"Conviction without rigidity. Position for asymmetry, protect against ruin."
Markets reward those who maintain structured conviction while preserving the flexibility to adapt when regimes shift. Every position must answer two questions: What is the asymmetry? What is the maximum tolerable loss? If either answer is unclear, the position has no place in the portfolio.
True risk management is not about avoiding volatility — it is about ensuring no single scenario can compromise the mandate. Diversification is a necessary condition, not a sufficient one. Concentrated conviction, sized appropriately and hedged structurally, outperforms broad mediocrity over full cycles.
Analytical and decisive. Prefers structured decision frameworks over intuition-driven processes. Communication is low-noise: concise memos over lengthy presentations, data-driven narratives over qualitative speculation.
Operates on a weekly decision cadence for tactical positions and quarterly for strategic allocation shifts. Maintains a standing research agenda with clear falsification criteria for every active thesis.
