     helps compare the cost of investing in the fund with the cost of investing in other funds.

     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. This example does not include any fees or other expenses of any variable annuity or variable life insurance product; if it did, overall expenses would be higher. For every $10,000 invested, here's how much you, as a variable product owner, would pay in total expenses if all interests in a separate account that invests in shares of the fund were redeemed at the end of each time period indicated:

      Normally investing primarily in common stocks.



        Normally investing at least 80% of assets in securities of companies principally engaged in the development, production, or distribution of communication services.



     These companies may include, for example, interactive media and services including search engines, social media and networking platforms; companies that produce and sell entertainment and media such as movies, TV, cable, radio, internet and satellite companies; interactive gaming and home entertainment products and services; advertising; publishing and public relations companies; operators of fixed-line telecommunications networks and companies; providers of cellular or wireless communications services and equipment; and providers of communications and high-density data transmission services and equipment.
     For purposes of the fund's policy to normally invest at least 80% of its assets in securities of companies principally engaged in the business activity or activities identified for the fund, Fidelity may consider a company to be principally engaged in the designated business activity or activities based on: (i) the level of a company's assets, income, sales, or profits that are committed to, derived from, or related to the designated business activity or activities, or (ii) whether a third party has given the company an industry or sector classification consistent with the designated business activity or activities. Whether a company is principally engaged in the designated business activity or activities can be determined under any of these factors.
     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.

     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.

     helps compare the cost of investing in the fund with the cost of investing in other funds.

     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. This example does not include any fees or other expenses of any variable annuity or variable life insurance product; if it did, overall expenses would be higher. For every $10,000 invested, here's how much you, as a variable product owner, would pay in total expenses if all interests in a separate account that invests in shares of the fund were redeemed at the end of each time period indicated:

      Normally investing primarily in common stocks.



        Normally investing at least 80% of assets in securities of companies principally engaged in the research, development, manufacture, distribution, supply, or sale of industrial products, services, or equipment.



     These companies may include, for example, manufacturers of civil or military aerospace and defense equipment, building components, and home improvement products and equipment; civil engineering companies and large-scale contractors; companies that produce electrical components or equipment; manufacturers of industrial machinery and industrial components and products; manufacturers of agricultural machinery and equipment; providers of commercial printing services; companies providing business support services related to human capital management and office supplies, providers of commercial data processing and business outsourcing services, environmental and facilities maintenance; companies providing transportation services, including airlines, couriers, marine, road &amp; rail, and transportation infrastructure.
     For purposes of the fund's policy to normally invest at least 80% of its assets in securities of companies principally engaged in the business activity or activities identified for the fund, Fidelity may consider a company to be principally engaged in the designated business activity or activities based on: (i) the level of a company's assets, income, sales, or profits that are committed to, derived from, or related to the designated business activity or activities, or (ii) whether a third party has given the company an industry or sector classification consistent with the designated business activity or activities. Whether a company is principally engaged in the designated business activity or activities can be determined under any of these factors.
     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.

     example

     helps compare the cost of investing in the fund with the cost of investing in other funds.

     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. This example does not include any fees or other expenses of any variable annuity or variable life insurance product; if it did, overall expenses would be higher. For every $10,000 invested, here's how much you, as a variable product owner, would pay in total expenses if all interests in a separate account that invests in shares of the fund were redeemed at the end of each time period indicated:

      Normally investing primarily in common stocks.



        Normally investing at least 80% of assets in securities of companies principally engaged in the manufacture, mining, processing, or distribution of raw materials and intermediate goods.



     These companies may include, for example, manufacturers of sand, lime, concrete and other building materials, metal, glass, plastic, or cardboard containers or packaging; producers of industrial and basic chemicals, including plastics, synthetic fibers, and commodity-based paints and pigments; fertilizer and other agriculture-related chemical products; companies that produce adhesives, sealants, and other high value-added chemicals; producers of aluminum and related materials; companies engaged in producing and extracting metals and minerals; producers of gold, iron, steel, and companies mining precious metals and minerals; and manufacturers of timber, related wood products, and paper.
     For purposes of the fund's policy to normally invest at least 80% of its assets in securities of companies principally engaged in the business activity or activities identified for the fund, Fidelity may consider a company to be principally engaged in the designated business activity or activities based on: (i) the level of a company's assets, income, sales, or profits that are committed to, derived from, or related to the designated business activity or activities, or (ii) whether a third party has given the company an industry or sector classification consistent with the designated business activity or activities. Whether a company is principally engaged in the designated business activity or activities can be determined under any of these factors.
     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.

      Normally investing primarily in common stocks.



        Normally investing at least 80% of assets in securities of companies principally engaged in the utilities industry and companies deriving a majority of their revenues from their utility operations.



     These companies may include, for example, companies that produce electricity, including nuclear and non-nuclear facilities; companies that distribute and transmit natural and manufactured gas; water treatment and other utility companies;
       companies that operate as independent power producers, gas and power marketing and trading specialists and/or integrated energy merchants; and companies that engage in the generation and distribution of electricity using renewable sources.
     For purposes of the fund's policy to normally invest at least 80% of its assets in securities of companies principally engaged in the business activity or activities identified for the fund, Fidelity may consider a company to be principally engaged in the designated business activity or activities based on: (i) the level of a company's assets, income, sales, or profits that are committed to, derived from, or related to the designated business activity or activities, or (ii) whether a third party has given the company an industry or sector classification consistent with the designated business activity or activities. Whether a company is principally engaged in the designated business activity or activities can be determined under any of these factors.
     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.

     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.
