prices are not available, securities are valued at the last quoted bid price or may be valued using the last available price and are generally categorized as Level 2 in the hierarchy. For foreign equity securities, when significant market or security specific events arise, comparisons to the valuation of American Depositary Receipts (ADRs), futures contracts, Exchange-Traded Funds (ETFs) and certain indexes as well as quoted prices for similar securities are used and are categorized as Level 2 in the hierarchy. Utilizing these techniques may result in transfers between Level 1 and Level 2.

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing vendors or from brokers who make markets in such securities. For U.S. government and government agency obligations, pricing vendors utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type as well as broker-supplied prices and are generally categorized as Level 2 in the hierarchy. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing vendors. These are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Foreign Currency Translation. The Fund may use foreign currency contracts to facilitate transactions in foreign-denominated securities. Gains and losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts' terms.

Foreign-denominated assets, including investment securities, and liabilities are translated into U.S. dollars at the exchange rates at period end. Purchases and sales of investment securities, income and dividends received and expenses denominated in foreign currencies are translated into U.S. dollars at the exchange rate in effect on the transaction date.

The effects of exchange rate fluctuations on investments are included with the net realized and unrealized gain (loss) on investment securities. Other foreign currency transactions resulting in realized and unrealized gain (loss) are disclosed separately.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the Fund is informed of the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The Fund estimates the components of distributions received that may be considered return of capital distributions or capital gain distributions. Interest income and distributions from the Fidelity Central Funds are accrued as earned. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for income taxes is required. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. A fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction. Foreign taxes are provided for based on the Fund's understanding of the tax rules and rates that exist in the foreign markets in which it invests.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Book-tax differences are primarily due to futures transactions, foreign currency transactions, passive foreign investment companies (PFIC), partnerships, net operating losses, capital loss carryforwards and losses deferred due to wash sales.

The federal tax cost of investment securities and unrealized appreciation (depreciation) as of period end were as follows:

Gross unrealized appreciation

$ 336,540

Gross unrealized depreciation

(147,494 )

Net unrealized appreciation (depreciation) on securities and other investments

$ 189,046

 

 

Tax cost

$ 2,707,257

Short-Term Trading (Redemption) Fees. Shares held by investors in the Fund less than 90 days are subject to a redemption fee equal to 2.00% of the net asset value of shares redeemed. All redemption fees, which reduce the proceeds of the shareholder redemption, are retained by the Fund and accounted for as an addition to paid in capital.

Restricted Securities. The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of the Fund's Schedule of Investments.

New Accounting Pronouncement. In December 2011, the Financial Accounting Standards Board issued Accounting Standard Update No. 2011-11, Disclosures about Offsetting Assets and Liabilities . The update creates new disclosure requirements requiring entities to disclose both gross and net information for derivatives and other financial instruments that are either offset in the Statement of Assets and Liabilities or subject to an enforceable master netting arrangement or similar agreement. The disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. Management is currently evaluating the impact of the update's adoption on the Fund's financial statement disclosures.

4. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. The Fund's investment objective allows the Fund to enter into various types of derivative contracts, including futures contracts. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified instrument based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party.

The Fund used derivatives to increase returns and to manage exposure to certain risks as defined below. The success of any strategy involving derivatives depends on analysis of numerous economic factors, and if the strategies for investment do not work as intended, the Fund may not achieve its objectives.

The Fund's use of derivatives increased or decreased its exposure to the following risk:

Equity Risk

Equity risk relates to the fluctuations in the value of financial instruments as a result of changes in market prices (other than those arising from interest rate risk or foreign exchange risk), whether caused by factors specific to an individual investment, its issuer, or all factors affecting all instruments traded in a market or market segment.

Semiannual Report

4. Derivative Instruments - continued

Risk Exposures and the Use of Derivative Instruments - continued

The Fund is also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that the Fund will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to the Fund. Counterparty credit risk related to exchange-traded futures contracts is minimal because of the protection provided by the exchange on which they trade.

Investing in derivatives may involve greater risks than investing in the underlying assets directly and, to varying degrees, may involve risk of loss in excess of any initial investment and collateral received and amounts recognized in the Statement of Assets and Liabilities. In addition, there may be the risk that the change in value of the derivative contract does not correspond to the change in value of the underlying instrument.

Futures Contracts. A futures contract is an agreement between two parties to buy or sell a specified underlying instrument for a fixed price at a specified future date. The Fund used futures contracts to manage its exposure to the stock market.

Upon entering into a futures contract, a fund is required to deposit either cash or securities (initial margin) with a clearing broker in an amount equal to a certain percentage of the face value of the contract. Futures contracts are marked-to-market daily and subsequent payments (variation margin) are made or received by a fund depending on the daily fluctuations in the value of the futures contracts and are recorded as unrealized appreciation or (depreciation). This receivable and/or payable is included in daily variation margin on futures contracts in the Statement of Assets and Liabilities. Realized gain or (loss) is recorded upon the expiration or closing of a futures contract.

Any open futures contracts at period end are shown in the Schedule of Investments under the caption "Futures Contracts." The underlying face amount at value reflects each contract's exposure to the underlying instrument at period end and is representative of activity for the period. Securities deposited to meet initial margin requirements are identified in the Schedule of Investments.

During the period, the Fund recognized net realized gain (loss) of $3,316 and a change in net unrealized appreciation (depreciation) of $(1,965) related to its investment in futures contracts. These amounts are included in the Statement of Operations.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $1,000,610 and $1,282,995, respectively.

6. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .45% of the Fund's average net assets and an annualized group fee rate that averaged .26% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. In addition, the management fee is subject to a performance adjustment (up to a maximum of ±.20% of the Fund's average net assets over a 36 month performance period). The upward or downward adjustment to the management fee is based on the Fund's relative investment performance as compared to an appropriate benchmark index. For the period, the total annualized management fee rate, including the performance adjustment, was .46% of the Fund's average net assets.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of FMR, is the Fund's transfer, dividend disbursing and shareholder servicing agent. FIIOC receives account fees and asset-based fees that vary according to account size and type of account. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period, the transfer agent fees were equivalent to an annualized rate of .24% of average net assets.

Accounting and Security Lending Fees. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, maintains the Fund's accounting records. The accounting fee is based on the level of average net assets for each month. Under a separate contract, FSC administers the security lending program. The security lending fee is based on the number and duration of lending transactions.

Brokerage Commissions. The Fund placed a portion of its portfolio transactions with brokerage firms which are affiliates of the investment adviser. The commissions paid to these affiliated firms were $57 for the period.

7. Committed Line of Credit.

The Fund participates with other funds managed by FMR or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $4 and is reflected in Miscellaneous expenses on the Statement of Operations. During the period, there were no borrowings on this line of credit.

Semiannual Report

8. Security Lending.

The Fund lends portfolio securities through a lending agent from time to time in order to earn additional income. For equity securities, a lending agent is used and may loan securities to certain qualified borrowers, including Fidelity Capital Markets (FCM), a broker-dealer affiliated with the Fund. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. Any cash collateral received is invested in the Fidelity Securities Lending Cash Central Fund. The value of loaned securities and cash collateral at period end are disclosed on the Fund's Statement of Assets and Liabilities. The value of securities loaned to FCM at period end was $6,549. Security lending income represents the income earned on investing cash collateral, less rebates paid to borrowers and any lending agent fees associated with the loan, plus any premium payments received for lending certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from Fidelity Central Funds. Total security lending income during the period amounted to $246, including $20 from securities loaned to FCM.

9. Expense Reductions.

Many of the brokers with whom FMR places trades on behalf of the Fund provided services to the Fund in addition to trade execution. These services included payments of certain expenses on behalf of the Fund totaling $100 for the period.

10. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Small Cap Stock Fund

Each year, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract and sub-advisory agreements (together, the Advisory Contracts) for the fund. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information relevant to the renewal of the Advisory Contracts throughout the year.

The Board meets regularly and, at each of its meetings, considers factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board has established various standing committees, each composed of and chaired by Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of the fund's Advisory Contracts. The Board also meets as needed to consider matters specifically related to the Board's annual consideration of the renewal of Advisory Contracts. Members of the Board may also meet with trustees of other Fidelity funds through ad hoc joint committees to discuss certain matters relevant to the Fidelity funds.

At its July 2012 meeting, the Board of Trustees, including the Independent Trustees, unanimously determined to renew the fund's Advisory Contracts. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services to be provided to the fund and its shareholders (including the investment performance of the fund); (ii) the competitiveness of the fund's management fee and total expense ratio relative to peer funds; (iii) the total costs of the services to be provided by and the profits to be realized by Fidelity from its relationship with the fund; (iv) the extent to which economies of scale exist and would be realized as the fund grows; and (v) whether fee levels reflect these economies of scale, if any, for the benefit of fund shareholders.

In considering whether to renew the Advisory Contracts for the fund, the Board reached a determination, with the assistance of fund counsel and Independent Trustees' counsel and through the exercise of its business judgment, that the renewal of the Advisory Contracts is in the best interests of the fund and its shareholders and that the compensation payable under the Advisory Contracts is fair and reasonable. The Board's decision to renew the Advisory Contracts was not based on any single factor, but rather was based on a comprehensive consideration of all the information provided to the Board at its meetings throughout the year. The Board, in reaching its determination to renew the Advisory Contracts, is aware that shareholders in the fund have a broad range of investment choices available to them, including a wide choice among mutual funds offered by Fidelity's competitors, and that the fund's shareholders, who have the opportunity to review and weigh the disclosure provided by the fund in its prospectus and other public disclosures, have chosen to invest in this fund, managed by Fidelity.

Nature, Extent, and Quality of Services Provided. The Board considered the staffing within the investment adviser, FMR, and the sub-advisers (together, the Investment Advisers), including the backgrounds of the fund's investment personnel, and also considered the fund's investment objective, strategies, and related investment philosophy. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the portfolio manager compensation program and whether this structure provides appropriate incentives to act in the best interests of the fund.

Resources Dedicated to Investment Management and Support Services . The Board and the Fund Oversight and Research Committees reviewed the general qualifications and capabilities of the Investment Advisers' investment staff, including its size, education, experience, and resources, as well as the Investment Advisers' approach to recruiting, training, managing, and compensating investment personnel. The Board also noted that FMR has continued to increase the resources devoted to non-U.S. offices, including expansion of Fidelity's global investment organization. The Board noted that Fidelity's analysts have extensive resources, tools and capabilities that allow them to conduct sophisticated quantitative and fundamental analysis, as well as credit analysis of issuers, counterparties and guarantors. The Board also believes that Fidelity's investment professionals have sufficient access to global information and data so as to provide competitive investment results over time, and that those professionals also have access to sophisticated tools that permit them to assess portfolio construction and risk and performance attribution characteristics continuously, as well as to transmit new information and research conclusions rapidly around the world. Additionally, in its deliberations, the Board considered the Investment Advisers' trading and risk management capabilities and resources, which are an integral part of the investment management process.

Shareholder and Administrative Services . The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, and shareholder services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for the fund; (ii) the nature and extent of the supervision of third party service providers, principally custodians and subcustodians; and (iii) the resources devoted to, and the record of compliance with, the fund's compliance policies and procedures. The Board also reviewed the allocation of fund brokerage, including allocations to brokers affiliated with the Investment Advisers, the use of brokerage commissions to pay fund expenses, and the use of "soft" commission dollars to pay for research services.

Semiannual Report

The Board noted that the growth of fund assets over time across the complex allows Fidelity to reinvest in the development of services designed to enhance the value or convenience of the Fidelity funds as investment vehicles. These services include 24-hour access to account information and market information through telephone representatives and over the Internet, investor education materials and asset allocation tools, and the expanded availability of Fidelity Investor Centers.

Investment in a Large Fund Family . The Board considered the benefits to shareholders of investing in a Fidelity fund, including the benefits of investing in a fund that is part of a large family of funds offering a variety of investment disciplines and providing a large variety of mutual fund investor services. The Board noted that Fidelity had taken, or had made recommendations that resulted in the Fidelity funds taking, a number of actions over the previous year that benefited particular funds, including (i) continuing to dedicate additional resources to investment research and support of the senior management team that oversees asset management; (ii) persisting in efforts to enhance Fidelity's research capabilities, in particular, international research; (iii) launching new funds and making other enhancements to meet client needs for global and income-oriented solutions; (iv) continuing to launch dedicated lower cost underlying funds to meet investment management's portfolio construction needs related to expanding underlying fund options, specifically for the Freedom Fund product lines; (v) adopting a "Stock Selector" sector neutral investment approach and employing a team of portfolio managers who are sector specialists to manage certain funds; (vi) rationalizing product lines and gaining increased efficiencies through the mergers of several funds into other funds; (vii) strengthening the Spartan Index Fund product line by adding new funds and/or new low-cost institutional share classes, restructuring fund expenses to accommodate new classes, and reducing investment minimums for certain classes of shares; (viii) modifying the eligibility criteria for Institutional Class shares to increase their appeal to government entities and charitable investors; and (ix) reducing certain transfer agent fee rates.

Investment Performance . The Board considered whether the fund has operated in accordance with its investment objective, as well as its record of compliance with its investment restrictions. It also reviewed the fund's absolute investment performance, as well as the fund's relative investment performance measured over multiple periods against (i) a broad-based securities market index, and (ii) a peer group of mutual funds deemed appropriate by Fidelity and reviewed by the Board. The following charts considered by the Board show, over the one-, three-, and five-year periods ended December 31, 2011, the fund's cumulative total returns, the cumulative total returns of a broad-based securities market index ("benchmark"), and a range of cumulative total returns of a peer group of mutual funds identified by Morningstar, Inc. as having an investment style similar to that of the fund based on underlying portfolio holdings. The box within each chart shows the 25th percentile return (top of box) and the 75th percentile return (bottom of box) of the peer group. Returns shown above the box are in the first quartile and returns shown below the box are in the fourth quartile. The percentage beaten number noted below each chart corresponds to the percentile box and represents the percentage of funds in the peer group whose performance was equal to or lower than that of the fund.

The Board reviewed the fund's relative investment performance against its peer group and noted that the performance of the fund was in the fourth quartile for the one-year period, the first quartile for the three-year period, and the second quartile for the five-year period. The Board also noted that the investment performance of the fund compared favorably to its benchmark for the three- and five-year periods, although the fund's one-year total return was lower than its benchmark. The Board noted that there was a portfolio management change for the fund in November 2011. The Board also reviewed the fund's performance since inception as well as performance in the current year.

The Board also considered that the fund's management fee is subject to upward or downward adjustment depending upon whether, and to what extent, the fund's investment performance for the performance period exceeds, or is exceeded by, the record (over the same period) of a Board-approved performance adjustment index. The Board noted that the performance adjustment provides FMR with a strong economic incentive to seek to achieve superior performance for the fund's shareholders and helps to more closely align the interests of FMR and the fund's shareholders.

Semiannual Report

Based on its review, the Board concluded that the nature, extent, and quality of services provided to the fund under the Advisory Contracts should benefit the fund's shareholders.

Competitiveness of Management Fee and Total Expense Ratio. The Board considered the fund's management fee and total expense ratio compared to "mapped groups" of competitive funds and classes. Fidelity creates "mapped groups" by combining similar Lipper investment objective categories that have comparable management fee characteristics. Combining Lipper investment objective categories aids the Board's management fee and total expense ratio comparisons by broadening the competitive group used for comparison and by reducing the number of universes to which various Fidelity funds are compared.

Management Fee . The Board considered two proprietary management fee comparisons for the 12-month periods shown in the chart below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group." The Total Mapped Group comparison focuses on a fund's standing relative to the total universe of comparable funds available to investors in terms of gross management fees before expense reimbursements or caps, and without giving effect to the fund's performance adjustment. "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than the fund's. For example, a TMG % of 13% means that 87% of the funds in the Total Mapped Group had higher management fees than the fund. The "Asset-Size Peer Group" (ASPG) comparison focuses on a fund's standing relative to non-Fidelity funds similar in size to the fund within the Total Mapped Group. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee characteristics, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which the fund's management fee ranked and the impact of the fund's performance adjustment, is also included in the chart and considered by the Board.

The Board noted that the fund's management fee ranked below the median of its Total Mapped Group and below the median of its ASPG for 2011. The Board also noted the effect of the fund's positive performance adjustment on the fund's management fee ranking. The Board noted that the performance adjustment for each year represents calculations for performance periods that differ from the periods shown in the performance charts above.

Based on its review, the Board concluded that the fund's management fee is fair and reasonable in light of the services that the fund receives and the other factors considered.

Total Expense Ratio . In its review of the fund's total expense ratio, the Board considered the fund's management fee as well as other fund expenses, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees. The Board also noted the effects of any waivers and reimbursements on fees and expenses, as well as the impact of the fund's performance adjustment. As part of its review, the Board also considered the current and historical total expense ratios of the fund compared to competitive fund median expenses. The fund is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure.

The Board noted that the fund's total expense ratio ranked below its competitive median for 2011.

Semiannual Report

Fees Charged to Other Fidelity Clients . The Board also considered Fidelity fee structures and other information with respect to clients of FMR and its affiliates, such as other mutual funds advised or subadvised by FMR or its affiliates, pension plan clients, and other institutional clients. The Board noted the findings of the 2010 ad hoc joint committee (created with the board of other Fidelity funds), which reviewed and compared Fidelity's institutional investment advisory business with its business of providing services to the Fidelity funds, including the differences in services provided, fees charged, and costs incurred, as well as competition in their respective marketplaces.

Based on its review of total expense ratios and fees charged to other Fidelity clients, the Board concluded that the fund's total expense ratio was reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability.  The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and its shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

On an annual basis, FMR presents to the Board Fidelity's profitability for the fund. Fidelity calculates the profitability for each fund, as well as aggregate profitability for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the books and records of Fidelity on which Fidelity's audited financial statements are based. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies.

PricewaterhouseCoopers LLP (PwC), independent registered public accounting firm and auditor to Fidelity and certain Fidelity funds, has been engaged annually by the Board as part of the Board's assessment of Fidelity's profitability analysis. PwC's engagement includes the review and assessment of Fidelity's methodologies used in determining the revenues and expenses attributable to Fidelity's mutual fund business, and completion of agreed-upon procedures surrounding the mathematical accuracy of fund profitability and its conformity to allocation methodologies. After considering PwC's reports issued under the engagement and information provided by Fidelity, the Board concluded that while other allocation methods may also be reasonable, Fidelity's profitability methodologies are reasonable in all material respects.

The Board also reviewed Fidelity's non-fund businesses and fall-out benefits related to the mutual fund business as well as cases where Fidelity's affiliates may benefit from or be related to the fund's business.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of the fund and was satisfied that the profitability was not excessive in the circumstances.

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale through increased services to the fund, through waivers or reimbursements, or through fee or expense reductions. The Board also noted that in 2009, it and the board of other Fidelity funds created an ad hoc committee (the Economies of Scale Committee) to analyze whether FMR attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board recognized that the fund's management contract incorporates a "group fee" structure, which provides for lower group fee rates as total fund assets under FMR's management increase, and for higher group fee rates as total fund assets under FMR's management decrease. FMR calculates the group fee rates based on a tiered asset "breakpoint" schedule that varies based on asset class. The Board considered that the group fee is designed to deliver the benefits of economies of scale to fund shareholders when total Fidelity fund assets increase, even if assets of any particular fund are unchanged or have declined, because some portion of Fidelity's costs are attributable to services provided to all Fidelity funds, and all funds benefit if those costs can be allocated among more assets. The Board concluded that, given the group fee structure, fund shareholders will benefit from lower management fees as assets under FMR's management increase at the fund complex level, regardless of whether Fidelity achieves any such economies of scale.

The Board concluded, taking into account the analysis of the Economies of Scale Committee, that economies of scale, if any, are being appropriately shared between fund shareholders and Fidelity.

Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Fidelity funds' Advisory Contracts, the Board requested and received additional information on certain topics, including (i) fund performance trends, actions to be taken by FMR to improve certain funds' overall performance, and Fidelity's long-term strategies for certain funds; (ii) the potential to further rationalize the Fidelity fund lineup with the possibility of achieving savings for the funds and Fidelity; (iii) Fidelity's compensation structure for portfolio managers and other key investment personnel; (iv) the amount of the investment that each portfolio manager has made in the Fidelity fund(s) that he or she manages; (v) the realization of fall-out benefits in certain Fidelity business units; (vi) Fidelity's group fee structures, the potential impact of regulatory changes on such structures, and the rationale for the individual fee rates of certain funds; (vii) fund profitability methodology, including Fidelity's cost allocation methodology, and the impact of certain factors on fund profitability results; (viii) trends regarding industry use of performance fee structures and the possibility of implementing performance fee structures for additional funds; and (ix) the impact of net redemptions from the Fidelity funds.

Semiannual Report

Based on its evaluation of all of the conclusions noted above, and after considering all factors it believed relevant, the Board ultimately concluded that the advisory fee structures are fair and reasonable, and that the fund's Advisory Contracts should be renewed.
