"Baron Health Care Fund delivered solid Q3 performance driven by strong biotechnology stock selection, particularly argenx and Insmed. The fund maintains conviction in GLP-1 leader Eli Lilly despite near-term setbacks, viewing the $150+ billion obesity/diabetes market as still early stage."
Baron Health Care Fund returned 5.39% in Q3 2025, performing in line with its healthcare benchmark. Strong stock selection in biotechnology drove most relative gains, led by argenx SE and Insmed Incorporated, which benefited from better-than-expected drug sales and regulatory approvals respectively. AI-driven healthcare companies like RadNet and Heartflow also contributed positively. The fund maintains significant exposure to GLP-1 therapies through its largest holding Eli Lilly, despite near-term disappointment with orforglipron trial results. The manager expects the GLP-1 class to represent a $150+ billion market opportunity. Medical device holdings faced headwinds from hospital financial pressures and increased competition in key markets like pulsed field ablation. The fund added 16 new positions during the quarter, taking advantage of attractive valuations. Looking forward, the manager sees the Pfizer-Trump Administration agreement as a positive template that should limit regulatory overhang. Long-term secular drivers including aging demographics, chronic disease prevalence, and technological advances support continued optimism for the healthcare sector.
