📖Stanley Druckenmiller
Avoid Big Losses
Never lose big because recovering from large losses requires doubling capital.
Never lose big money. A 50% loss requires a 100% gain to recover. Protect your capital.
🏠 Everyday Analogy
📖 Core Interpretation
Stanley Druckenmiller treats survival as the first objective. Limiting permanent capital loss, controlling leverage, and avoiding single-point failure are prerequisites for long-term compounding.
💎 Key Insight：Druckenmiller's cardinal rule is capital preservation. A 50% loss requires a 100% gain just to break even - the math is brutal. Large losses destroy compounding and can end investment careers. Protecting against catastrophic losses is more important than maximizing gains. This means sizing positions appropriately, using stop losses, and cutting positions quickly when the thesis breaks. Many talented investors blow up by taking excessive risk in pursuit of returns. Survival comes first; returns come second. Capital preservation allows you to stay in the game for the next opportunity.
