💬

A man who wants to catch fish needs to go where there are fish. A man who wants good investments needs to go where there are great businesses at fair prices.

— Psychology of Human Misjudgment,1995

🏠 Everyday Analogy

Valuation is like buying a house: the asking price reflects mood, but true value comes from structure, location, and long-term utility. Good assets still need sensible prices.

📖 Core Interpretation

In Fish Where the Fish Are, Charlie Munger 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.
💎 Key Insight:Efficiency in stock selection means looking in the right places.

❓ 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

📚 Case Studies

1
Dot-com Bubble Overconfidence (1999)
Investor fixated on 'internet will change everything' bought unprofitable dot-coms at any price, ignoring valuation, cash flows, and business quality.
✨ Outcome:Portfolio fell over 80% by 2002; many holdings went bankrupt, illustrating Munger’s warning about a single mental model dominating decisions.
2
Housing Market and Bank Stocks (2008)
Investor believed 'real estate always goes up' and that banks were safe due to diversification, buying highly leveraged financials before the crisis.
✨ Outcome:Severe losses as housing collapsed and bank shares plunged or were diluted, showing dangers of one-factor thinking and ignoring leverage and downside risk.
