Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities gained for the 12 months ending January 31, 2025, driven by strong corporate profits, enthusiasm for generative artificial intelligence to drive transformative change and the Federal Reserve's long-anticipated pivot to cutting interest rates.
•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell 1000 Value Index for the fiscal year, led by the information technology sector. Picks in consumer discretionary and industrials, primarily within the capital goods industry, also boosted the fund's relative performance.
•The top individual relative contributor was an overweight in Allison Transmission (+97%). The stock was one of the fund's biggest holdings. Not owning Intel, a benchmark component that returned approximately -54%, also helped. Another notable relative contributor was our non-benchmark stake in Targa Resources (+136%).
•In contrast, the biggest detractor from performance versus the benchmark was stock selection in communication services. Picks in consumer staples, primarily within the food, beverage & tobacco industry, modestly hurt as well. Lastly, the fund's position in cash was another negative.
•The biggest individual relative detractor was an overweight in Concentrix (-40%). A non-benchmark stake in Capgemini returned roughly -17% and also hurt. An underweight in GE Vernova (+163%) detracted as well. GE Vernova was not held in the fund at period end.
•Notable changes in positioning include decreased exposure to the communication services sector and a higher allocation to consumer discretionary companies.

•U.S. equities gained for the 12 months ending January 31, 2025, driven by strong corporate profits, the potential for generative artificial intelligence to drive transformative change and the Federal Reserve's long-anticipated pivot to cutting interest rates.
•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell Midcap Value Index for the fiscal year, led by real estate, where our stock picks in equity real estate investment trusts helped most. Stock picks in materials also boosted the fund's relative performance. Also helping our relative result were picks and an overweight in utilities.
•The top individual relative contributor was an overweight in Vistra (+319%), followed by an overweight in Constellation Energy (+145%). Another notable relative contributor was our non-benchmark stake in Targa Resources (+134%). This period we decreased our investment in all three stocks.
•In contrast, the biggest detractor from performance versus the benchmark was security selection in consumer discretionary, primarily within the consumer discretionary distribution & retail industry. Also hurting our result was stock picking in financials and energy.
•The largest individual relative detractor was our non-benchmark stake in Weatherford International (-40%). This was a position we established this period. The stock was among our biggest holdings at period end. Other notable relative detractors included a non-benchmark stake in Atkore (-49%) and an underweight in MicroStrategy (+143%). Neither stock was in the portfolio at the end of the period.
•Notable changes in positioning include increased exposure to the consumer staples and information technology sectors.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities gained for the 12 months ending January 31, 2025, driven by strong corporate profits, enthusiasm for generative artificial intelligence to drive transformative change and the Federal Reserve's long-anticipated pivot to cutting interest rates.
•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell 3000 Value Index for the fiscal year, especially within utilities. Security selection in industrials and consumer discretionary also boosted the fund's relative performance.
•The fund's non-benchmark stake in Taiwan Semiconductor Manufacturing gained 87% and was the top individual relative contributor. The second-largest relative contributor was an overweight in GE Aerospace (+94%). The company was among our biggest holdings. Another notable relative contributor was an overweight in Vistra (+309%).
•In contrast, the biggest detractor from performance versus the benchmark was an underweight in financials, primarily within the financial services industry. Stock picks in materials also hampered the fund's result. Also hurting our result was an underweight in industrials. Lastly, the fund's position in cash detracted.
•The biggest individual relative detractor was our non-benchmark stake in Samsung Electronics (-33%). The second-largest relative detractor was an overweight in Merck (-18%). An overweight in Danaher (-7%) also detracted. The stock was among our biggest holdings this period.
•Notable changes in positioning include increased exposure to the consumer discretionary sector and a lower allocation to information technology.

•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell 1000 Value Index for the fiscal year, led by the information technology sector. Picks in consumer discretionary and industrials, primarily within the capital goods industry, also boosted the fund's relative performance.
•The top individual relative contributor was an overweight in Allison Transmission (+97%). The stock was one of the fund's biggest holdings. Not owning Intel, a benchmark component that returned approximately -54%, also helped. Another notable relative contributor was our non-benchmark stake in Targa Resources (+136%).
•In contrast, the biggest detractor from performance versus the benchmark was stock selection in communication services. Picks in consumer staples, primarily within the food, beverage & tobacco industry, modestly hurt as well. Lastly, the fund's position in cash was another negative.
•The biggest individual relative detractor was an overweight in Concentrix (-40%). A non-benchmark stake in Capgemini returned roughly -17% and also hurt. An underweight in GE Vernova (+163%) detracted as well. GE Vernova was not held in the fund at period end.
•Notable changes in positioning include decreased exposure to the communication services sector and a higher allocation to consumer discretionary companies.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities gained for the 12 months ending January 31, 2025, driven by strong corporate profits, the potential for generative artificial intelligence to drive transformative change and the Federal Reserve's long-anticipated pivot to cutting interest rates.
•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell Midcap Value Index for the fiscal year, led by real estate, where our stock picks in equity real estate investment trusts helped most. Stock picks in materials also boosted the fund's relative performance. Also helping our relative result were picks and an overweight in utilities.
•The top individual relative contributor was an overweight in Vistra (+319%), followed by an overweight in Constellation Energy (+145%). Another notable relative contributor was our non-benchmark stake in Targa Resources (+134%). This period we decreased our investment in all three stocks.
•In contrast, the biggest detractor from performance versus the benchmark was security selection in consumer discretionary, primarily within the consumer discretionary distribution & retail industry. Also hurting our result was stock picking in financials and energy.
•The largest individual relative detractor was our non-benchmark stake in Weatherford International (-40%). This was a position we established this period. The stock was among our biggest holdings at period end. Other notable relative detractors included a non-benchmark stake in Atkore (-49%) and an underweight in MicroStrategy (+143%). Neither stock was in the portfolio at the end of the period.
•Notable changes in positioning include increased exposure to the consumer staples and information technology sectors.

Not owning Intel, a benchmark component that returned approximately -54%, also helped. Another notable relative contributor was our non-benchmark stake in Targa Resources (+136%).
•In contrast, the biggest detractor from performance versus the benchmark was stock selection in communication services. Picks in consumer staples, primarily within the food, beverage & tobacco industry, modestly hurt as well. Lastly, the fund's position in cash was another negative.
•The biggest individual relative detractor was an overweight in Concentrix (-40%). A non-benchmark stake in Capgemini returned roughly -17% and also hurt. An underweight in GE Vernova (+163%) detracted as well. GE Vernova was not held in the fund at period end.
•Notable changes in positioning include decreased exposure to the communication services sector and a higher allocation to consumer discretionary companies.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities gained for the 12 months ending January 31, 2025, driven by strong corporate profits, enthusiasm for generative artificial intelligence to drive transformative change and the Federal Reserve's long-anticipated pivot to cutting interest rates.
•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell 1000® Value Index for the fiscal year, especially within information technology. Stock selection in consumer discretionary and industrials also boosted the fund's relative performance.
•The top individual relative contributor was an overweight in Allison Transmission (+97%). The stock was one of the fund's biggest holdings. The second-largest relative contributor this period was avoiding Intel, a benchmark component that returned about -54%. Another notable relative contributor was our non-benchmark stake in Targa Resources (+136%). We reduced our position in Targa this period.
•In contrast, the biggest detractor from performance versus the benchmark was security selection in communication services. Also hurting our result were stock picks in consumer staples, primarily within the food, beverage & tobacco industry. Lastly, the fund's position in cash detracted in a rising market.
•The biggest individual relative detractor was an overweight in Concentrix (-40%). A non-benchmark stake in Capgemini returned about -17% and was a second notable relative detractor. Another notable relative detractor was an underweight in GE Vernova (+163%). GE Vernova was not held in the fund at period end.
•Notable changes in positioning include increased exposure to the consumer discretionary sector and a lower allocation to communication services.

•U.S. equities gained for the 12 months ending January 31, 2025, driven by strong corporate profits, the potential for generative artificial intelligence to drive transformative change and the Federal Reserve's long-anticipated pivot to cutting interest rates.
•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell Midcap Value Index for the fiscal year, led by real estate, where our stock picks in equity real estate investment trusts helped most. Stock picks in materials also boosted the fund's relative performance. Also helping our relative result were picks and an overweight in utilities.
•The top individual relative contributor was an overweight in Vistra (+319%), followed by an overweight in Constellation Energy (+145%). Another notable relative contributor was our non-benchmark stake in Targa Resources (+134%). This period we decreased our investment in all three stocks.
•In contrast, the biggest detractor from performance versus the benchmark was security selection in consumer discretionary, primarily within the consumer discretionary distribution & retail industry. Also hurting our result was stock picking in financials and energy.
•The largest individual relative detractor was our non-benchmark stake in Weatherford International (-40%). This was a position we established this period. The stock was among our biggest holdings at period end. Other notable relative detractors included a non-benchmark stake in Atkore (-49%) and an underweight in MicroStrategy (+143%). Neither stock was in the portfolio at the end of the period.
•Notable changes in positioning include increased exposure to the consumer staples and information technology sectors.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities gained for the 12 months ending January 31, 2025, driven by strong corporate profits, the potential for generative artificial intelligence to drive transformative change and the Federal Reserve's long-anticipated pivot to cutting interest rates.
•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell Midcap Value Index for the fiscal year, led by real estate, where our stock picks in equity real estate investment trusts helped most. Stock picks in materials also boosted the fund's relative performance. Also helping our relative result were picks and an overweight in utilities.
•The top individual relative contributor was an overweight in Vistra (+319%), followed by an overweight in Constellation Energy (+145%). Another notable relative contributor was our non-benchmark stake in Targa Resources (+134%). This period we decreased our investment in all three stocks.
•In contrast, the biggest detractor from performance versus the benchmark was security selection in consumer discretionary, primarily within the consumer discretionary distribution & retail industry. Also hurting our result was stock picking in financials and energy.
•The largest individual relative detractor was our non-benchmark stake in Weatherford International (-40%). This was a position we established this period. The stock was among our biggest holdings at period end. Other notable relative detractors included a non-benchmark stake in Atkore (-49%) and an underweight in MicroStrategy (+143%). Neither stock was in the portfolio at the end of the period.
•Notable changes in positioning include increased exposure to the consumer staples and information technology sectors.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities gained for the 12 months ending January 31, 2025, driven by strong corporate profits, enthusiasm for generative artificial intelligence to drive transformative change and the Federal Reserve's long-anticipated pivot to cutting interest rates.
•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell 1000 Value Index for the fiscal year, led by the information technology sector. Picks in consumer discretionary and industrials, primarily within the capital goods industry, also boosted the fund's relative performance.
•The top individual relative contributor was an overweight in Allison Transmission (+97%). The stock was one of the fund's biggest holdings. Not owning Intel, a benchmark component that returned approximately -54%, also helped. Another notable relative contributor was our non-benchmark stake in Targa Resources (+136%).
•In contrast, the biggest detractor from performance versus the benchmark was stock selection in communication services. Picks in consumer staples, primarily within the food, beverage & tobacco industry, modestly hurt as well. Lastly, the fund's position in cash was another negative.
•The biggest individual relative detractor was an overweight in Concentrix (-40%). A non-benchmark stake in Capgemini returned roughly -17% and also hurt. An underweight in GE Vernova (+163%) detracted as well. GE Vernova was not held in the fund at period end.
•Notable changes in positioning include decreased exposure to the communication services sector and a higher allocation to consumer discretionary companies.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities gained for the 12 months ending January 31, 2025, driven by strong corporate profits, the potential for generative artificial intelligence to drive transformative change and the Federal Reserve's long-anticipated pivot to cutting interest rates.
•Against this backdrop, security selection was the primary contributor to the fund's performance versus the Russell Midcap Value Index for the fiscal year, especially within real estate, where our picks in equity real estate investment trusts helped most. Picks in materials also boosted relative performance. Also bolstering our relative result were stock picks and an overweight in utilities.
•The top individual relative contributor was an overweight in Vistra (+315%), followed by an overweight in Constellation Energy (+143%). Another notable relative contributor was our non-benchmark stake in Targa Resources (+134%). This period we decreased our investment in all three stocks.
•In contrast, the biggest detractor from performance versus the benchmark was stock picking in energy. Picks in consumer discretionary, primarily within the consumer discretionary distribution & retail industry, also hampered the fund's result. Also hurting our result were stock picks and an underweight in financials, primarily within the financial services industry.
•The biggest individual relative detractor was our non-benchmark stake in Weatherford International (-39%). This was a position we established this period. The company was one of our biggest holdings at period end. A non-benchmark stake in Atkore returned approximately -49% and was a second notable relative detractor. The stock was not in the portfolio at the end of the period. Another relative detractor was an overweight in ON Semiconductor (-27%). The company was the fund's second-biggest holding at period end. 
•Notable changes in positioning include higher allocations to the consumer staples and information technology sectors.

•U.S. equities gained for the 12 months ending January 31, 2025, driven by strong corporate profits, enthusiasm for generative artificial intelligence to drive transformative change and the Federal Reserve's long-anticipated pivot to cutting interest rates.
•Against this backdrop, security selection contributed to the fund's performance versus the Russell 1000 Index for the fiscal year, especially within industrials, where our stock picks in capital goods helped most. Picks in health care, primarily within the health care equipment & services industry, and communication services also boosted the fund's relative result.
•The top individual relative contributor was an overweight in Broadcom (+89%). This period we meaningfully increased our position in Broadcom, which was one of the largest holdings. Not owning Intel, a benchmark component that returned roughly -54%, was a second notable relative contributor. It also helped to overweight Boston Scientific (+61%). The company was among the top holdings this period.
•In contrast, the biggest detractor from performance versus the benchmark was stock picking in the software & services industry within the information technology sector. Security selection in energy and materials also hurt for the year, as did the fund's position in cash.
•The biggest individual relative detractor was a stake in MongoDB (-40%). The stock was not held at period end. The second-largest relative detractor was an overweight in Advanced Micro Devices (-29%). Not owning Palantir Technologies, a benchmark component that gained about 413%, was another notable relative detractor.
•Notable changes in positioning include a lower allocation to health care stocks.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
•U.S. equities gained for the 12 months ending January 31, 2025, driven by strong corporate profits, enthusiasm for generative artificial intelligence to drive transformative change and the Federal Reserve's long-anticipated pivot to cutting interest rates.
•Against this backdrop, security selection was the primary detractor from the fund's performance versus the Russell 3000 Value Index for the fiscal year, especially within consumer staples, where our picks among food, beverage & tobacco firms hurt most. Also weighing on our relative result was stock selection in utilities and information technology, primarily within the software & services industry.
•The largest individual relative detractor was an overweight in Comcast (-25%). The stock was one of our largest holdings this period. An outsized stake in Centene (-15%), one of the fund's biggest holdings on January 31, hurt as well. Another notable relative detractor this period was avoiding Walmart, a benchmark component that gained roughly 80%.
•In contrast, the biggest contributors to performance versus the benchmark were picks and an underweight in consumer discretionary, primarily within the consumer durables & apparel industry. An overweight in financials, especially banks, and an underweight in real estate, particularly among real estate investment trusts, further boosted the fund's relative performance.
•Not owning Intel, a benchmark component that returned about -54%, was the top individual relative contributor. A stake in Constellation Energy (+53%) also helped, though the stock was not held at period end. An overweight in JPMorgan Chase (+57%) was another plus. The stock was the fund's largest holding at period end.
•Notable changes in positioning include increased exposure to the consumer discretionary sector and a lower allocation to utilities.
