Key contributors to (↑) and detractors from (↓) performance, relative to the Russell 1000 ® ↑ Not owning Index component Chevron Corp. and an underweight position in Index component ExxonMobil Corp. ― both energy exploration and production firms ― helped Index-relative returns as the prices of both stocks performed poorly during a period of volatile and declining demand for oil and natural gas worldwide ↑ An overweight position in NVIDIA Corp., a major microchip supplier for artificial intelligence (AI) applications, helped returns as its stock price tripled ↑ Among sectors, underweight positions in energy and real estate, and an overweight position in information technology contributed to Index-relative returns ↓ Not owning Index component and Facebook parent Meta Platforms, Inc. hampered returns as its stock price rose on strong advertising revenue and user growth ↓ An underweight position in aircraft engine maker GE Aerospace hampered returns as increasing demand for air travel helped the firm’s stock price double ↓ An overweight position in energy firm Occidental Petroleum Corp. dropped in value on falling oil and gas prices, and higher debt due to a business acquisition ↓ Among sectors, stock selections and an underweight position in communication services, and stock selections in industrials detracted from relative returns | |

Key contributors to (↑) and detractors from (↓) performance, relative to the Russell 1000 ® ↑ Not owning Index components ExxonMobil Corp. and Chevron Corp. ― both energy exploration and production companies ― contributed to returns relative to the Index as the prices of both stocks performed poorly during a period of volatile and declining demand for oil and natural gas worldwide ↑ Not owning Index component and health care firm Johnson & Johnson helped relative returns as a talcum powder lawsuit weighed on J&J’s stock price ↑ Among sectors, an underweight in energy, stock selections and an overweight in financials, and stock selections and an underweight in real estate helped returns ↓ An underweight position in Micron Technology, Inc. hurt returns as its stock appreciated on AI-driven demand for the firm’s memory and storage semiconductors ↓ An underweight position in aircraft engine maker GE Aerospace hampered returns as increasing demand for air travel helped the firm’s stock price double ↓ An overweight position in semiconductor maker Intel Corp. declined in value on concerns about increasing competition in microchip sales for AI applications ↓ Among sectors, stock selections in the information technology, health care, and industrials sectors detracted from Index-relative returns during the period | |

Dell was sold by period-end ↑ Not owning Index component and medical device company DexCom, Inc. aided returns as lower-than-expected sales of its diabetes products depressed its stock price ↑ Among sectors, underweight positions in energy and real estate, and stock selections and an underweight position in materials helped Index-relative returns | |
