Strategy Overview
A high-conviction mid cap growth strategy targeting businesses with strong fundamentals and under-appreciated earnings potential. We aim to deliver consistent performance across cycles through deep research and disciplined execution.
Investment Approach
Mid Cap Growth Equity is built on the belief that stock prices ultimately follow earnings growth. We seek to identify businesses with strong fundamentals, underappreciated earnings potential, and durable competitive advantages — the companies we believe are best positioned to outperform over time.
The strategy is managed by Westfield’s Investment Committee — a tenured group of sector specialists with deep domain expertise across the market cap spectrum. Their focus on both secular and cyclical growth opportunities enables us to build a portfolio that is not only diversified across end markets, but also positioned to capture multiple drivers of earnings acceleration across market cycles.
Key attributes of our approach include:
- Bottom-up stock selection grounded in fundamental due diligence
- Balanced exposure for resilience across market cycles
- Concentrated portfolio of 55–65 holdings, reflecting our best thinking
- Disciplined risk framework guiding portfolio construction
