Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities achieved a strong gain in 2025, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and the Federal Reserve's first interest-rate reductions since December 2024.
•Against this backdrop, security selection was the primary detractor from the fund's performance versus the MSCI U.S. IMI Utilities 25/50 Index for the fiscal year, especially within electric utilities. Picks and an overweight in independent power producers & energy traders also hampered the fund's result. Also hurting our result were picks in environmental & facilities services. Lastly, the fund's position in cash detracted.
•The biggest individual relative detractor was an overweight in PG&E (-19%). A second notable relative detractor was untimely positioning in NRG Energy; out holdings gained 23% whereas the stock advanced 79% in the index. NRG was among the fund's largest holdings at period end. Our stake in AES (+1%) also detracted. This period we decreased our stake in AES.
•In contrast, the primary contributor to performance versus the sector index was security selection in heavy electrical equipment. Stock picks in coal & consumable fuels also boosted the fund's relative performance. Also helping our relative result were stock selection and an underweight in multi-utilities.
•The top individual relative contributor was our non-index stake in GE Vernova (+90%). We trimmed the position this period. An out-of-index stake in Cameco gained 85% and was the fund's second-largest relative contributor. This was an investment we established this period. Another notable relative contributor was our non-index stake in First Solar (+32%). This period we increased our position in First Solar. 
•Notable changes in positioning include a lower allocation to multi-utilities.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities achieved a strong gain in 2025, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and, starting in September, the Federal Reserve's first interest-rate reductions since December 2024.
•Against this backdrop, market selection was the primary contributor to the fund's performance versus the MSCI US IMI Information Technology 25/50 Index for the fiscal year, led by an overweight in semiconductors. Picks in technology hardware, storage & peripherals also boosted the fund's relative performance. Also contributing to our result was an underweight in application software.
•The top individual relative contributor was an overweight in Micron Technology (+241%). The stock was one of our biggest holdings at period end. The second-largest relative contributor was an overweight in Western Digital (+284%). An overweight in NVIDIA (+39%) also helped. The company was the fund's largest holding.
•In contrast, the primary detractor from performance versus the industry index was security selection in semiconductors. Picks and an underweight in semiconductor materials & equipment also hampered the fund's result. Also detracting from our result was an underweight in electronic components.
•The biggest individual relative detractor was an overweight in Marvell Technology (-22%). The stock was among our largest holdings. A second notable relative detractor was an overweight in ON Semiconductor (-14%). The stock was among the fund's biggest holdings. An underweight in Broadcom (+51%) also detracted. This period we increased our position in Broadcom.
•Notable changes in positioning include increased exposure to the internet services & infrastructure industry and a lower allocation to technology hardware, storage & peripherals.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities achieved a strong gain in 2025, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and the Federal Reserve's first interest-rate reductions since December 2024.
•Against this backdrop, security selection was the primary detractor from the fund's performance versus the MSCI US IMI Real Estate 25/50 Linked Index for the fiscal year, led by retail. An underweight in health care also hampered the fund's result. Also detracting from our result was stock picking in office.
•The biggest individual relative detractor was an overweight in American Tower (-1%). The stock was the fund's largest holding. A second notable relative detractor was an underweight in CBRE (+22%). The stock was not held at period end. An underweight in Welltower (+50%) also hurt. The company was among the fund's biggest holdings.
•In contrast, the primary contributor to performance versus the real estate index was stock picking in health care. Stock picks and an overweight in real estate services also boosted relative performance. Also contributing to our result was an underweight in office.
•The top individual relative contributor was an overweight in Jones Lang LaSalle (+54%). This was a stake we established this period. The company was among the fund's largest holdings. The second-largest relative contributor was an overweight in Ventas (+35%). The stock was among the fund's largest holdings. Another notable relative contributor was an underweight in Crown Castle (+3%). The stock was not held at period end.
•Notable changes in positioning include decreased exposure to the self storage industry and a higher allocation to health care.

•U.S. equities achieved a strong gain in 2025, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and, starting in September, the Federal Reserve's first interest-rate reductions since December 2024.
•Against this backdrop, market selection was the primary contributor to the fund's performance versus the MSCI US IMI Industrials 25/50 Linked Index for the fiscal year, led by an overweight in heavy electrical equipment. An underweight in human resource & employment services also boosted relative performance. Also bolstering our relative result were picks and an overweight in aerospace & defense.
•The top individual relative contributor was an overweight in GE Vernova (+99%). The stock was among the fund's largest holdings. A second notable relative contributor was an overweight in Howmet Aerospace (+85%). The company was among the fund's biggest holdings. An overweight in GE Aerospace (+85%) also helped. The stock was the fund's biggest holding.
•In contrast, the biggest detractor from performance versus the sector index was stock picking in electrical components & equipment. Stock selection in trading companies & distributors also hampered the fund's result. Also detracting from our result was an overweight in cargo ground transportation.
•The biggest individual relative detractor was an overweight in Ingersoll Rand (-13%). The company was one of our biggest holdings. The second-largest relative detractor was an underweight in RTX (+61%). This was a position we established this period. Another notable relative detractor was an underweight in Caterpillar (+60%).
•Notable changes in positioning include increased exposure to the construction machinery & heavy transportation equipment industry and a lower allocation to electrical components & equipment.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities achieved a strong gain in 2025, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and, starting in September, the Federal Reserve's first interest-rate reductions since December 2024.
•Against this backdrop, market selection was the primary contributor to the fund's performance versus the MSCI US IMI Industrials 25/50 Linked Index for the fiscal year, led by an overweight in heavy electrical equipment. An underweight in human resource & employment services also boosted relative performance. Also bolstering our relative result were picks and an overweight in aerospace & defense.
•The top individual relative contributor was an overweight in GE Vernova (+99%). The stock was among the fund's largest holdings. A second notable relative contributor was an overweight in Howmet Aerospace (+85%). The company was among the fund's biggest holdings. An overweight in GE Aerospace (+85%) also helped. The stock was the fund's biggest holding.
•In contrast, the biggest detractor from performance versus the sector index was stock picking in electrical components & equipment. Stock selection in trading companies & distributors also hampered the fund's result. Also detracting from our result was an overweight in cargo ground transportation.
•The biggest individual relative detractor was an overweight in Ingersoll Rand (-13%). The company was one of our biggest holdings. The second-largest relative detractor was an underweight in RTX (+61%). This was a position we established this period. Another notable relative detractor was an underweight in Caterpillar (+60%).
•Notable changes in positioning include increased exposure to the construction machinery & heavy transportation equipment industry and a lower allocation to electrical components & equipment.

A second notable relative detractor was our stake in UnitedHealth Group (-34%). This period we decreased our position in UnitedHealth. The stock was one of the fund's biggest holdings this period. An underweight in Eli Lilly (+40%) also hurt. The company was the fund's largest holding at period end.
•In contrast, the biggest contributors to performance versus the sector index were stock selection and an overweight in biotechnology. Stock picks in pharmaceuticals also boosted the fund's relative performance. Also contributing to our result were stock selection and an overweight in health care services.
•The top individual relative contributor was our stake in Exact Sciences (+79%). The stock was not held at period end. The second-largest relative contributor was an overweight in Cogent Biosciences (+358%). Another notable relative contributor was an overweight in Alnylam Pharmaceuticals (+69%). The company was one of the fund's largest holdings.
•Notable changes in positioning include decreased exposure to the managed health care industry and a higher allocation to pharmaceuticals.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities achieved a strong gain in 2025, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and, starting in September, the Federal Reserve's first interest-rate reductions since December 2024.
•Against this backdrop, security selection was the primary contributor to the fund's performance versus the MSCI US IMI Financials 5% Capped Linked Index for the year, led by asset management & custody banks. Stock picking among regional banks also boosted the fund's relative result. Investment choices and an underweight in the property & casualty insurance industry helped as well.
•The top individual relative contributor was an overweight in Wells Fargo (+36%), one of our largest holdings. Outsized exposure to Citigroup (+70%) also helped. The company was among our biggest positions this period. Another notable relative contributor was an overweight in FirstCash Holdings (+56%).
•In contrast, the primary detractor from performance versus the sector index was security selection in the investment banking & brokerage group. An overweight in diversified financial services also hampered the fund's result, as did stock picks among research & consulting services firms.
•Not owning Goldman Sachs, an index component that gained about 57%, was the largest individual relative detractor. Avoiding JPMorgan Chase, an index component that gained approximately 37%, hurt as well. An overweight in Reinsurance Group of America (-3%) was another negative. The stock was among the fund's largest holdings.
•Notable changes in positioning include increased exposure to the financial exchanges & data industry and a lower allocation to consumer finance stocks.

•U.S. equities achieved a strong gain in 2025, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and the Federal Reserve's first interest-rate reductions since December 2024.
•Against this backdrop, security selection was the primary contributor to the fund's performance versus the MSCI U.S. IMI Energy 25/50 Index for the fiscal year, led by oil & gas equipment & services. Stock picking in independent power producers & energy traders, and out-of-index group, also boosted the fund's relative performance. Also bolstering our relative result was positioning in the oil & gas exploration & production segment.
•The fund's non-index stake in National Energy Services Reunited gained 75% and was the top individual relative contributor. Not owning ONEOK, an index component that returned -23%, was the second-largest relative contributor. An overweight in TechnipFMC (+55%) also contributed. The stock was among the fund's biggest holdings at period end, though we reduced our stake.
•In contrast, the biggest detractor from performance versus the sector index was security selection in oil & gas storage & transportation. Also hurting our result were underweights in oil & gas drilling and coal & consumable fuels.
•The largest individual relative detractor was our non-index stake in Energy Transfer (-9%). The company was one of the fund's largest holdings. The second-largest relative detractor was an underweight in Williams (+15%). This was a stake we established this period. An overweight in Occidental Petroleum (-15%) also hurt.
•Notable changes in positioning include increased exposure to the oil & gas equipment & services and oil & gas refining & marketing industries.

•Against this backdrop, market selection was the primary detractor from the fund's performance versus the MSCI US IMI Consumer Staples 25/50 Index for the fiscal year, especially an overweight in distillers & vintners. Stock picking in soft drinks & non-alcoholic beverages also hampered the fund's result. Also detracting from our result was an underweight in tobacco.
•The biggest individual relative detractor was an overweight in Energizer Holdings (-40%). The company was one of the fund's largest holdings. The second-largest relative detractor was an overweight in Constellation Brands (-36%). The company was one of our largest holdings this period. Another notable relative detractor was an overweight in Boston Beer (-35%).
•In contrast, the biggest contributor to performance versus the sector index was stock picking in personal care products. An overweight in soft drinks & non-alcoholic beverages also boosted the fund's relative performance. Also helping our relative result were picks in tobacco.
•The fund's non-index stake in British American Tobacco gained about 65% and was the top individual relative contributor. A second notable relative contributor was an overweight in Bunge Global (+18%). Another notable relative contributor was an overweight in Estee Lauder (+41%). This period we decreased our position in Estee Lauder. The stock was among our biggest holdings this period.
•Notable changes in positioning include increased exposure to the food retail and tobacco industries.

•In contrast, the biggest contributor to performance versus the sector index was stock picking in personal care products. An overweight in soft drinks & non-alcoholic beverages also boosted the fund's relative performance. Also helping our relative result were picks in tobacco.
•The fund's non-index stake in British American Tobacco gained about 65% and was the top individual relative contributor. A second notable relative contributor was an overweight in Bunge Global (+18%). Another notable relative contributor was an overweight in Estee Lauder (+41%). This period we decreased our position in Estee Lauder. The stock was among our biggest holdings this period.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities achieved a strong gain in 2025, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and the Federal Reserve's first interest-rate reductions since December 2024.
•Against this backdrop, market selection was the primary detractor from the fund's performance versus the MSCI US IMI Consumer Staples 25/50 Index for the fiscal year, especially an overweight in distillers & vintners. Stock picking in soft drinks & non-alcoholic beverages also hampered the fund's result. Also detracting from our result was an underweight in tobacco.
•The biggest individual relative detractor was an overweight in Energizer Holdings (-40%). The company was one of the fund's largest holdings. The second-largest relative detractor was an overweight in Constellation Brands (-36%). The company was one of our largest holdings this period.

•Against this backdrop, security selection and industry positioning contributed to the fund's performance versus the MSCI US IMI Consumer Discretionary 25/50 Index for the year, led by choices in apparel, accessories & luxury goods.

•U.S. equities achieved a strong gain in 2025, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and the Federal Reserve's first interest-rate reductions since December 2024.
•Against this backdrop, security selection was the primary contributor to the fund's performance versus the MSCI U.S. IMI Communication Services 25/50 Index for the fiscal year, led by movies & entertainment.

•The top individual relative contributor was our underweight stake in T-Mobile US (-14%). This was an investment we established this period. The company was one of our biggest holdings at period end. The second-largest relative contributor was an underweight in Comcast (-17%). The stock was not held at period end. Our lighter-than-index stake in AT&T (+8%) also contributed. The stock was among our biggest holdings.
•In contrast, the primary detractor from performance versus the sector index was an overweight in movies & entertainment. Also hurting our result were stock picks in broadline retail and integrated telecommunication services.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities achieved a strong gain in 2025, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and, starting in September, the Federal Reserve's first interest-rate reductions since December 2024.
•Against this backdrop, market selection was the primary contributor to the fund's performance versus the MSCI US IMI Industrials 25/50 Linked Index for the fiscal year, led by an overweight in heavy electrical equipment. An underweight in human resource & employment services also boosted relative performance. Also bolstering our relative result were picks and an overweight in aerospace & defense.
•The top individual relative contributor was an overweight in GE Vernova (+99%). The stock was among the fund's largest holdings. A second notable relative contributor was an overweight in Howmet Aerospace (+85%). The company was among the fund's biggest holdings. An overweight in GE Aerospace (+85%) also helped. The stock was the fund's biggest holding.
•In contrast, the biggest detractor from performance versus the sector index was stock picking in electrical components & equipment. Stock selection in trading companies & distributors also hampered the fund's result. Also detracting from our result was an overweight in cargo ground transportation.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities achieved a strong gain in 2025, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and the Federal Reserve's first interest-rate reductions since December 2024.
•Against this backdrop, security selection was the primary detractor from the fund's performance versus the MSCI US IMI Materials 25/50 Linked Index for the fiscal year, especially within diversified metals & mining. Picks in gold also hampered the fund's result. Also hurting our result was an overweight in fertilizers & agricultural chemicals.
•The largest individual relative detractor was an underweight in Newmont (+173%). This was a stake we established this period. The company was among our biggest holdings at period end. The second-largest relative detractor was an overweight in Mosaic (+2%). This was an investment we established this period. The company was among our biggest holdings. Another notable relative detractor was an underweight in Freeport-McMoRan (+35%).
•In contrast, the largest contributor to performance versus the sector index was an overweight in diversified metals & mining. Security selection and an overweight in copper also boosted the fund's relative performance. Also contributing to our result was an underweight in paper & plastic packaging products & materials.
•The fund's stake in First Quantum Minerals gained 107% and was the top individual relative contributor. The company was one of our largest holdings. A second notable relative contributor was our stake in Wheaton Precious Metals (+111%). This period we decreased our investment in Wheaton Precious Metals.

•U.S. equities achieved a strong gain in 2025, extending a historically fast rebound that began in early April, bolstered by strong corporate fundamentals, a resilient economy and the Federal Reserve's first interest-rate reductions since December 2024.
•Against this backdrop, security selection was the primary detractor from the fund's performance versus the MSCI U.S. IMI Utilities 25/50 Index for the fiscal year, especially within electric utilities. Picks and an overweight in independent power producers & energy traders also hampered the fund's result. Also hurting our result were picks in environmental & facilities services. Lastly, the fund's position in cash detracted.
•The biggest individual relative detractor was an overweight in PG&E (-19%). A second notable relative detractor was untimely positioning in NRG Energy; out holdings gained 23% whereas the stock advanced 79% in the index. NRG was among the fund's largest holdings at period end. Our stake in AES (+1%) also detracted. This period we decreased our stake in AES.
•In contrast, the primary contributor to performance versus the sector index was security selection in heavy electrical equipment. Stock picks in coal & consumable fuels also boosted the fund's relative performance. Also helping our relative result were stock selection and an underweight in multi-utilities.
•The top individual relative contributor was our non-index stake in GE Vernova (+90%). We trimmed the position this period. An out-of-index stake in Cameco gained 85% and was the fund's second-largest relative contributor. This was an investment we established this period. Another notable relative contributor was our non-index stake in First Solar (+32%). This period we increased our position in First Solar. 
•Notable changes in positioning include a lower allocation to multi-utilities.
