The fund delivered a +3.22% return in the fourth quarter of 2025, performing roughly in line with both the Russell 2500 Value Index (+3.15%) and the Russell 2000 Value Index (+3.26%), as U.S. equities posted a modest quarterly gain despite earlier volatility marked by a sharp April sell-off, an extended government shutdown, and rising job cuts. For the trailing one-year period, the Fund advanced 14.15%, outperforming the Russell 2500 Value Index’s +12.73% and the Russell 2000 Value Index’s +12.59% return, while its 5- and 10-year average annual returns stood at +9.36% and +9.51%, respectively. Management attributed performance to resilient corporate earnings, easing inflation, and rising expectations for more accommodative monetary policy. Continued enthusiasm around artificial intelligence and cloud infrastructure also supported markets, although gains remained concentrated in a narrow group of large-cap stocks. Looking ahead to 2026, the firm maintains a measured and cautious outlook. It pointed to geopolitical risks, fiscal constraints, labor market dynamics, and elevated market concentration as potential sources of volatility. At the same time, management reaffirmed its long-term, bottom-up approach, emphasizing strong balance sheets, durable fundamentals, and valuation discipline to navigate shifting market leadership.
