What factors influenced results
U.S. equity markets delivered strong returns, rebounding from early 2025 volatility on the back of a late-stage rally in the technology sector. During the fund’s fiscal period, small and mid-cap equities generated modest returns and lagged large-cap stocks. Overall, the U.S. economy maintained steady growth, despite a contraction in the first quarter of 2025 amid rising uncertainty over the implementation of proposed tariffs. As inflation moderated, the U.S. Federal Reserve cut interest rates three times in 2024.
The fund’s holdings in consumer staples and communication services were most additive to results. Likewise, utilities, real estate and financials holdings notched returns surpassing those of the overall portfolio.
Conversely, holdings in the materials, energy, information technology and health care sectors posted negative returns that lagged the portfolio during the period. Holdings in industrials also detracted from the fund’s total return.
