A copy of the letter can be downloaded here. During the quarter, the Fund underperformed its benchmark, the Russell Mid Cap Growth Index, primarily due to unfavorable stock selection, even as U.S. equity markets advanced on moderating inflation, robust earnings, and continued enthusiasm around artificial intelligence-driven investment. Looking ahead, the managers highlighted a cautiously constructive outlook, noting that while geopolitical risks and policy uncertainty persist, broadening market leadership beyond mega-cap growth, sustained corporate capital expenditure, and AI-led innovation could support returns, reinforcing the need for active and flexible positioning.
