Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•U.S. equities gained for the 12 months ending July 31, 2024, driven by resilient corporate profits, a frenzy over generative artificial intelligence and the Federal Reserve's likely pivot to cutting interest rates later this year.

•Against this backdrop, security selection was the primary contributor to the fund's performance versus the benchmark for the fiscal year, especially within information technology. Picks in industrials also boosted the fund's relative performance. Also helping our relative result was an overweight in communication services, primarily within the media & entertainment industry.

•The top individual relative contributor by far was an overweight in Nvidia (+150%). The stock was the fund's biggest holding. A second notable relative contributor was an underweight in Apple (+14%). The company was among the fund's biggest holdings. Another notable relative contributor was a non-benchmark stake in Abercrombie & Fitch (+273%).

•In contrast, the biggest detractor from performance versus the benchmark was an overweight in consumer discretionary, especially within the consumer durables & apparel industry. Stock picks in consumer staples, primarily within the consumer staples distribution & retail industry, also hampered the fund's result, as did an underweight in information technology.

•The biggest individual relative detractor was an underweight in Broadcom (+82%). This was a position we established this period. The second-largest relative detractor was an overweight in Marvell Technology (+3%). The stock was one of our largest holdings. An overweight in Lululemon Athletica (-31%) also hurt.

•Notable changes in positioning include lower allocation to industrials.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, security selection was the primary contributor to the fund's performance versus the benchmark for the fiscal year, especially within industrials, where our stock picks in capital goods helped most. Stock choices in health care, primarily within the pharmaceuticals, biotechnology & life sciences industry, and consumer discretionary also boosted the fund's relative performance.

•The fund's non-benchmark stake in Vertiv Holdings (+227%) was the top individual relative contributor. The stock was not held at period end. The second-largest relative contributor was an overweight in FTAI Aviation (+253%). This period we increased our stake, and FTAI Aviation finished the fiscal year as one of our biggest holdings. Another notable relative contributor was our stake in Rover (+99%), a stock that was not held at period end.

•In contrast, the biggest detractors from performance versus the benchmark were overweight holdings in health care and energy. Picks in communication services also detracted from our relative result.

•The largest individual relative detractors were an overweight in agilon health (-64%) and a non-benchmark stake in Allegro MicroSystems (-51%). This period we increased our position in Allegro MicroSystems. Our stake in Abercrombie & Fitch (-20%) also detracted. This was an investment we established this period.

•Notable changes in positioning include increased exposure to the financials sector and a lower allocation to consumer staples.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, market selection was the primary detractor from the fund's performance versus the S&P 500® index for the fiscal year, especially an underweight in information technology, where an underweight in semiconductors & semiconductor equipment hurt most. Stock picking and an underweight in communication services, primarily within the media & entertainment industry, also hampered the fund's result, as did security selection in materials. Lastly, the fund's position in cash detracted.

•The largest individual relative detractor was an underweight in Nvidia (+150%). This period we increased our position in Nvidia. The stock was one of our biggest holdings. The second-largest relative detractor was an overweight in Boeing (-22%). The company was among the fund's biggest holdings. Another notable relative detractor was our non-benchmark stake in First Quantum Minerals (-58%).

•In contrast, the biggest contributor to performance versus the benchmark was stock picking in industrials, primarily within the capital goods industry. Picks in health care, especially within the health care equipment & services industry, also boosted relative performance. Also contributing to our result was an underweight in consumer discretionary, primarily within the automobiles & components industry.

•The top individual relative contributor was an overweight in General Electric (+88%). The company was among the fund's biggest holdings. The second-largest relative contributor this period was avoiding Tesla, a benchmark component that returned -13%. An overweight in Wells Fargo (+30%) also contributed. The company was one of our biggest holdings.

•Notable changes in positioning include increased exposure to information technology.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, security selection was the primary contributor to the fund's performance versus the benchmark, the Russell Midcap Index, for the fiscal year, led by information technology, where our picks in semiconductors & semiconductor equipment helped most. Picks in utilities and communication services, primarily within the media & entertainment industry, also boosted the fund's relative performance.

•The fund's non-benchmark stake in Nvidia gained about 151% and was the top individual relative contributor. The company was the fund's biggest holding at period end. The second-largest relative contributor was an overweight in Vistra (+187%). The company was among our biggest holdings. Another notable relative contributor was a non-benchmark stake in Meta Platforms (+49%), the fund's top holding this period.

•In contrast, the biggest detractor from performance versus the benchmark was stock selection in materials. Also hurting our result were an overweight in communication services, primarily within the media & entertainment industry, and an underweight in industrials.

•The largest individual relative detractor was an overweight in ON Semiconductor (-27%). The company was among the biggest holdings. A non-benchmark stake in Tesla returned about -31% and was a second notable relative detractor. The stock was not held at period end. Another notable relative detractor was an overweight in Boyd Gaming (-10%), which was among the fund's biggest holdings this period.

•Notable changes in positioning include decreased exposure to the health care sector and a higher allocation to utilities.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, security selection was the primary contributor to the fund's performance versus the NASDAQ Composite Index for the fiscal year, led by industrials, where our picks among capital goods stocks helped the most. Security selection in consumer discretionary and information technology also boosted the fund's relative performance.

•The top individual relative contributor was an underweight in Tesla (-13%), followed by a non-benchmark stake in Taiwan Semiconductor Manufacturing (+69%). The latter was among the fund's largest holdings. Out-of-benchmark exposure to Vertiv Holdings (+210%) was another plus.

•In contrast, the biggest detractor from performance versus the benchmark was stock picking in consumer staples. An overweight in energy and comparatively light exposure to the market-leading information technology sector hurt as well.

•The biggest individual relative detractor was an underweight in Broadcom (+82%). This was a stake we established this period. A larger-than-benchmark holding in Lululemon Athletica (-32%) further pressured relative performance, as did an outsized position in Marvell Technology (+3%), one of the fund's largest holdings.

•Notable changes in positioning include decreased exposure to the energy sector and a higher allocation to health care stocks.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, security selection was the primary contributor to the fund's performance versus the S&P 500® index for the fiscal year, especially within information technology. Stock picks in industrials and utilities also boosted the fund's relative performance, as did positioning in consumer discretionary.

•The fund's non-benchmark stake in Vertiv Holdings (201%) was the top individual relative contributor. We reduced our holding in the stock by period end. Other notable relative contributors included overweight positions in Vistra (+186%) and Nvidia (+150%). We trimmed our stake in Vistra but increased it in Nvidia, and the latter was the fund's largest holding at the end of the fiscal year.

•In contrast, the biggest detractors from performance versus the benchmark were: positioning in communication services, particularly within the media & entertainment industry; an underweight in information technology; and overweights in energy and utilities.

•The largest individual relative detractor was our overweight stake in Boeing (-20%), which was among the fund's largest holdings this period. Untimely positioning in Meta Platforms (+50%) and avoiding Amazon.com (+40%) also hurt. We increased our stakes in Boeing and Meta Platforms during the period.

•Notable changes in positioning include increased exposure to the communication services sector and a lower allocation to materials.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Investors in real estate securities experienced often-fluctuating market conditions throughout the 12 months ending July 31, 2024, initially declining due to concerns about rate hikes but later rallying as hopes for rate cuts in 2024 grew.

•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Fidelity Real Estate Income Composite IndexSM, a 40/25/20/15 blend of the ICE BofA® US Real Estate Index, the MSCI REIT Preferred Index, the FTSE® NAREIT® All REITs Index and the Bloomberg U.S. CMBS ex-AAA Index. Selection among preferred stocks and collateralized mortgage obligations stood out as helping relative performance. Asset allocation modestly contributed this period, especially among preferred stocks, while a stake in cash of roughly 7%, on average, also helped.

•The largest individual relative contributor was a common stock position in Welltower (+39%), an owner of senior-housing properties.

•In contrast, detractors included the fund's underweight in real estate bonds and security selection among real estate common stocks.

•The largest individual relative detractor was a real estate bond investment of Veritas related to a defaulted loan on apartment buildings in San Francisco. The holding lost all its value and was not held in the portfolio on July 31.

•Notable changes in positioning include increased exposure to investment-grade real estate bonds and reductions in high-yield real estate bonds, cash and preferred stocks.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell 2000 Value Index for the fiscal year, led by the information technology sector, especially technology hardware & equipment firms. Solid picks and an underweight in real estate also boosted relative performance. Investment choices in energy helped as well.

•A stake in XPO gained about 82% and was the top individual relative contributor, though the company was not held at period end. Our position in TechnipFMC gained approximately 61% and was another plus. This period we decreased our exposure to the stock. Another notable relative contributor was Insight Enterprises (+54%), one of our largest holdings. All of these contributors were non-benchmark positions.

•In contrast, the biggest detractor from performance versus the benchmark was stock selection in materials. Subpar picks in health care and utilities also hurt.

•The largest individual relative detractor was an outsized stake in O-I Glass (-52%), a stock that was not held at period end. An overweight in Brookfield Infrastructure (-13%), one of the fund's largest holdings this period, proved detrimental as well. Larger-than-benchmark exposure to Owens & Minor (-15%) also hurt.

•Notable changes in positioning include decreased exposure to the consumer discretionary sector and a higher allocation to real estate stocks.

How has the Fund changed?

The fees associated with this class changed during the reporting year.

The variations in class fees are primarily the result of the following changes:

•Management fee
•Performance adjustment fee

The fund's transfer agent and pricing & bookkeeping fees were changed to a fixed rate effective December 1, 2023, through February 29, 2024, in anticipation of the transition to a new management fee structure. Effective March 1, 2024, the fund's management contract was amended to incorporate administrative services previously covered under separate services agreements (transfer agent and pricing & bookkeeping). The amended contract incorporates a management fee rate that may vary by class (subject to a performance adjustment). The Adviser or an affiliate pays certain expenses of managing and operating the fund out of each class's management fee.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, security selection modestly contributed to the fund's performance versus the Fidelity Real Estate Income Composite IndexSM, a 60/25/15 blend of the ICE BofA® US Real Estate Index, the MSCI REIT Preferred Index and the Bloomberg U.S. CMBS ex-AAA Index.

•Selection among preferred stocks and an overweight in commercial mortgage-backed securities also helped relative performance.

•The largest individual relative contributor was a CMBS position referred to as COMM 2012-CR1 C CSTR 5/45.

•In contrast, security selection in commercial mortgage-backed securities detracted, as did picks among real estate bonds and an overweight in preferreds.

•On June 1, 2024, the commercial mortgage-backed securities (CMBS) component of the fund's supplemental benchmark was updated from the Bloomberg U.S. CMBS ex-AAA Index to the Bloomberg U.S. CMBS ex-AAA ex-Agency Guaranteed Index, which better reflects the strategy's focus within the CMBS universe.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, security selection was the primary detractor from the fund's performance versus the Russell 1000 Value Index for the fiscal year, especially among consumer staples companies. Stock picks and an underweight in industrials, primarily within the capital goods industry, also hampered the fund's result. Subpar investment choices in communication services hurt as well.

•The biggest individual relative detractor was a non-benchmark stake in Parex Resources (-28%). Outsized exposure to Kenvue (-19%) and Comcast (-6%) also proved detrimental to performance. The latter was among the fund's largest holdings.

•In contrast, the biggest contributor to performance versus the benchmark was security selection in consumer discretionary, primarily within the consumer services industry. Favorable picks in health care - health care equipment & services firms in particular - and financials boosted the fund's relative performance as well.

•The top individual relative contributor was an overweight in H&R Block (+77%), one of the fund's largest holdings. A stake in Constellation Energy (+93%) was another plus, though the stock was not held at period end. A larger-than-benchmark position in JPMorgan Chase (+38%) also helped. The stock was one of the fund's largest holdings.

•Notable changes in positioning include higher allocations to the consumer discretionary and information technology sectors.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell 2000® Index for the fiscal year, especially within industrials, where our picks in capital goods helped most. Stock picking in health care, primarily within the pharmaceuticals, biotechnology & life sciences industry, also boosted the fund's relative performance.

•The fund's top individual relative contributor was an overweight in IES Holdings (+169%), from the capital goods industry. The stock was one of the fund's biggest holdings at period end, even though we reduced our stake the past 12 months. A non-benchmark stake in Emcor Group gained 75% and was a second notable relative contributor. This period we decreased our investment in Emcor. An overweight in Fabrinet (+79%) also contributed. The company was among our biggest holdings.

•In contrast, the biggest detractor from the fund's performance versus the benchmark was security selection in communication services. Also hurting our result were picks in information technology, primarily within the software & services industry, and utilities

•Not owning Super Micro Computer, a benchmark component that gained 148%, was the fund's biggest individual relative detractor. Not owning MicroStrategy, a benchmark component that gained roughly 215%, was the second-largest relative detractor. Not owning Carvana, a benchmark component that gained 180%, was another notable relative detractor.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•The fund's non-benchmark stake in Vertiv Holdings (+228%) was the top individual relative contributor. The stock was not held at period end. It also helped to overweight FTAI Aviation (+253%). This period we increased our stake, and FTAI Aviation finished the fiscal year as one of our biggest holdings. Another notable relative contributor was our stake in Rover (+99%), a stock that was not held at period end.

•In contrast, the biggest detractors from relative performance were picks in communication services and an overweight in health care. It also hurt to overweight energy.

•The biggest individual relative detractors were an overweight in agilon health (-64%) and a non-benchmark stake in Allegro MicroSystems (-51%). This period we increased our position in Allegro MicroSystems. Our stake in Abercrombie & Fitch (-20%) also detracted. This was an investment we established this period.

•Notable changes in positioning include increased exposure to the financials sector and a lower allocation to consumer staples.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, security selection was the primary contributor to the fund's performance versus the NASDAQ Composite Index for the fiscal year, especially within the industrials sector, where our picks among capital goods stocks helped the most by far. Investment choices in consumer discretionary and information technology also boosted the fund's relative performance.

•The top individual relative contributor was an underweight in Tesla (-13%). A non-benchmark stake in Taiwan Semiconductor Manufacturing (+69%), one of the fund's largest holdings, was another plus. An out-of-benchmark position in Vertiv Holdings (+209%) also helped.

•In contrast, the biggest detractor from performance versus the benchmark was stock selection among consumer staples firms. Outsized exposure to energy stocks and an underweight in information technology hurt as well.

•The biggest individual relative detractor was an underweight in Broadcom (+82%). This was a position we established this period. Outsized exposure to Lululemon Athletica (-32%) also proved detrimental to performance, as did an overweight in Marvell Technology (+3%). The latter was among our largest holdings.

•Notable changes in positioning include decreased exposure to the energy sector and a higher allocation to health care companies.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, security selection was the primary contributor to the fund's performance versus the benchmark for the fiscal year, led by information technology. Security selection in industrials and health care, primarily within the pharmaceuticals, biotechnology & life sciences industry, also boosted the fund's relative performance.

•The top individual relative contributor by far was an overweight in Nvidia (+149%), the fund's biggest holding. It also helped to underweight Apple (+14%), one of the fund's largest holdings, and to hold a non-benchmark stake in Abercrombie & Fitch (+273%).

•In contrast, the biggest detractors from performance versus the benchmark were picks and an overweight in consumer discretionary, primarily within the consumer durables & apparel industry. Security selection in consumer staples, especially within the consumer staples distribution & retail industry, also hampered the fund's result, as did an underweight in information technology.

•The largest individual relative detractor was an overweight in Lululemon Athletica (-32%). We decreased our investment in Lululemon Athletica but the company was among our largest holdings this period. It also hurt to overweight Marvell Technology (+3%), one of our biggest holdings, and to underweight Broadcom (+82%), a position we established this period.
