Ron Baron's BAMCO Portfolio: A Q1 2026 Update Analysis
Ron Baron's BAMCO 13F portfolio is a fascinating case study in long-term investing, with a focus on core growth holdings and a commitment to holding positions for the long haul. In Q1 2026, the portfolio decreased to $33.13 billion, with 350 positions and 33 core holdings exceeding 0.5% of the total.
Tesla (TSLA): The Flagship Holding
What makes this particularly fascinating is Tesla's enduring presence as the largest stake in the portfolio, accounting for 13.39% of the total. Despite a marginal increase this quarter, Tesla's long-term bullish outlook remains intact. Baron's faith in Tesla is a testament to his belief in disruptive innovation and the potential for electric vehicles to revolutionize the automotive industry.
Core Growth Holdings: FactSet (FDS), Guidewire (GWRE), Kinsale Capital (KNSL), Choice Hotels (CHH)

These companies represent a diverse range of sectors, from software solutions to hospitality, and their strong performance potential aligns with BAMCO's long-term investment strategy.
Profit-Taking and Rebalancing: Gartner (IT), CoStar (CSGP), Idexx Labs (IDXX), Mettler Toledo (MTD)
One thing that immediately stands out is the selective profit-taking in Gartner, CoStar, Idexx Labs, and Mettler Toledo.
