Drew Gillanders on Developing Investment Judgement

Commercial pragmatism and self-reflection serve as the foundational skills for success in high-stakes investment environments. Drew Gillanders, Head of Fundamental Equities for Europe at Citadel, emphasizes that professional growth requires understanding market differentiation while simultaneously analyzing one's personal reaction to risk and loss. Citadel’s organizational success stems from an intentional, talent-led approach to team building, where decision-making relies on flexible risk guidelines rather than rigid quantitative limits. This model necessitates a deep understanding of team processes and individual judgment. Learning is structured through osmotic desk-side mentorship and a codified progression system that accelerates high performers. The effectiveness of this internal development is evidenced by the fact that 50% of the firm's portfolio managers began their careers at the entry level, thriving in an environment defined by constant peer-driven aspiration and curiosity.
