- Parnassus Mid Cap Growth Fund (PFPRX) is an actively managed open-end mutual fund that seeks capital appreciation by investing at least 80% of its net assets in mid-sized growth companies, typically maintaining a high-conviction portfolio of 35 to 45 high-quality, fast-growing U.S. mid-cap stocks with healthy balance sheets, durable competitive advantages, strong management teams, and sustainable business practices; it may allocate up to 20% to smaller- or larger-capitalization companies and emphasizes leaders in attractive industries such as technology, financial services, and life sciences tools, with top holdings including Teradyne Inc., Robinhood Markets Inc., KLA Corp., and Guidewire Software Inc. Launched on April 30, 2015, the institutional share class (PFPRX) is managed by Parnassus Investments, LLC, an employee-owned investment management firm founded in 1984 and headquartered at One Market Street, Suite 1600, San Francisco, California, which specializes in responsible investing across equity strategies including large-cap core, growth, value, mid-cap, and international funds, with total firm assets under management exceeding $45 billion as of late 2024. The fund targets institutional and retail investors seeking mid-cap growth exposure with a focus on asymmetric return potential, aiming to capture the sector's upside while mitigating downside through quality selection, and operates primarily in U.S. markets while allowing limited non-U.S. stock exposure of around 4%.
In recent developments, the fund reported assets of approximately $863 million as of November 2025, distributed long-term capital gains of $4.24 per share in December 2024, and issued 2025 long-term capital gain distribution estimates ahead of final payouts on December 5, 2025; during Q1 2025, it capitalized on market volatility to initiate eight new high-conviction positions in innovative stocks, while in Q2 2024 it strategically exited holdings in Block Inc., Copart Inc., and Biomarin Pharmaceutical Co. and added positions in BILL Holdings Inc. and Western Digital Corp. Parnassus Investments, the fund's adviser and a majority-owned affiliate of Affiliated Managers Group since 2021, received the 2025 CIO Magazine Award for Public Equity, published its 2025 Sustainability & Stewardship Report highlighting chemical safety initiatives and engagements with companies like Advanced Micro Devices and FedEx on science-based targets, and continued expanding its product lineup with ETFs such as the Parnassus Core Select ETF (PRCS) and Value Select ETF (PRVS). These updates reflect ongoing portfolio optimization, enhanced stewardship practices, and firm-level recognition amid a focus on AI-driven trends, life sciences rebound, and mid-cap market leadership beyond mega-cap dominance.
