Factors Affecting Performance [Text Block] | What drove fund performance during the past 12 months? U.S. stocks advanced in 2024, buoyed by generally favorable earnings and strong gains in companies exposed to artificial intelligence (AI). Despite inflation exceeding the Federal Reserve’s 2% target, the central bank began cutting rates in September as the labor market cooled. Stocks rallied after the U.S. elections in November as investors expected that President-elect Donald Trump's policies would benefit corporate profits, though volatility rose over concerns about his tariff and tax plans. Versus the S&P 500 Index, stock selection in information technology led contributors to relative performance. NVIDIA was a significant contributor, as the company thrived as demand increased sharply for its graphics processing units (GPU)—driven particularly by generative AI advancement—alongside positive sentiment for its high-end GPU chip innovation. Stock choices in materials also added value, led by International Paper. In contrast, stock selection in industrials and business services led relative detractors. Despite solid performance against a tough industry backdrop, Old Dominion Freight Line shares fell due to a prolonged freight recession that led to lower freight volumes, decreased fuel charge revenues, and increased operational expenses. In health care, stock choices and an overweight exposure to the sector also hurt, especially our position in Regeneron Pharmaceuticals. The fund is actively managed and aims for long-term capital growth through fundamental, bottom-up research, blending growth and value investing to select stocks with favorable fundamentals, earnings potential, and valuation. Over the year, the fund increased its absolute position in information technology and reduced its absolute allocation to health care. | | |
