Chairman’s Message

(photograph of Edward C. Johnson 3d)

Dear Shareholder:

During the past year or so, much has been reported about the mutual fund industry, and much of it has been more critical than I believe is warranted. Allegations that some companies have been less than forthright with their shareholders have cast a shadow on the entire industry. I continue to find these reports disturbing, and assert that they do not create an accurate picture of the industry overall. Therefore, I would like to remind every one where Fidelity stands on these issues. I will say two things specifically regarding allegations that some mutual fund companies were in violation of the Securities and Exchange Commission’s forward pricing rules or were involved in so called “market timing” activities.

First, Fidelity has no agreements that permit customers who buy fund shares after 4 p.m. to obtain the 4 p.m. price. This is not a new policy. This is not to say that some one could not deceive the company through fraudulent acts. However, we are extremely diligent in preventing fraud from occurring in this manner and in every other. But I underscore again that Fidelity has no so called “agreements” that sanction illegal practices.

Second, Fidelity continues to stand on record, as we have for years, in opposition to predatory short term trading that adversely affects shareholders in a mutual fund. Back in the 1980s, we initiated a fee which is returned to the fund and, therefore, to investors to discourage this activity. Further, we took the lead several years ago in developing a Fair Value Pricing Policy to prevent market timing on foreign securities in our funds. I am confident we will find other ways to make it more difficult for predatory traders to operate. However, this will only be achieved through close cooperation among regulators, legislators and the industry.

Yes, there have been unfortunate instances of unethical and illegal activity within the mutual fund industry from time to time. That is true of any industry. When this occurs, confessed or convicted offenders should be dealt with appropriately. But we are still concerned about the risk of over regulation and the quick application of simplistic solutions to intricate problems. Every system can be improved, and we support and applaud well thought out improvements by regulators, legislators and industry representatives that achieve the common goal of building and protecting the value of investors’ holdings.

For nearly 60 years, Fidelity has worked very hard to improve its products and service to justify your trust. When our family founded this company in 1946, we had only a few hundred customers. Today, we serve more than 18 million customers including individual investors and participants in retirement plans across America.

Let me close by saying that we do not take your trust in us for granted, and we realize that we must always work to improve all aspects of our service to you. In turn, we urge you to continue your active participation with your financial matters, so that your interests can be well served.

Best regards,

/s/ Edward C. Johnson 3d

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemption proceeds, redemption fees, and (2) ongoing costs, including management fees, distribution and/or service (12b 1) 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 (August 1, 2005 to January 31, 2006).

Actual Expenses

The first line of the table below 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.

Hypothetical Example for Comparison Purposes

The second line of the table below 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 informa tion 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.

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.

1. Significant Accounting Policies.

Fidelity Small Cap Growth Fund (the fund) is a non diversified fund of Fidelity Securi ties Fund (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 Class A, Class T, Class B, Class C, Small Cap Growth, and Institutional Class 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. Class B shares will automatically convert to Class A shares after a holding period of seven years from the initial date of purchase. 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 and distribution and service plan fees incurred. Certain expense reductions also differ by class.

The fund may invest in affiliated money market central funds (Money Market Central Funds) which are open end investment companies available to investment companies and other accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require manage ment to make certain estimates and assumptions at the date of the financial statements. The following summarizes the significant accounting policies of the fund:

Security Valuation. Investments are valued and net asset value (NAV) per share is calculated (NAV calculation) as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time. Wherever possible, the fund uses independent pricing services approved by the Board of Trustees to value its investments.

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 an independent pricing service on the primary market or exchange on which they are traded. 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. Investments in open end mutual funds, are valued at their closing net asset value each business day. Short term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued at amortized cost, which approximates value.

When current market prices or quotations are not readily available or do not accurately reflect fair value, valuations may be determined in accordance with procedures adopted by the Board of Trustees. For example, when developments occur between the close of a

Security Valuation continued
 
   

market and the close of the NYSE that may materially affect the value of some or all of the securities, or when trading in a security is halted, those securities may be fair valued. Factors used in the determination of fair value may include monitoring news to identify significant market or security specific events such as changes in the value of U.S. securi ties markets, reviewing developments in foreign markets and evaluating the perfor mance of ADRs, futures contracts and exchange traded funds. Because the fund’s utilization of fair value pricing depends on market activity, the frequency with which fair value pricing is used can not be predicted and may be utilized to a significant extent. The value of securities used for NAV calculation under fair value pricing may differ from published prices for the same securities.

Foreign Currency. The fund uses foreign currency contracts to facilitate transactions in foreign denominated securities. 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 trans lated into U.S. dollars at the exchange rate at period end. Purchases and sales of invest ment 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 transac tion 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. Security transactions are accounted for as of trade date. Gains and losses on securities sold are determined on the basis of identified cost. 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 esti mates the components of distributions received that may be considered return of capital distributions or capital gain distributions. Large, non recurring dividends recognized by the fund are presented separately on the Statement of Operations as “Special Dividends” and the impact of these dividends is presented in the Financial Highlights. Interest income is 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.

1. Significant Accounting Policies continued
 

Expenses. Most expenses of the trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among each fund in the trust.

Income Tax Information and Distributions to Shareholders. Each year, the fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements. 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 recorded on the ex dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distribu tions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. In addition, the fund claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

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, passive foreign investment companies (PFIC) and losses deferred due to wash sales.

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

Unrealized appreciation      $  54,447,942 
Unrealized depreciation        (7,058,875) 
Net unrealized appreciation (depreciation)      $  47,389,067 
Cost for federal income tax purposes      $  355,922,308 

Short Term Trading (Redemption) Fees. Shares held in the fund less than 90 days are subject to a redemption fee equal to 1.50% of the proceeds of the redeemed shares. All redemption fees, including any estimated redemption fees paid by FMR, are retained by the fund and accounted for as an addition to paid in capital.

2. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits the fund and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. The fund may also invest directly with institutions in repurchase agreements. Repurchase agreements are collateralized by government or non government securities. Collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default of the counterparty. The fund monitors, on a daily basis, the value of the collateral to ensure it is at least equal to

Repurchase Agreements continued

the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

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 transac tions 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.

3. Purchases and Sales of Investments.

Purchases and sales of securities, other than short term securities and U.S. government securities, aggregated $266,055,748 and $128,949,824, respectively.

4. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the fund with investment manage ment related services for which the fund pays a monthly management fee. The manage ment 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 a group fee rate that averaged .27% 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 investment performance of the asset weighted return of Small Cap Growth (the original class) as compared to an appropriate bench mark index. The fund’s performance adjustment took effect in November 2005. Subse quent months will be added until the performance period includes 36 months. For the period, the total annualized management fee rate, including the performance adjust ment, was .78% of the fund’s average net assets.

Distribution and Service Plan. In accordance with Rule 12b 1 of the 1940 Act, the fund has adopted separate Distribution and Service Plans for each class of shares. Certain classes pay Fidelity Distributors Corporation (FDC), an affiliate of FMR, separate Distribution and Service Fees, each of which is based on an annual percentage of each class’ average net assets. In addition, FDC may pay financial intermediaries for selling

    Distribution    Service        Paid to        Retained 
    Fee    Fee        FDC        by FDC

              $  91,254      $  34,254 

Sales Load. FDC receives a front end sales charge of up to 5.75% for selling Class A shares, and 3.50% for selling Class T shares, some of which is paid to financial intermedi aries for selling shares of the fund. FDC receives the proceeds of contingent deferred sales charges levied on Class A, Class T, Class B, and Class C redemptions. These charges depend on the holding period. The deferred sales charges range from 5% to 1% for Class B, 1% for Class C, and .25% for certain purchases of Class A and Class T shares.

For the period, sales charge amounts retained by FDC were as follows:
 
   
        Retained 
        by FDC 
Class A      $  25,490 
Class T        4,084 
Class B*        889 
Class C*        1,015 
      $  31,478 

* When Class B and Class C shares are initially sold, FDC pays commissions from its own resources to financial intermediaries through which the sales are made.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of FMR, is the transfer, dividend disbursing and shareholder servic ing agent for each class of the fund, except for Small Cap Growth. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, is the transfer agent for Small Cap Growth shares. FIIOC and FSC receive account fees and asset based fees that vary according to the account size and type of account of the shareholders of the respective classes of the fund. FIIOC and FSC pay for typesetting, printing and mailing of shareholder reports,

      $  272,923     
* Annualized             

Accounting and Security Lending Fees. FSC maintains the fund’s accounting rec ords. The accounting fee is based on the level of average net assets for the 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.

Affiliated Central Funds. The fund may invest in Money Market Central Funds which seek preservation of capital and current income and are managed by Fidelity Invest ments Money Management, Inc. (FIMM), an affiliate of FMR.

The Money Market Central Funds do not pay a management fee.

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 $13,964 for the period.

5. Committed Line of Credit.

The fund participates with other funds managed by FMR in a $4.2 billion credit facility (the “line of credit”) to be utilized for temporary or emergency purposes to fund share holder 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. During the period, there were no borrowings on this line of credit.

29 Semiannual Report

Notes to Financial Statements (Unaudited)  continued 

6. Security Lending.
 
   

The fund lends portfolio securities from time to time in order to earn additional income. 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. Security lending income represents the income earned on investing cash collateral, less fees and expenses associated with the loan, plus any premium payments that may be received on the loan of certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from affiliated central funds. Net income from lending portfolio securities during the period amounted to $12,921.

7. Expense Reductions.

FMR voluntarily agreed to reimburse each class to the extent annual operating expenses exceeded certain levels of average net assets as noted in the table below. Some expenses, for example interest expense, are excluded from this reimbursement.

The following classes were in reimbursement during the period:
 
       
    Expense        Reimbursement 
    Limitations        from adviser 
Class A    1.40%      $  5,183 
Class T    1.65%        4,337 
Class B    2.15%        1,771 
Class C    2.15%        4,376 
          $  15,667 

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 $103,072 for the period. In addition, through arrangements with the fund’s custodian and each class’ transfer agent, 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 $1,801. During

the period, credits reduced each class’ transfer agent expense as noted in the table below.

    Transfer Agent 
    expense reduction 
Small Cap Growth     $    109 
Institutional Class        452 
     $    561 
 
 
8. 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.

9. Distributions to Shareholders.             
 
Distributions to shareholders of each class were as follows:

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Small Cap Growth Fund

On January 19, 2006, the Board of Trustees, including the Independent Trustees (together, the Board), voted to approve a general research services agreement (the Agreement) between FMR, FMR Co., Inc. (FMRC), Fidelity Investments Money Manage ment, Inc. (FIMM), and Fidelity Research & Analysis Company (FRAC) (together, the Investment Advisers) for the fund, effective January 20, 2006, pursuant to which FRAC may provide general research and investment advisory support services to FMRC and FIMM. The Board considered that it has approved previously various sub advisory agreements for the fund with affiliates of FMR that allow FMR to obtain research, non discretionary advice, or discretionary portfolio management at no additional expense to the fund. The Board, assisted by the advice of fund counsel and independent Trustees’ counsel, considered a broad range of information and determined that it would be beneficial for the fund to access the research and investment advisory support services supplied by FRAC at no additional expense to the fund.

The Board reached this determination in part because the new arrangement will involve no changes in (i) the contractual terms of and fees payable under the fund’s manage ment contract or sub advisory agreements; (ii) the investment process or strategies employed in the management of the fund’s assets; (iii) the nature or level of services provided under the fund’s management contract or sub advisory agreements; (iv) the day to day management of the fund or the persons primarily responsible for such man agement; or (v) the ultimate control or beneficial ownership of FMR, FMRC, or FIMM. The Board also considered that the establishment of the Agreement would not necessi tate prior shareholder approval of the Agreement or result in an assignment and termination of the fund’s management contract or sub advisory agreements under the Investment Company Act of 1940.

Because the Board was approving an arrangement with FRAC under which the fund will not bear any additional management fees or expenses and under which the fund’s portfolio manager would not change, it did not consider the fund’s investment perfor mance, competitiveness of management fee and total expenses, costs of services and profitability, or economies of scale to be significant factors in its decision.

In connection with its future renewal of the fund’s management contract and sub advisory agreements, the Board will consider: (i) the nature, extent, and quality of services provided to the fund, including shareholder and administrative services and investment performance; (ii) the competitiveness of the fund’s management fee and total expenses; (iii) the costs of the services and profitability, including 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; and (iv) 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.

Based on its evaluation of all of the conclusions noted above, and after considering all material factors, the Board ultimately concluded that the fund’s Agreement is fair and reasonable, and that the fund’s Agreement should be approved.

Chairman’s Message

(photograph of Edward C. Johnson 3d)

Dear Shareholder:

During the past year or so, much has been reported about the mutual fund industry, and much of it has been more critical than I believe is warranted. Allegations that some companies have been less than forthright with their shareholders have cast a shadow on the entire industry. I continue to find these reports disturbing, and assert that they do not create an accurate picture of the industry overall. Therefore, I would like to remind every one where Fidelity stands on these issues. I will say two things specifically regarding allegations that some mutual fund companies were in violation of the Securities and Exchange Commission’s forward pricing rules or were involved in so called “market timing” activities.

First, Fidelity has no agreements that permit customers who buy fund shares after 4 p.m. to obtain the 4 p.m. price. This is not a new policy. This is not to say that some one could not deceive the company through fraudulent acts. However, we are extremely diligent in preventing fraud from occurring in this manner and in every other. But I underscore again that Fidelity has no so called “agreements” that sanction illegal practices.

Second, Fidelity continues to stand on record, as we have for years, in opposition to predatory short term trading that adversely affects shareholders in a mutual fund. Back in the 1980s, we initiated a fee which is returned to the fund and, therefore, to investors to discourage this activity. Further, we took the lead several years ago in developing a Fair Value Pricing Policy to prevent market timing on foreign securities in our funds. I am confident we will find other ways to make it more difficult for predatory traders to operate. However, this will only be achieved through close cooperation among regulators, legislators and the industry.

Yes, there have been unfortunate instances of unethical and illegal activity within the mutual fund industry from time to time. That is true of any industry. When this occurs, confessed or convicted offenders should be dealt with appropriately. But we are still concerned about the risk of over regulation and the quick application of simplistic solutions to intricate problems. Every system can be improved, and we support and applaud well thought out improvements by regulators, legislators and industry representatives that achieve the common goal of building and protecting the value of investors’ holdings.

For nearly 60 years, Fidelity has worked very hard to improve its products and service to justify your trust. When our family founded this company in 1946, we had only a few hundred customers. Today, we serve more than 18 million customers including individual investors and participants in retirement plans across America.

Let me close by saying that we do not take your trust in us for granted, and we realize that we must always work to improve all aspects of our service to you. In turn, we urge you to continue your active participation with your financial matters, so that your interests can be well served.

Best regards,

/s/ Edward C. Johnson 3d

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemption proceeds, redemption fees, and (2) ongoing costs, including management fees, distribution and/or service (12b 1) 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 (August 1, 2005 to January 31, 2006).

Actual Expenses

The first line of the table below 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.

Hypothetical Example for Comparison Purposes

The second line of the table below 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 informa tion 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.

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 January 31, 2006 (Unaudited)

1. Significant Accounting Policies.

Fidelity Small Cap Growth Fund (the fund) is a non diversified fund of Fidelity Securi ties Fund (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 Class A, Class T, Class B, Class C, Small Cap Growth, and Institutional Class 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. Class B shares will automatically convert to Class A shares after a holding period of seven years from the initial date of purchase. 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 and distribution and service plan fees incurred. Certain expense reductions also differ by class.

The fund may invest in affiliated money market central funds (Money Market Central Funds) which are open end investment companies available to investment companies and other accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require manage ment to make certain estimates and assumptions at the date of the financial statements. The following summarizes the significant accounting policies of the fund:

Security Valuation. Investments are valued and net asset value (NAV) per share is calculated (NAV calculation) as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time. Wherever possible, the fund uses independent pricing services approved by the Board of Trustees to value its investments.

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 an independent pricing service on the primary market or exchange on which they are traded. 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. Investments in open end mutual funds, are valued at their closing net asset value each business day. Short term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued at amortized cost, which approximates value.

When current market prices or quotations are not readily available or do not accurately reflect fair value, valuations may be determined in accordance with procedures adopted by the Board of Trustees. For example, when developments occur between the close of a

Security Valuation continued
 
   

market and the close of the NYSE that may materially affect the value of some or all of the securities, or when trading in a security is halted, those securities may be fair valued. Factors used in the determination of fair value may include monitoring news to identify significant market or security specific events such as changes in the value of U.S. securi ties markets, reviewing developments in foreign markets and evaluating the perfor mance of ADRs, futures contracts and exchange traded funds. Because the fund’s utilization of fair value pricing depends on market activity, the frequency with which fair value pricing is used can not be predicted and may be utilized to a significant extent. The value of securities used for NAV calculation under fair value pricing may differ from published prices for the same securities.

Foreign Currency. The fund uses foreign currency contracts to facilitate transactions in foreign denominated securities. 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 rate at period end. Purchases and sales of invest ment 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. Security transactions are accounted for as of trade date. Gains and losses on securities sold are determined on the basis of identified cost. 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 esti mates the components of distributions received that may be considered return of capital distributions or capital gain distributions. Large, non recurring dividends recognized by the fund are presented separately on the Statement of Operations as “Special Dividends” and the impact of these dividends is presented in the Financial Highlights. Interest income is 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.

Notes to Financial Statements (Unaudited) continued 

1. Significant Accounting Policies continued
 

Expenses. Most expenses of the trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among each fund in the trust.

Income Tax Information and Distributions to Shareholders. Each year, the fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements. 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 recorded on the ex dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distribu tions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. In addition, the fund claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

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, passive foreign investment companies (PFIC) and losses deferred due to wash sales.

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

Unrealized appreciation      $  54,447,942 
Unrealized depreciation        (7,058,875) 
Net unrealized appreciation (depreciation)      $  47,389,067 
Cost for federal income tax purposes      $  355,922,308 

Short Term Trading (Redemption) Fees. Shares held in the fund less than 90 days are subject to a redemption fee equal to 1.50% of the proceeds of the redeemed shares. All redemption fees, including any estimated redemption fees paid by FMR, are retained by the fund and accounted for as an addition to paid in capital.

2. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits the fund and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. The fund may also invest directly with institutions in repurchase agreements. Repurchase agreements are collateralized by government or non government securities. Collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default of the counterparty. The fund monitors, on a daily basis, the value of the collateral to ensure it is at least equal to

Repurchase Agreements continued

the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

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 transac tions 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.

3. Purchases and Sales of Investments.

Purchases and sales of securities, other than short term securities and U.S. government securities, aggregated $266,055,748 and $128,949,824, respectively.

4. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the fund with investment manage ment related services for which the fund pays a monthly management fee. The manage ment 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 a group fee rate that averaged .27% 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 investment performance of the asset weighted return of Small Cap Growth (the original class) as compared to an appropriate bench mark index. The fund’s performance adjustment took effect in November 2005. Subse quent months will be added until the performance period includes 36 months. For the period, the total annualized management fee rate, including the performance adjust ment, was .78% of the fund’s average net assets.

Distribution and Service Plan. In accordance with Rule 12b 1 of the 1940 Act, the fund has adopted separate Distribution and Service Plans for each class of shares. Certain classes pay Fidelity Distributors Corporation (FDC), an affiliate of FMR, separate Distribution and Service Fees, each of which is based on an annual percentage of each class’ average net assets. In addition, FDC may pay financial intermediaries for selling

Accounting and Security Lending Fees. FSC maintains the fund’s accounting records. The accounting fee is based on the level of average net assets for the 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.

Affiliated Central Funds. The fund may invest in Money Market Central Funds which seek preservation of capital and current income and are managed by Fidelity Invest ments Money Management, Inc. (FIMM), an affiliate of FMR.

The Money Market Central Funds do not pay a management fee.

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 $13,964 for the period.

5. Committed Line of Credit.

The fund participates with other funds managed by FMR in a $4.2 billion credit facility (the “line of credit”) to be utilized for temporary or emergency purposes to fund share holder 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. During the period, there were no borrowings on this line of credit.

6. Security Lending.
 
   

The fund lends portfolio securities from time to time in order to earn additional income. 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. Security lending income represents the income earned on investing cash collateral, less fees and expenses associated with the loan, plus any premium payments that may be received on the loan of certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from affiliated central funds. Net income from lending portfolio securities during the period amounted to $12,921.

7. Expense Reductions.

FMR voluntarily agreed to reimburse each class to the extent annual operating expenses exceeded certain levels of average net assets as noted in the table below. Some expenses, for example interest expense, are excluded from this reimbursement.

The following classes were in reimbursement during the period:
 
       
    Expense        Reimbursement 
    Limitations        from adviser 
Class A    1.40%      $  5,183 
Class T    1.65%        4,337 
Class B    2.15%        1,771 
Class C    2.15%        4,376 
          $  15,667 

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 $103,072 for the period. In addition, through arrangements with the fund’s custodian and each class’ transfer agent, 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 $1,801. During

8. 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 consid ered remote.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Small Cap Growth Fund

On January 19, 2006, the Board of Trustees, including the Independent Trustees (together, the Board), voted to approve a general research services agreement (the Agreement) between FMR, FMR Co., Inc. (FMRC), Fidelity Investments Money Manage ment, Inc. (FIMM), and Fidelity Research & Analysis Company (FRAC) (together, the Investment Advisers) for the fund, effective January 20, 2006, pursuant to which FRAC may provide general research and investment advisory support services to FMRC and FIMM. The Board considered that it has approved previously various sub advisory agreements for the fund with affiliates of FMR that allow FMR to obtain research, non discretionary advice, or discretionary portfolio management at no additional expense to the fund. The Board, assisted by the advice of fund counsel and independent Trustees’ counsel, considered a broad range of information and determined that it would be beneficial for the fund to access the research and investment advisory support services supplied by FRAC at no additional expense to the fund.

The Board reached this determination in part because the new arrangement will involve no changes in (i) the contractual terms of and fees payable under the fund’s manage ment contract or sub advisory agreements; (ii) the investment process or strategies employed in the management of the fund’s assets; (iii) the nature or level of services provided under the fund’s management contract or sub advisory agreements; (iv) the day to day management of the fund or the persons primarily responsible for such man agement; or (v) the ultimate control or beneficial ownership of FMR, FMRC, or FIMM. The Board also considered that the establishment of the Agreement would not necessi tate prior shareholder approval of the Agreement or result in an assignment and termination of the fund’s management contract or sub advisory agreements under the Investment Company Act of 1940.

Because the Board was approving an arrangement with FRAC under which the fund will not bear any additional management fees or expenses and under which the fund’s portfolio manager would not change, it did not consider the fund’s investment perfor mance, competitiveness of management fee and total expenses, costs of services and profitability, or economies of scale to be significant factors in its decision.

In connection with its future renewal of the fund’s management contract and sub advisory agreements, the Board will consider: (i) the nature, extent, and quality of services provided to the fund, including shareholder and administrative services and investment performance; (ii) the competitiveness of the fund’s management fee and total expenses; (iii) the costs of the services and profitability, including 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; and (iv) whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have

Board Approval of Investment Advisory Contracts and Management Fees continued

appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies.

Based on its evaluation of all of the conclusions noted above, and after considering all material factors, the Board ultimately concluded that the fund’s Agreement is fair and reasonable, and that the fund’s Agreement should be approved.

Chairman’s Message

(photograph of Edward C. Johnson 3d)

Dear Shareholder:

During the past year or so, much has been reported about the mutual fund industry, and much of it has been more critical than I believe is warranted. Allegations that some companies have been less than forthright with their shareholders have cast a shadow on the entire industry. I continue to find these reports disturbing, and assert that they do not create an accurate picture of the industry overall. Therefore, I would like to remind every one where Fidelity stands on these issues. I will say two things specifically regarding allegations that some mutual fund companies were in violation of the Securities and Exchange Commission’s forward pricing rules or were involved in so called “market timing” activities.

First, Fidelity has no agreements that permit customers who buy fund shares after 4 p.m. to obtain the 4 p.m. price. This is not a new policy. This is not to say that some one could not deceive the company through fraudulent acts. However, we are extremely diligent in preventing fraud from occurring in this manner and in every other. But I underscore again that Fidelity has no so called “agreements” that sanction illegal practices.

Second, Fidelity continues to stand on record, as we have for years, in opposition to predatory short term trading that adversely affects shareholders in a mutual fund. Back in the 1980s, we initiated a fee which is returned to the fund and, therefore, to investors to discourage this activity. Further, we took the lead several years ago in developing a Fair Value Pricing Policy to prevent market timing on foreign securities in our funds. I am confident we will find other ways to make it more difficult for predatory traders to operate. However, this will only be achieved through close cooperation among regulators, legislators and the industry.

Yes, there have been unfortunate instances of unethical and illegal activity within the mutual fund industry from time to time. That is true of any industry. When this occurs, confessed or convicted offenders should be dealt with appropriately. But we are still concerned about the risk of over regulation and the quick application of simplistic solutions to intricate problems. Every system can be improved, and we support and applaud well thought out improvements by regulators, legislators and industry representatives that achieve the common goal of building and protecting the value of investors’ holdings.

For nearly 60 years, Fidelity has worked very hard to improve its products and service to justify your trust. When our family founded this company in 1946, we had only a few hundred customers. Today, we serve more than 18 million customers including individual investors and participants in retirement plans across America.

Let me close by saying that we do not take your trust in us for granted, and we realize that we must always work to improve all aspects of our service to you. In turn, we urge you to continue your active participation with your financial matters, so that your interests can be well served.

Best regards,

/s/ Edward C. Johnson 3d

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemption proceeds, redemption fees, and (2) ongoing costs, including management fees, distribution and/or service (12b 1) 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 (August 1, 2005 to January 31, 2006).

Actual Expenses

The first line of the table below 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.

Hypothetical Example for Comparison Purposes

The second line of the table below 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 informa tion 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.

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 January 31, 2006 (Unaudited)

1. Significant Accounting Policies.

Fidelity Small Cap Growth Fund (the fund) is a non diversified fund of Fidelity Securi ties Fund (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 Class A, Class T, Class B, Class C, Small Cap Growth, and Institutional Class 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. Class B shares will automatically convert to Class A shares after a holding period of seven years from the initial date of purchase. 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 and distribution and service plan fees incurred. Certain expense reductions also differ by class.

The fund may invest in affiliated money market central funds (Money Market Central Funds) which are open end investment companies available to investment companies and other accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require manage ment to make certain estimates and assumptions at the date of the financial statements. The following summarizes the significant accounting policies of the fund:

Security Valuation. Investments are valued and net asset value (NAV) per share is calculated (NAV calculation) as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time. Wherever possible, the fund uses independent pricing services approved by the Board of Trustees to value its investments.

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 an independent pricing service on the primary market or exchange on which they are traded. 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. Investments in open end mutual funds, are valued at their closing net asset value each business day. Short term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued at amortized cost, which approximates value.

When current market prices or quotations are not readily available or do not accurately reflect fair value, valuations may be determined in accordance with procedures adopted by the Board of Trustees. For example, when developments occur between the close of a

Security Valuation continued
 
   

market and the close of the NYSE that may materially affect the value of some or all of the securities, or when trading in a security is halted, those securities may be fair valued. Factors used in the determination of fair value may include monitoring news to identify significant market or security specific events such as changes in the value of U.S. securi ties markets, reviewing developments in foreign markets and evaluating the perfor mance of ADRs, futures contracts and exchange traded funds. Because the fund’s utilization of fair value pricing depends on market activity, the frequency with which fair value pricing is used can not be predicted and may be utilized to a significant extent. The value of securities used for NAV calculation under fair value pricing may differ from published prices for the same securities.

Foreign Currency. The fund uses foreign currency contracts to facilitate transactions in foreign denominated securities. 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 trans lated into U.S. dollars at the exchange rate at period end. Purchases and sales of invest ment 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 transac tion 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. Security transactions are accounted for as of trade date. Gains and losses on securities sold are determined on the basis of identified cost. 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 esti mates the components of distributions received that may be considered return of capital distributions or capital gain distributions. Large, non recurring dividends recognized by the fund are presented separately on the Statement of Operations as “Special Dividends” and the impact of these dividends is presented in the Financial Highlights. Interest income is 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.

1. Significant Accounting Policies continued
 

Expenses. Most expenses of the trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among each fund in the trust.

Income Tax Information and Distributions to Shareholders. Each year, the fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements. 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 recorded on the ex dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distribu tions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. In addition, the fund claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

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, passive foreign investment companies (PFIC) and losses deferred due to wash sales.

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

Short Term Trading (Redemption) Fees. Shares held in the fund less than 90 days are subject to a redemption fee equal to 1.50% of the proceeds of the redeemed shares. All redemption fees, including any estimated redemption fees paid by FMR, are retained by the fund and accounted for as an addition to paid in capital.

2. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits the fund and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. The fund may also invest directly with institutions in repurchase agreements. Repurchase agreements are collateralized by government or non government securities. Collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default of the counterparty. The fund monitors, on a daily basis, the value of the collateral to ensure it is at least equal to

Repurchase Agreements continued

the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

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 transac tions 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.

3. Purchases and Sales of Investments.

Purchases and sales of securities, other than short term securities and U.S. government securities, aggregated $266,055,748 and $128,949,824, respectively.

4. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the fund with investment manage ment related services for which the fund pays a monthly management fee. The manage ment 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 a group fee rate that averaged .27% 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 investment performance of the asset weighted return of Small Cap Growth (the original class) as compared to an appropriate bench mark index. The fund’s performance adjustment took effect in November 2005. Subse quent months will be added until the performance period includes 36 months. For the period, the total annualized management fee rate, including the performance adjust ment, was .78% of the fund’s average net assets.

Distribution and Service Plan. In accordance with Rule 12b 1 of the 1940 Act, the fund has adopted separate Distribution and Service Plans for each class of shares. Certain classes pay Fidelity Distributors Corporation (FDC), an affiliate of FMR, separate Distribution and Service Fees, each of which is based on an annual percentage of each class’ average net assets. In addition, FDC may pay financial intermediaries for selling

              $  91,254      $  34,254 

Sales Load. FDC receives a front end sales charge of up to 5.75% for selling Class A shares, and 3.50% for selling Class T shares, some of which is paid to financial intermedi aries for selling shares of the fund. FDC receives the proceeds of contingent deferred sales charges levied on Class A, Class T, Class B, and Class C redemptions. These charges depend on the holding period. The deferred sales charges range from 5% to 1% for Class B, 1% for Class C, and .25% for certain purchases of Class A and Class T shares.

For the period, sales charge amounts retained by FDC were as follows:

 
   
        Retained 
        by FDC 
Class A      $  25,490 
Class T        4,084 
Class B*        889 
Class C*        1,015 
      $  31,478 

* When Class B and Class C shares are initially sold, FDC pays commissions from its own resources to financial intermediaries through which the sales are made.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of FMR, is the transfer, dividend disbursing and shareholder servic ing agent for each class of the fund, except for Small Cap Growth. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, is the transfer agent for Small Cap Growth shares. FIIOC and FSC receive account fees and asset based fees that vary according to the account size and type of account of the shareholders of the respective classes of the fund. FIIOC and FSC pay for typesetting, printing and mailing of shareholder reports,

Accounting and Security Lending Fees. FSC maintains the fund’s accounting rec ords. The accounting fee is based on the level of average net assets for the 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.

Affiliated Central Funds. The fund may invest in Money Market Central Funds which seek preservation of capital and current income and are managed by Fidelity Invest ments Money Management, Inc. (FIMM), an affiliate of FMR.

The Money Market Central Funds do not pay a management fee.

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 $13,964 for the period.

5. Committed Line of Credit.

The fund participates with other funds managed by FMR in a $4.2 billion credit facility (the “line of credit”) to be utilized for temporary or emergency purposes to fund share holder 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. During the period, there were no borrowings on this line of credit.

6. Security Lending.
 
   

The fund lends portfolio securities from time to time in order to earn additional income. 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. Security lending income represents the income earned on investing cash collateral, less fees and expenses associated with the loan, plus any premium payments that may be received on the loan of certain types of securities. Security lending income is presented in the Statement of Operations as a component of income from affiliated central funds. Net income from lending portfolio securities during the period amounted to $12,921.

7. Expense Reductions.

FMR voluntarily agreed to reimburse each class to the extent annual operating expenses exceeded certain levels of average net assets as noted in the table below. Some expenses, for example interest expense, are excluded from this reimbursement.

The following classes were in reimbursement during the period:
 
       
    Expense        Reimbursement 
    Limitations        from adviser 
Class A    1.40%      $  5,183 
Class T    1.65%        4,337 
Class B    2.15%        1,771 
Class C    2.15%        4,376 
          $  15,667 

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 $103,072 for the period. In addition, through arrangements with the fund’s custodian and each class’ transfer agent, 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 $1,801. During

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.

Distributions to shareholders of each class were as follows:

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Small Cap Growth Fund

On January 19, 2006, the Board of Trustees, including the Independent Trustees (together, the Board), voted to approve a general research services agreement (the Agreement) between FMR, FMR Co., Inc. (FMRC), Fidelity Investments Money Manage ment, Inc. (FIMM), and Fidelity Research & Analysis Company (FRAC) (together, the Investment Advisers) for the fund, effective January 20, 2006, pursuant to which FRAC may provide general research and investment advisory support services to FMRC and FIMM. The Board considered that it has approved previously various sub advisory agreements for the fund with affiliates of FMR that allow FMR to obtain research, non discretionary advice, or discretionary portfolio management at no additional expense to the fund. The Board, assisted by the advice of fund counsel and independent Trustees’ counsel, considered a broad range of information and determined that it would be beneficial for the fund to access the research and investment advisory support services supplied by FRAC at no additional expense to the fund.

The Board reached this determination in part because the new arrangement will involve no changes in (i) the contractual terms of and fees payable under the fund’s manage ment contract or sub advisory agreements; (ii) the investment process or strategies employed in the management of the fund’s assets; (iii) the nature or level of services provided under the fund’s management contract or sub advisory agreements; (iv) the day to day management of the fund or the persons primarily responsible for such man agement; or (v) the ultimate control or beneficial ownership of FMR, FMRC, or FIMM. The Board also considered that the establishment of the Agreement would not necessi tate prior shareholder approval of the Agreement or result in an assignment and termination of the fund’s management contract or sub advisory agreements under the Investment Company Act of 1940.

Because the Board was approving an arrangement with FRAC under which the fund will not bear any additional management fees or expenses and under which the fund’s portfolio manager would not change, it did not consider the fund’s investment perfor mance, competitiveness of management fee and total expenses, costs of services and profitability, or economies of scale to be significant factors in its decision.

In connection with its future renewal of the fund’s management contract and sub advisory agreements, the Board will consider: (i) the nature, extent, and quality of services provided to the fund, including shareholder and administrative services and investment performance; (ii) the competitiveness of the fund’s management fee and total expenses; (iii) the costs of the services and profitability, including 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; and (iv) 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.

Based on its evaluation of all of the conclusions noted above, and after considering all material factors, the Board ultimately concluded that the fund’s Agreement is fair and reasonable, and that the fund’s Agreement should be approved.
