Episode notes
Don't Overweight Dealer Flow Narratives
- Market makers have hedging expertise and long experience; dealer-flow explanations often overstate the tradable payoff for outsiders.
- Small measurable effects exist, but they rarely scale into simple, reliable retail strategies.
Pick Predictable Problems, Not Grand Forecasts
- Forecasting accuracy depends on choosing stable, predictable regimes and problems, not grand long-term narratives.
- Pick small, tractable predictions (e.g., VIX cheapness) over complex geopolitical long-range calls.
Let Humility Guide Position Sizing
- Be humble about daily certainty and let long-term small edges drive sizing rather than reacting to noisy P&L swings.
- Scale by conviction and historical edge, not by short-run luck.
