Let's say, hypothetically, that the annual return for shares of the fund is 5% and that the fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary.

Portfolio Turnover
The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 53% of the average value of its portfolio.
Principal Investment Strategies
  • Normally investing primarily in common stocks.
  • Normally investing at least 80% of assets in securities principally traded on NASDAQ® or an over-the-counter (OTC) market.
The Adviser defines NASDAQ® and OTC securities as securities principally traded on either the NASDAQ® exchange or the OTC market (a telephone or computer network that connects securities dealers), which may include equity or debt securities. These securities can be issued by companies of any size. However, the OTC market has more small and medium-sized companies than other markets.
Effective December 11, 2025, derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives.
  • Investing more than 25% of total assets in the technology sector.
  • Investing in domestic and foreign issuers.
  • Investing in either "growth" stocks or "value" stocks or both.
  • Using fundamental analysis of factors such as each issuer's financial condition and industry position, as well as market and economic conditions, to select investments.
Principal Investment Risks
  • Stock Market Volatility.
Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.
  • Foreign Exposure.
Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market.
  • Technology Industry Concentration.
The technology industries can be significantly affected by obsolescence of existing technology, short product cycles, falling prices and profits, competition from new market entrants, and general economic conditions.
  • Issuer-Specific Changes.
The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.
The value of securities of smaller issuers can be more volatile than that of larger issuers.
  • "Growth" Investing.
"Growth" stocks can perform differently from the market as a whole and other types of stocks and can be more volatile than other types of stocks.
  • "Value" Investing.
"Value" stocks can perform differently from the market as a whole and other types of stocks and can continue to be undervalued by the market for long periods of time.
In addition, the fund is classified as non-diversified under the Investment Company Act of 1940 (1940 Act), which means that it has the ability to invest a greater portion of assets in securities of a smaller number of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a more diversified fund.
An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You could lose money by investing in the fund.
Performance
The following information is intended to help you understand the risks of investing in the fund.
The information illustrates the changes in the performance of the fund's shares from year to year and compares the performance of the fund's shares to the performance of a securities market index and an additional index over various periods of time. The additional index has characteristics relevant to the fund's investment strategies. Index descriptions appear in the "Additional Index Information" section of the prospectus. Past performance (before and after taxes) is not an indication of future performance.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates, but do not reflect the impact of state or local taxes. Actual after-tax returns may differ depending on your individual circumstances. The after-tax returns shown are not relevant if you hold your shares in a retirement account or in another tax-deferred arrangement, such as an employee benefit plan (profit sharing, 401(k), or 403(b) plan). Return After Taxes on Distributions and Sale of Fund Shares may be higher than other returns for the same period due to a tax benefit of realizing a capital loss upon the sale of fund shares.

Portfolio Turnover
The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 53% of the average value of its portfolio.
Principal Investment Strategies

The Adviser defines NASDAQ® and OTC securities as securities principally traded on either the NASDAQ® exchange or the OTC market (a telephone or computer network that connects securities dealers), which may include equity or debt securities. These securities can be issued by companies of any size. However, the OTC market has more small and medium-sized companies than other markets.
Effective December 11, 2025, derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives.
  • Investing more than 25% of total assets in the technology sector.
  • Investing in domestic and foreign issuers.
  • Investing in either "growth" stocks or "value" stocks or both.
  • Using fundamental analysis of factors such as each issuer's financial condition and industry position, as well as market and economic conditions, to select investments.

  • Stock Market Volatility.
Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. Different parts of the market, including different market sectors, and different types of securities can react differently to these developments.
  • Foreign Exposure.
Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market.
  • Technology Industry Concentration.
The technology industries can be significantly affected by obsolescence of existing technology, short product cycles, falling prices and profits, competition from new market entrants, and general economic conditions.
  • Issuer-Specific Changes.
The value of an individual security or particular type of security can be more volatile than, and can perform differently from, the market as a whole.
The value of securities of smaller issuers can be more volatile than that of larger issuers.
  • "Growth" Investing.
"Growth" stocks can perform differently from the market as a whole and other types of stocks and can be more volatile than other types of stocks.
  • "Value" Investing.
"Value" stocks can perform differently from the market as a whole and other types of stocks and can continue to be undervalued by the market for long periods of time.
In addition, the fund is classified as non-diversified under the Investment Company Act of 1940 (1940 Act), which means that it has the ability to invest a greater portion of assets in securities of a smaller number of individual issuers than a diversified fund. As a result, changes in the market value of a single investment could cause greater fluctuations in share price than would occur in a more diversified fund.
An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. You could lose money by investing in the fund.

* The returns shown above are for Fidelity® OTC Portfolio, a class of shares of the fund that is not offered through this prospectus. Class A, Class M, Class C, Class I, and Class Z would have substantially similar annual returns to Fidelity® OTC Portfolio because the classes are invested in the same portfolio of securities. Class A's, Class M's, Class C's, Class I's, and Class Z's returns would differ from Fidelity® OTC Portfolio's returns only to the extent that the classes do not have the same expenses.
Average Annual Returns*
After-tax returns are calculated using the historical highest individual federal marginal income tax rates, but do not reflect the impact of state or local taxes. Actual after-tax returns may differ depending on your individual circumstances. The after-tax returns shown are not relevant if you hold your shares in a retirement account or in another tax-deferred arrangement, such as an employee benefit plan (profit sharing, 401(k), or 403(b) plan). Return After Taxes on Distributions and Sale of Fund Shares may be higher than other returns for the same period due to a tax benefit of realizing a capital loss upon the sale of fund shares.
