Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
U.S. equities achieved a strong gain for the 12 months ending September 30, 2024, driven by a resilient economy, the promise of generative artificial intelligence and the Federal Reserve's long-anticipated pivot, on September 18, to cutting interest rates. Growth stocks led the way, with the information technology and communication services sectors enabling transformative change and semiconductor-related stocks a particular standout.
Against this backdrop, market selection was the primary detractor from the fund's performance versus the benchmark S&P 500® index for the fiscal year, especially an overweight in energy. An underweight in information technology, primarily within the semiconductors & semiconductor equipment industry, also hampered the fund's result. Also hurting our result was security selection in communication services, primarily within the media & entertainment industry.
The biggest individual relative detractor was an overweight in Exxon Mobil (+3%). The stock was one of the fund's biggest holdings. A second notable relative detractor was an underweight in Nvidia (+179%). This period we increased our investment in Nvidia. The stock was among the fund's largest holdings. Another notable relative detractor was an overweight in Boeing (-21%). The stock was one of our biggest holdings.
In contrast, the biggest contributor to performance versus the benchmark was stock selection in industrials, primarily within the capital goods industry. Stock picking in health care and financials also boosted relative performance, as did an outsized investment in banks.
The top individual relative contributor was an overweight in General Aerospace (+116%). The company was one of the fund's largest holdings. A second notable relative contributor was an overweight in GE Vernova (+83%). This was an investment we established this period. The company was one of the fund's biggest holdings on September 30. Lastly, a non-benchmark stake in Vertiv Holdings gained roughly 168% and helped.
Notable changes in positioning include increased exposure to the information technology sector and a lower allocation to energy.

The top individual relative contributor was our stake in Nvidia (+178%). The company was one of our largest holdings. The second-largest relative contributor was an overweight in Trane Technologies (+94%). The company was among our biggest holdings at period end. Another notable relative contributor was an overweight in Eaton (+57%). This period we decreased our position in Eaton. The company was one of our largest holdings this period. 
In contrast, the biggest detractor from performance versus the benchmark was security selection in financials. Security selection and an overweight in energy also hampered the fund's result. Also detracting from our result was an overweight in materials. Lastly, the fund's position in cash detracted. 
The largest individual relative detractor was an underweight in Broadcom (+111%). This was a position we established this period. The second-largest relative detractor was our stake in Boeing (-17%). The stock was not held at period end. Our stake in Schlumberger (-18%) also detracted. The stock was not held at period end. 
Notable changes in positioning include lower allocations to the energy and communication services sectors.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
U.S. equities achieved a strong gain for the 12 months ending September 30, 2024, driven by a resilient economy, the promise of generative artificial intelligence and the Federal Reserve's long-anticipated pivot, on September 18, to cutting interest rates. Growth stocks led the way, with the information technology and communication services sectors enabling transformative change and semiconductor-related stocks a particular standout.
Against this backdrop, market selection was the primary detractor from the fund's performance versus the benchmark S&P 500® index for the fiscal year, especially an overweight in energy. An underweight in information technology, primarily within the semiconductors & semiconductor equipment industry, also hampered the fund's result. Also hurting our result was security selection in communication services, primarily within the media & entertainment industry.
The biggest individual relative detractor was an overweight in Exxon Mobil (+3%). The stock was one of the fund's biggest holdings. A second notable relative detractor was an underweight in Nvidia (+179%). This period we increased our investment in Nvidia. The stock was among the fund's largest holdings. Another notable relative detractor was an overweight in Boeing (-21%). The stock was one of our biggest holdings.
In contrast, the biggest contributor to performance versus the benchmark was stock selection in industrials, primarily within the capital goods industry. Stock picking in health care and financials also boosted relative performance, as did an outsized investment in banks.
The top individual relative contributor was an overweight in General Aerospace (+116%). The company was one of the fund's largest holdings. A second notable relative contributor was an overweight in GE Vernova (+83%). This was an investment we established this period. The company was one of the fund's biggest holdings on September 30. Lastly, a non-benchmark stake in Vertiv Holdings gained roughly 168% and helped.
Notable changes in positioning include increased exposure to the information technology sector and a lower allocation to energy.

Another notable relative contributor was an overweight in Eaton (+57%). This period we decreased our position in Eaton. The company was one of our largest holdings this period. 
In contrast, the biggest detractor from performance versus the benchmark was security selection in financials. Security selection and an overweight in energy also hampered the fund's result. Also detracting from our result was an overweight in materials. Lastly, the fund's position in cash detracted. 
The largest individual relative detractor was an underweight in Broadcom (+111%). This was a position we established this period. The second-largest relative detractor was our stake in Boeing (-17%). The stock was not held at period end. Our stake in Schlumberger (-18%) also detracted. The stock was not held at period end. 
Notable changes in positioning include lower allocations to the energy and communication services sectors.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
U.S. equities achieved a strong gain for the 12 months ending September 30, 2024, driven by a resilient economy, the promise of generative artificial intelligence and the Federal Reserve's long-anticipated pivot, on September 18, to cutting interest rates. Growth stocks led the way, with the information technology and communication services sectors enabling transformative change and semiconductor-related stocks a particular standout. 
Against this backdrop, security selection was the primary contributor to the fund's performance versus the benchmark S&P 500® index for the fiscal year, led by industrials. Picks in consumer discretionary and health care, primarily within the pharmaceuticals, biotechnology & life sciences industry, also boosted the fund's relative performance. 
The top individual relative contributor was our stake in Nvidia (+178%). The company was one of our largest holdings. The second-largest relative contributor was an overweight in Trane Technologies (+94%). The company was among our biggest holdings at period end. Another notable relative contributor was an overweight in Eaton (+57%). This period we decreased our position in Eaton. The company was one of our largest holdings this period. 
In contrast, the biggest detractor from performance versus the benchmark was security selection in financials. Security selection and an overweight in energy also hampered the fund's result. Also detracting from our result was an overweight in materials. Lastly, the fund's position in cash detracted. 
The largest individual relative detractor was an underweight in Broadcom (+111%). This was a position we established this period. The second-largest relative detractor was our stake in Boeing (-17%). The stock was not held at period end. Our stake in Schlumberger (-18%) also detracted. The stock was not held at period end. 
Notable changes in positioning include lower allocations to the energy and communication services sectors.

U.S. equities achieved a strong gain for the 12 months ending September 30, 2024, driven by a resilient economy, the promise of generative artificial intelligence and the Federal Reserve's long-anticipated pivot, on September 18, to cutting interest rates. Growth stocks led the way, with the information technology and communication services sectors enabling transformative change and semiconductor-related stocks a particular standout.
Against this backdrop, market selection was the primary detractor from the fund's performance versus the benchmark S&P 500® index for the fiscal year, especially an overweight in energy. An underweight in information technology, primarily within the semiconductors & semiconductor equipment industry, also hampered the fund's result. Also hurting our result was security selection in communication services, primarily within the media & entertainment industry.
The biggest individual relative detractor was an overweight in Exxon Mobil (+3%). The stock was one of the fund's biggest holdings. A second notable relative detractor was an underweight in Nvidia (+179%). This period we increased our investment in Nvidia. The stock was among the fund's largest holdings. Another notable relative detractor was an overweight in Boeing (-21%). The stock was one of our biggest holdings.
In contrast, the biggest contributor to performance versus the benchmark was stock selection in industrials, primarily within the capital goods industry. Stock picking in health care and financials also boosted relative performance, as did an outsized investment in banks.
The top individual relative contributor was an overweight in General Aerospace (+116%). The company was one of the fund's largest holdings. A second notable relative contributor was an overweight in GE Vernova (+83%). This was an investment we established this period. The company was one of the fund's biggest holdings on September 30. Lastly, a non-benchmark stake in Vertiv Holdings gained roughly 168% and helped.
Notable changes in positioning include increased exposure to the information technology sector and a lower allocation to energy.

Factors Affecting Performance [Text Block] What affected the Fund's performance this period?
 
U.S. equities achieved a strong gain for the 12 months ending September 30, 2024, driven by a resilient economy, the promise of generative artificial intelligence and the Federal Reserve's long-anticipated pivot, on September 18, to cutting interest rates. Growth stocks led the way, with the information technology and communication services sectors enabling transformative change and semiconductor-related stocks a particular standout.
Against this backdrop, market selection was the primary detractor from the fund's performance versus the benchmark S&P 500® index for the fiscal year, especially an overweight in energy. An underweight in information technology, primarily within the semiconductors & semiconductor equipment industry, also hampered the fund's result. Also hurting our result was security selection in communication services, primarily within the media & entertainment industry.
The biggest individual relative detractor was an overweight in Exxon Mobil (+3%). The stock was one of the fund's biggest holdings. A second notable relative detractor was an underweight in Nvidia (+179%). This period we increased our investment in Nvidia. The stock was among the fund's largest holdings. Another notable relative detractor was an overweight in Boeing (-21%). The stock was one of our biggest holdings.
In contrast, the biggest contributor to performance versus the benchmark was stock selection in industrials, primarily within the capital goods industry. Stock picking in health care and financials also boosted relative performance, as did an outsized investment in banks.
The top individual relative contributor was an overweight in General Aerospace (+116%). The company was one of the fund's largest holdings. A second notable relative contributor was an overweight in GE Vernova (+83%). This was an investment we established this period. The company was one of the fund's biggest holdings on September 30. Lastly, a non-benchmark stake in Vertiv Holdings gained roughly 168% and helped.
Notable changes in positioning include increased exposure to the information technology sector and a lower allocation to energy.
