📖Paul Tudor Jones

Control Your Emotions

🌳 Advanced★★★★★

Assume every position is wrong until proven otherwise.

💬

Every day I assume every position I have is wrong. This removes the ego from trading. Never fall in love with a position.

— Market Wizards，1989

🏠 Everyday Analogy

Controlling emotions in trading is like being a pilot flying through a storm. The wind and thunder are your fear and greed, roaring outside the cockpit. If you stare at the lightning, you’ll panic and crash; if you keep your eyes on the instruments—your plan, rules, and risk limits—you can cut through the turbulence and land safely, regardless of the noise.

📖 Core Interpretation

Paul Tudor Jones highlights that many investment mistakes are psychological, not analytical. Managing behavior under stress is as important as finding ideas.
💎 Key Insight：This defensive mindset keeps you humble and alert. Don't get emotionally attached to positions or your analysis. The market doesn't care about your opinion. Be ready to exit immediately if the trade thesis breaks down. Constantly question your assumptions and watch for invalidating signals. This paranoid approach prevents devastating losses from stubbornly holding losing positions.
