Quick Take

"Baron Health Care Fund gained 4.02% net in Q3 2026, driven by a cyclical rebound across overweight life sciences tools holdings, while initiating turnaround stakes in Biogen and Humana and exiting 14 positions."

Executive Summary

During the third quarter of 2026, Baron Health Care Fund advanced 4.02% net of fees for Institutional Shares (and 3.91% net for Retail Shares), trailing the Russell 3000 Health Care Index return of 6.19% while outperforming the broad-market Russell 3000 Index return of 1.40%. Year-to-date, the Fund has gained 8.38% net of fees versus 11.61% for the health care benchmark. Relative performance was weighed down by stock selection in biotechnology, which detracted 235 basis points, driven by the absence of Moderna and clinical setbacks in Xenon Pharmaceuticals and Cytokinetics. Conversely, the Fund benefited substantially from a large overweight in life sciences tools and services, which added 190 basis points to relative performance as end-market demand rebounded. Cash and cash equivalents stood at 3.0% of net assets at quarter-end. The macroeconomic and sector backdrop reflected diverging dynamics across sub-industries. Life sciences tools staged a broad recovery supported by an inflection in biopharma funding, expanding clinical pipelines, lab-instrument replacement cycles, and recovering demand in China following a new five-year pharmaceutical development plan. Meanwhile, managed care and biopharmaceutical sectors contended with headwinds, including mid-term election policy overhangs, Medicare Advantage Star Rating uncertainties, and high-profile cardiovascular clinical trial failures, even as underlying demand for health care innovation and reshoring of domestic manufacturing remain robust. Portfolio turnover was pronounced during the quarter as the manager initiated 4 new holdings and fully exited 14, bringing the total position count to 33. The Fund established new long stakes in biopharmaceutical turnaround Biogen and pure-play Medicare Advantage insurer Humana, citing attractive risk-reward asymmetric recovery potential. The Fund also scaled positions in large-cap pharmaceutical leaders Johnson & Johnson, Merck, and Vertex Pharmaceuticals, while divesting AstraZeneca, Xenon Pharmaceuticals, Gilead Sciences, and Madrigal Pharmaceuticals to mitigate regulatory and competitive risks.

Market Conviction

Conviction is high, demonstrated by a focused 33-holding portfolio where the top 10 positions account for 61.3% of net assets, led by a dominant 14.3% allocation to Eli Lilly. The manager also took decisive action by fully exiting 14 holdings that experienced broken clinical hypotheses or elevated regulatory risks, while affirming personal co-investment in the Fund alongside shareholders.

Growth Outlook

The outlook is constructive, highlighted by the cyclical re-acceleration in life sciences tools, recovering biopharmaceutical funding, and attractive de-rated valuations in medical devices. While macroeconomic and election-related policy concerns are acknowledged, the manager expects durable secular tailwinds to support sector compounding.

DefensiveAggressive

Balanced (70%)

Risk Appetite

The portfolio is positioned net long with minimal cash (3.0%) and actively deploying into turnaround and margin recovery stories such as Humana and Biogen. Concurrently, the manager actively reduced risk by selling down names facing safety issues or clinical readout uncertainties like Xenon and Madrigal.

Capital Deployment

Capital deployment was moderate to active, with cash maintained at a lean 3.0% as capital from 14 complete liquidations was recycled into 4 new high-conviction positions and additions to bellwether holdings like JNJ, Merck, and Vertex.

Forward Guidance

Guidance reflects an active buying bias toward valuation-compressed sub-sectors, specifically initiating positions in beaten-down managed care and biotechnology while capitalizing on life sciences tools orders.
