Factors Affecting Performance [Text Block]

What drove fund performance during the past 12 months?

  • U.S. equities rose in 2025, with favorable corporate earnings, artificial intelligence tailwinds, and a broadly constructive regulatory environment helping overcome tariff concerns. As the year progressed, the U.S. Federal Reserve resumed short-term interest rate cuts despite continued elevated inflation.

  • The following contributed most to the portfolio’s performance, relative to the S&P 500 Index, during the reporting period: stock selection in financials, led by JPMorgan Chase, which benefited from strong earnings with rising net interest income, and stock selection in industrials and business services, where GE Aerospace and Howmet Aerospace produced impressive earnings and benefited from the post-pandemic aerospace recovery.

  • The following detracted most from portfolio performance, relative to the benchmark, during the reporting period: an underweight in communication services and a combination of our underweight and stock choices in information technology. A handful of names that do not meet our dividend growth criteria and, thus, are not in our investable universe led returns in these sectors.

  • The fund seeks dividend income and long-term capital growth primarily through investments in stocks. The fund will normally invest at least 65% of its total assets in the common stocks of dividend-paying companies that we expect to increase their dividends over time and also provide long-term appreciation. Our in-house research team looks for stocks with sustainable, above-average growth in earnings and dividends, and we attempt to buy them when they are temporarily out of favor or undervalued by the market.
