Strategic Resilience: Parnassus Mid Cap Fund Adapts to Market Headwinds

Quarterly Performance Review: Underperforming the Benchmark Amid Sectoral Challenges

During the first quarter of 2026, the Parnassus Mid Cap Fund (Investor Shares) posted a net return of -2.35%, which fell short of the Russell Midcap Index's 1.29% gain. The primary factors contributing to this underperformance were the fund's investments in the Industrials, Materials, and Health Care sectors, which did not perform as expected. Additionally, the fund's limited exposure to the Energy sector, which saw considerable gains during this period, further impacted its relative returns.

Market Dynamics: Shifting Sentiments and Economic Headwinds

The beginning of 2026 saw a notable shift in equity markets. Initial investor optimism, fueled by the accelerating artificial intelligence trend and expectations of more lenient monetary policies, gave way to a more cautious outlook. Geopolitical instability and a tightening of financial conditions emerged as dominant themes, tempering market enthusiasm and leading to increased volatility. This broader market environment presented both challenges and opportunities for active fund management.

Strategic Portfolio Adjustments: Seizing Opportunities Amidst Volatility

In response to the market's fluctuating conditions, the Parnassus Mid Cap Fund proactively leveraged the increased volatility to refine its portfolio. The investment team strategically reallocated capital, focusing on companies with more robust growth potential. This involved divesting from certain positions and initiating new ones that were deemed better aligned with the fund's long-term objectives and more resilient to macro-economic pressures.

Investment Philosophy: Upholding Discipline and Fundamental Analysis

The Parnassus Mid Cap Fund continues to adhere to its core investment philosophy, emphasizing disciplined, fundamentals-driven analysis. The fund's managers are committed to identifying and investing in durable businesses characterized by strong financial health, sustainable competitive advantages, and reasonable valuations. This steadfast approach is designed to generate solid long-term returns for its investors, irrespective of short-term market fluctuations.
