Strategy Overview
A high-conviction portfolio designed to benefit from the long-term transformation of the U.S. health care system by investing in innovative, well-positioned companies driving efficiency, access, and improved patient outcomes.
Investment Approach
Our Health Care strategy is built to capture the long-term transformation of the U.S. health care system. We invest in high-quality companies driving innovation, advancing patient outcomes, and helping shift the system toward greater efficiency, access, and value. The portfolio is broadly diversified across the health care ecosystem.
While the health care sector can be dynamic and complex, our process is designed to remain grounded in fundamentals. We emphasize innovation with purpose, valuation awareness, and portfolio balance—seeking to capture secular growth while managing risk.
The strategy is managed by a seasoned portfolio management team with deep domain expertise and a bottom-up research approach. Matt Renna, Managing Partner & Head of the Health Care sector team, serves as lead portfolio manager alongside Will Muggia, President, CEO & CIO. Ideas are sourced through Westfield’s Health Care team and refined through collaborative discussion and disciplined analysis.
Key attributes of our approach include:
- Fundamental research with a focus on innovation, quality, and capital discipline
- Balanced exposure across sub-industries and market caps to capture the full opportunity set
- Concentrated portfolio of 30–50 holdings
- Disciplined risk framework guiding portfolio construction
