Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•U.S. equities gained considerably for the 12 months ending June 30, 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. Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength.
•Against this backdrop, security selection was the primary contributor versus the benchmark, especially within industrials. Stock picking in information technology also helped, as did stock picks and an underweight in consumer discretionary, primarily within the automobiles & components industry. Also helping our relative result was stock selection in health care, primarily within the health care equipment & services industry.
•The top individual relative contributor was Nvidia (+204%), one of the fund's largest holdings. This period we decreased our position in Nvidia. The second-largest relative contributor was an underweight in Apple (+9%). Apple was one of our biggest holdings. This period we increased our investment in Apple. Not owning Tesla, a benchmark component that returned approximately -24%, was another notable relative contributor.
•In contrast, the biggest detractor from performance versus the benchmark was an overweight in industrials. Also hurting our result were stock picks in communication services and financials.
•The largest individual relative detractor was an overweight in MongoDB (-39%). This period we increased our stake in MongoDB. A second notable relative detractor was an underweight in Meta Platforms (+76%). This was an investment we established this period. Not owning Broadcom, a benchmark component that gained approximately 88%, was another notable relative detractor.
•Notable changes in positioning include decreased exposure to energy and a higher allocation to information technology.

Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength.

•Against this backdrop, security selection was the primary contributor versus the Russell® Top 200 Index, especially within financials. Security selection in industrials, primarily within the capital goods industry, also helped. Stock selection in information technology also boosted relative performance. Also lifting the fund's relative result were stock picks and an underweight in consumer discretionary, primarily within the automobiles & components industry.

•The top individual relative contributor was an overweight in General Electric (+83%). General Electric was one of our biggest holdings. Not owning Tesla, a benchmark component that returned approximately -24%, was a second notable relative contributor. An underweight in Apple (+9%) also contributed. Apple was one of the fund's largest holdings.

•In contrast, the biggest detractor from performance versus the benchmark was an underweight in information technology, primarily within the semiconductors & semiconductor equipment industry. An overweight in energy also hampered the fund's result. Also detracting from our result was stock picking in consumer staples. Lastly, the fund's position in cash was a notable detractor.

•The biggest individual relative detractor was an underweight in Nvidia (+192%). Nvidia was among the fund's largest holdings. This period we increased our position in Nvidia. A second notable relative detractor was an overweight in Boeing (-16%). Boeing was one of the fund's biggest holdings. This period we increased our stake in Boeing. An overweight in Exxon Mobil (+11%) also detracted. Exxon Mobil was one of our largest holdings.

•Notable changes in positioning include increased exposure to information technology and a lower allocation to health care.

Factors Affecting Performance [Text Block]

What affected the Fund's performance this period?

•U.S. equities gained considerably for the 12 months ending June 30, 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. Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength.
•Against this backdrop, security selection was the primary contributor versus the benchmark, led by industrials, where our stock picks in capital goods helped most. Stock selection in financials also contributed, as did an underweight in consumer discretionary, primarily within the automobiles & components industry. Also lifting the fund's relative result was stock picking in health care, primarily within the health care equipment & services industry.
•The top individual relative contributor was an overweight in General Electric (+83%), one of the fund's largest holdings. The second-biggest relative contributor was an overweight in Wells Fargo (+43%), which was among our biggest holdings. Not owning Tesla, a benchmark component that returned roughly -24%, was another notable relative contributor.
•In contrast, the biggest detractor from performance versus the benchmark was an underweight in information technology, primarily within the semiconductors & semiconductor equipment industry. Stock selection in communication services also hampered the fund's result, as did an overweight in industrials.
•The largest individual relative detractor was an underweight in Nvidia (+192%), one of the fund's biggest holdings. This period we increased Nvidia. A second notable relative detractor was an overweight in Boeing (-14%), which was among the largest holdings. An overweight in Exxon Mobil (+11%) also detracted. Exxon Mobil was one of the fund's 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?

•U.S. equities gained considerably for the 12 months ending June 30, 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. Amid this favorable backdrop for higher-risk assets, stocks continued their late-2023 momentum, powered by signs of continued U.S. economic strength.
•Against this backdrop, the top contributor to performance versus the benchmark was stock selection in health care, primarily within the pharmaceuticals, biotechnology & life sciences industry. Stock picking in consumer discretionary also boosted relative performance, as did an overweight in information technology, primarily within the semiconductors & semiconductor equipment industry.
•The top individual relative contributor was an overweight in Alphabet (+52%), one of our largest holdings. A second notable relative contributor this period was avoiding Tesla, a benchmark component that returned about -24%. An overweight in Nvidia (+192%) also helped. Nvidia was among our largest holdings.
•In contrast, the biggest detractor from performance versus the benchmark was security selection in financials. An overweight in health care also hampered the fund's result, as did stock selection in energy. Lastly, the fund's position in cash detracted.
•The fund's stake in Fortinet returned -23% and was the largest individual relative detractor. Fortinet was not held at period end. The second-largest relative detractor was an overweight in Apple (+10%). Apple was one of our largest holdings. An overweight in Builders FirstSource (-17%), established this period, also hurt.
•Notable changes in positioning include increased exposure to industrials and a lower allocation to consumer staples.
