Learn from Past Sells

🌿 Intermediate★★★★☆

Post-mortem every sell decision to improve.

💬

After every sell, review the outcome. Did you sell too early, too late, or at the right time? Post-mortems on sell decisions improve future judgment.

🏠 Everyday Analogy

Market cycles resemble seasons: planting, growth, harvest, and winter. Using one strategy in every season leads to repeated mistakes.

📖 Core Interpretation

Li Lu sees markets as cyclical rather than linear. Understanding cycle position improves risk-taking decisions more than trying to call exact tops and bottoms.
💎 Key Insight:Reviewing sell decisions sharpens future timing.

❓ Why It Matters

Ignoring cycles repeats the same mistakes: excessive optimism at peaks and excessive pessimism near troughs. Context matters for position sizing.

🎯 How to Practice

Monitor credit, valuation, earnings, and sentiment signals; reduce aggressiveness in euphoric phases and preserve flexibility in fearful phases.

⚠️ Common Pitfalls

Treating short rebounds as full cycle turns
Extrapolating peak conditions indefinitely
Becoming maximally defensive near valuation troughs
