Strategy Overview
A high-conviction, concentrated portfolio of growth companies with asymmetrical risk/rewards. Select Growth reflects our highest conviction ideas—sized to drive alpha while prudently managing risk.
Investment Approach
Select Growth Equity is built on the belief that investing in a concentrated portfolio of growth companies with asymmetrical risk / reward profiles offers the best opportunity to maximize return while managing risk responsibly. The portfolio aims to strike a deliberate balance between high-quality compounders with accelerating earnings growth and catalyst-driven growth opportunities-believing that thoughtful exposure to both enhances consistency and long-term results.
The strategy is managed by Will Muggia, President, CEO & CIO, and supported by the firm’s tenured Investment Team — a group of sector specialists with deep domain expertise across the market cap spectrum. Ideas are sourced through Westfield’s deep sector coverage and refined through collaborative discussion.
Key attributes of the approach include:
- Fundamental stock selection focused on growth inflections and valuation discipline
- A deliberate mix of long-term compounders and near-term opportunities
- Concentrated portfolio of 35 or fewer holdings, reflecting our best thinking
- Disciplined risk framework guiding portfolio construction
