In the final quarter of 2025, the Baron Discovery Fund registered a modest gain of 0.19% for its Institutional Shares, falling short of the Russell 2000 Growth Index by 1.03%. This period was characterized by a market environment where less financially robust companies, often burdened by high debt and demonstrating weaker profitability, along with those exhibiting short-term price momentum, tended to outperform. Amidst these conditions, the fund's strategic selections and their individual performances stood out. Notably, Exact Sciences Corporation became the subject of a significant acquisition offer from Abbott Laboratories (ABT), proposing $105 per share in cash. Concurrently, Casella Waste Systems, Inc. garnered attention for its remarkable transformation over the past decade, evolving into a leading entity within the waste management sector with rapid growth. JFrog Ltd., another key holding, maintained its reputation as a standard-setter in binary management, catering to an extensive client base of more than 7,000 organizations. These developments collectively underscore the dynamic shifts in market preferences and the strategic positioning of the fund's core investments.
Quarterly Performance and Market Dynamics
The fourth quarter of 2025 saw the Baron Discovery Fund's Institutional Shares achieve a return of 0.19%, which represented an underperformance of 1.03% compared to the Russell 2000 Growth Index. This period highlighted a market preference for companies with higher levels of debt and lower profitability, as well as those demonstrating short-term price momentum. The fund, however, maintains a commitment to investing in high-quality businesses with strong fundamentals, anticipating long-term superior performance.

The fund's managers believe that a disciplined approach centered on fundamental analysis and long-term potential will ultimately deliver value to its shareholders, distinguishing it from market segments driven by transient trends and speculative trading.
