4Factor

A 25-year global equity capability combining quantitative insight and fundamental research to deliver disciplined, repeatable investment outcomes.

Fundamental investors, harnessing technology

The 4Factor team invests across developed and emerging markets through Global, International, European, Emerging Market Equity, Asia, and China strategies.

The team’s approach combines machine learning with human judgement. The proprietary alpha model drives idea generation and guides fundamental research, highlighting where market behaviour or changes in company fundamentals may create opportunity. It helps direct research toward the areas with the greatest potential to add value. Core portfolios are built from diversified, company-level insights, with active risk driven by fundamentals rather than broad style or macro factors.
