A copy of the Q2 2026 investor letter can be downloaded here. In the quarter, equity markets posted strong returns as resilient economic growth and robust corporate earnings supported investor sentiment, although AI-related companies continued to dominate market leadership. Technology was the strongest-performing sector, while industrials also advanced and energy lagged as oil prices declined. The Fund returned 7.92% and the Russell Midcap Index returned 13.83%. Health care holdings were the largest positive contributor, supported by strength across managed care, diagnostics, and life sciences. However, stock selection and an underweight position in information technology remained the main relative headwinds. The strategy maintained limited exposure to highly valued semiconductor and memory companies, reflecting concerns that current valuations assume an extended period of elevated AI spending. It also continued to assess software and services businesses individually based on how AI may affect their long-term competitive positions. Management emphasized higher-quality companies, attractive valuations, capital preservation, and durable long-term compounding while remaining cautious about elevated valuations, concentrated leadership, and the sustainability of the current AI investment cycle.
