📖Howard Marks
Sell Discipline
Selling well requires discipline when things look good.
The hardest part of investing isn't buying at the bottom — it's selling when things are going well and prices exceed intrinsic value.
🏠 Everyday Analogy
📖 Core Interpretation
In Sell Discipline, Howard Marks focuses on the gap between price and value. Returns come from paying less than what a business is worth, not from guessing short-term market moves.

❓ Why It Matters
Ignoring valuation turns even good companies into poor investments. Overpaying compresses future returns and leaves little margin when assumptions are wrong.
🎯 How to Practice
Estimate intrinsic value with conservative assumptions, set clear buy ranges, and act only when price offers a meaningful discount with acceptable downside.
⚠️ Common Pitfalls
Confusing a low price with true cheapness
Using one metric without business context
Overly optimistic assumptions that erase margin of safety
