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, led by picks in the consumer discretionary sector. Stock selection in information technology, primarily within the semiconductors & semiconductor equipment industry, also boosted the fund's relative performance.

•The fund's non-benchmark stake in Nvidia gained approximately 150% and was the top individual relative contributor. The stock was among our largest holdings. An overweight in Williams-Sonoma (+128%) also contributed, as did avoiding Unity Software, a benchmark component that returned about -64%.

•In contrast, the biggest detractor from performance versus the benchmark was stock picking in communication services, utilities and materials.

•Not owning Godaddy, a benchmark component that gained roughly 89%, was the biggest individual relative detractor. Not owning Fair Isaac, a benchmark component that gained 91%, was the second-largest relative detractor. Another notable relative detractor was an overweight in Estee Lauder (-43%).

•Notable changes in positioning include higher allocations to the consumer discretionary and communication services sectors.

•Application of FMR's environmental, social, and governance (ESG) ratings process and/or its sustainable investing exclusion criteria may affect the Fund's exposure to certain issuers, sectors, regions, and countries and may affect the Fund's performance.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, both security selection and sector positioning detracted from the fund's performance versus the Russell 1000 Value Index for the fiscal year, especially in consumer staples. Subpar stock picks in communication services also hampered the fund's result. Investment choices and an underweight in industrials, primarily within the capital goods industry, hurt as well.

•The largest individual relative detractor was an outsized stake in Lamb Weston Holdings (-36%). An overweight in Kenvue (-9%), where we increased our position this period, also was detrimental to performance. Larger-than-benchmark exposure to Comcast (-6%), one of our biggest holdings, was another challenge.

•In contrast, the biggest contributors to performance versus the benchmark were stock picks and an underweight among consumer discretionary firms. Investment choices and outsized exposure to financials - banks in particular - also boosted the fund's relative performance. Comparatively light exposure to the real estate sector, especially the equity real estate investment trusts industry, proved advantageous as well.

•The top individual relative contributor was an overweight in H&R Block (+77%). An outsized stake in Constellation Energy (+90%) was another plus, though the stock was not held at period end. An underweight in ConocoPhillips (-3%) helped as well. The stock was not held at period end.

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

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, industry positioning was the primary detractor from the fund's performance versus the MSCI US IMI Real Estate 25/50 Index for the fiscal year, especially a lack of exposure to regional malls. Stock picks in the infrastructure category also hampered the fund's result, as did investment choices and an overweight in apartments.

•The largest individual relative detractor was an outsized stake in SBA Communications (+2%). This period we decreased our position in the stock, making it one of the fund's largest holdings this period. Avoiding Simon Property Group, an index component that gained roughly 30%, proved detrimental to performance as well. A larger-than-index position in Mid-America Apartment Communities (-3%) also hurt.

•In contrast, the primary contributor to performance versus the real estate index was security selection in health care. Stock picking and an underweight in the diversified segment of the market also boosted the fund's relative performance. Favorable investment choices among freestanding real estate stocks helped as well.

•The top individual relative contributor was our timely positioning in Costar (-7%), followed by an overweight stake in Ventas (+17%). The latter was one of the fund's biggest holdings. Comparatively light exposure to Realty Income (-1%) was another plus.

•Notable changes in positioning include increased exposure to the self storage industry and a lower allocation to lodging resorts.

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 S&P 500® index for the fiscal year, especially within industrials. Stock selection and an underweight in consumer discretionary and picks and an overweight in utilities also boosted the fund's relative performance.
•Not owning Tesla, a benchmark component that returned -13%, was the top individual relative contributor. The second-largest relative contributor was an overweight in Constellation Energy (+97%). This period we increased our position in the stock. Another notable relative contributor was an overweight in Eli Lilly (+78%), which was one of the fund's biggest holdings this period.
•In contrast, stock picking and an underweight in financials notably detracted from the fund's performance versus the benchmark. An overweight in materials also hampered the fund's result, as did our stock picks in consumer staples, primarily within the household & personal products industry.
•The biggest individual relative detractor was an overweight in Boeing (-20%). This period we increased our stake. The second-largest relative detractor was our stake in ON Semiconductor (-29%), a stock that was not held at period end. Another notable relative detractor was our holding in Broadcom (+24%). This was an investment we established this period. The company was one of our biggest holdings at period end.
•Notable changes in positioning include decreased exposure to the materials sector and a higher allocation to financials.

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 consumer discretionary and health care also boosted the fund's relative performance.

•The top individual relative contributor was our stake in Nvidia (+153%). The stock was one of our biggest holdings. The second-largest relative contributor was an overweight in Sprouts Farmers Market (+145%). An underweight in Tesla (-13%) also helped.

•In contrast, security selection in communication services, primarily within the media & entertainment industry, detracted.

•The biggest individual relative detractor was an overweight in ON Semiconductor (-27%). This period we increased our position in ON Semiconductor. The second-largest relative detractor this period was avoiding Broadcom, a benchmark component that gained 82%.

•Notable changes in positioning include decreased exposure to the consumer staples sector and a higher allocation to communication services.

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, information technology - the ETF's largest sector weighting - gained 31% and contributed most to the fund's performance for the fiscal year. Health care, which gained 27%, also helped, benefiting from the pharmaceuticals, biotechnology & life sciences industry (+29%), as did consumer discretionary, which advanced 45%. The financials sector rose approximately 27%, while utilities gained about 38% and energy advanced 21%. Other contributors included the consumer staples (+12%), industrials (+35%), real estate (+20%), communication services (+30%) and materials (+1%) sectors.
•Turning to individual stocks, the top contributor was Nvidia (+171%), from the semiconductors & semiconductor equipment group. From the same category, Broadcom gained roughly 97%. Vistra (+75%), from the utilities sector, also contributed. In pharmaceuticals, biotechnology & life sciences, Eli Lilly (+79%) helped, as did Microsoft (+26%), from the software & services industry.
•Conversely, the biggest detractor was Alpha Metallurgical Resources (-21%), from the materials sector. Pfizer (-21%) and Bristol-Myers Squibb (-18%), within the pharmaceuticals, biotechnology & life sciences category, also hindered the fund. Molina Healthcare (-15%), from the health care equipment & services industry, further hurt the fund, as did BellRing Brands, in household & personal products.

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, led by the information technology sector. Picks among industrials stocks, primarily within the capital goods industry, also helped. Investment choices in health care further boosted the fund's relative performance.

•The top individual relative contributor was an overweight in Nvidia (+151%). The company was one of our largest holdings. Not owning Tesla, a benchmark component that returned -13%, was another plus. Outsized exposure to Eli Lilly (+79%) also helped. The stock was one of the fund's biggest holdings.

•In contrast, the biggest detractor from performance versus the benchmark was a sizable overweight in industrials. Larger-than-benchmark exposure to materials and consumer discretionary also hurt, especially within the consumer services industry.

•The largest individual relative detractor was an overweight in ON Semiconductor (-28%), though the stock was not held at period end. Untimely positioning in Zoetis (-17%) and Uber Technologies (-20%) also proved detrimental to performance.

•Notable changes in positioning include increased exposure to the communication services and consumer discretionary sectors.

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 2500 Index for the fiscal year, especially within the industrials sector, capital goods firms in particular. Stock picking in consumer discretionary and energy also boosted the fund's relative performance.

•The top individual relative contributor was an overweight in TechnipFMC (+63%), the fund's largest position. Outsized exposure to Vertiv Holdings (+205%) and EMCOR Groups (+75%) helped as well. This period we increased our stake in the latter, making it one of the portfolio's biggest holdings.

•In contrast, the biggest detractors from performance versus the benchmark were subpar picks and an underweight in utilities. Investment choices in materials and information technology, primarily within the software & services industry, also hurt.

•On a stock-specific basis, a non-benchmark stake in ON Semiconductor (-27%) was the biggest relative detractor. An overweight in O-I Glass (-48%), where we decreased our position this period, also was detrimental to performance. A comparatively large holding in Chemours (-32%) was another negative.

•Notable changes in positioning include a lower allocation to information technology 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 benchmark for the fiscal year, led by information technology. Security selection and an underweight in industrials and picks and an overweight in communication services, primarily within the media & entertainment industry, also boosted the fund's relative performance.

•The top individual relative contributor by far was an overweight in Nvidia (+151%), the fund's biggest holding. A non-benchmark stake in Abercrombie & Fitch (+268%) and an overweight in Amazon.com (+40%), two positions we increased this period, also helped. Amazon.com was among the fund's biggest holdings.

•In contrast, the biggest detractor from relative performance was 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 fund's position in cash also weighed on relative performance.

•The biggest individual relative detractor was an underweight in Broadcom (+82%), a position we established this period. A non-benchmark stake in ON Semiconductor (-28%) and an overweight in Marvell Technology (+3%) also detracted. This period we increased our investment in ON Semiconductor and Marvell was one of our biggest holdings.

•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, market selection was the primary contributor to the fund's performance versus the Russell 1000 Growth Index for the fiscal year, helped by an underweight in consumer discretionary, where an underweight in automobiles & components helped most. Stock selection in industrials and information technology also boosted the fund's relative performance.
•The top individual relative contributor was a sizable underweight in Apple (+14%). This period we increased our stake in Apple, and the stock was among the fund's biggest holdings at period end. The second-largest relative contributor was an overweight in Nvidia (+151%), which was the fund's largest holding as of July 31. Another notable relative contributor was an underweight in Tesla (-13%). The stock was not held at the end of the period.
•In contrast, the biggest detractor from performance versus the benchmark was stock picking in communication services, primarily within the media & entertainment industry. Stock picks in financials also hampered the fund's result.
•The largest individual relative detractor was an overweight in Roku (-38%). This period we decreased our position. A non-benchmark stake in ON Semiconductor returned -28%. An underweight in Broadcom (+82%) also hurt. This was an investment we established this period.
•Notable changes in positioning include increased exposure to the consumer discretionary and industrials sectors.

What affected the Fund's performance this period?

•Against this backdrop, information technology gained about 29% and contributed most to the fund's performance for the fiscal year.

The portfolio's stakes in consumer staples (+25%), utilities (+31%), energy (+14%), real estate (+14%) and materials (+8%) companies were advantageous as well.

•Turning to individual stocks, the top contributor was Nvidia (+148%), within the semiconductors & semiconductor equipment industry.

•In contrast, the biggest detractor was Tesla (-24%), within the automobiles & components industry.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•Against this backdrop, the information technology sector gained 45% and contributed most to the fund's performance for the fiscal year. Exposure to industrials stocks also helped (+20%). Stakes among financials (+27%), utilities (+23%) and energy (+10%) companies were advantageous as well. Holdings in the consumer staples (+4%), health care (+9%), real estate (+4%) and communication services (+12%) sectors further aided the portfolio's result. The fund's international holdings contributed overall, despite a broadly stronger U.S. dollar.

•Turning to individual holdings, the biggest contributor was Nvidia (+155%), a company in the semiconductors & semiconductor equipment industry. In the same industry, a position in Broadcom (+83%) was another plus. Software & services firm Microsoft rose approximately 26% and boosted the fund as well. Apple, within the technology hardware & equipment group, was up 14% and provided an added performance lift. Also helping was transportation company Kawasaki Kisen Kaisha (+59%).

•In contrast, consumer discretionary stocks were effectively flat (0%), detracting the most from performance. This group was notably pressured by the consumer durables & apparel (-30%) industry.

•On a stock-specific basis, the biggest detractor was Walgreens Boots Alliance (-45%), a consumer staples distribution & retail firm. Exposure to United Parcel Service, within the transportation industry, returned about -27% and hurt as well. Stakes in equity real estate investment trusts Medical Properties Trust (-63%) and Healthcare Realty Trust (-27%) also were detrimental to performance. Lastly, 3M (-14%), within the capital goods industry, was another negative.

•Conversely, the fund's positions in the consumer discretionary sector returned -2% and hurt most, notably pressured by the consumer services industry (-12%). The portfolio's international holdings detracted overall, hampered in part by broadly stronger U.S. dollar.

•On a stock-specific basis, the biggest detractor was consumer durables & apparel company Nike (-31%). In transportation, a stake in United Parcel Service (-27%) was another challenge for the fund. Pharmaceuticals, biotechnology & life sciences firm Bristol-Myers Squibb returned approximately -20% and hurt as well.
