U.S. equities rebounded sharply in Q2, with the Russell 3000 gaining 15.4%, supported by AI infrastructure spending, strong earnings, and easing Middle East tensions. Technology led the rally as semiconductors recovered, while Energy and defensive sectors lagged. The portfolio returned 12.1% gross and 11.8% net compared with a 20.3% gain in the Russell 2500 Index.

Looking ahead, resilient earnings and AI productivity support a constructive outlook, but negative hyperscaler cash flow, sticky inflation, geopolitical risks, index concentration, and elevated valuations warrant caution. The strategy continues to emphasize quality, downside protection, and active management. Additionally, reviewing the Fund's top five holdings could also highlight its best ideas for 2026.
