Early Influences and Core Philosophies
Warren Buffett’s Graham-Inspired Approach
- Benjamin Graham’s Influence: Focused on buying undervalued stocks with a margin of safety.
- Cigar Butt Investing: Buying mediocre companies at deep discounts (e.g., Berkshire Hathaway itself was initially a struggling textile company).
- Key Metrics: Book value, P/E ratios, and net-nets (stocks trading below liquidation value).
Charlie Munger’s Qualitative Shift
- Rejected Pure Graham Approach: Argued that “a great business at a fair price is better than a fair business at a great price.”
- Focus on Moats: Preferred companies with durable competitive advantages (e.g., Coca-Cola, See’s Candies).
- Multidisciplinary Thinking: Applied psychology, economics, and business models to investing.

| Business Selection | Cheap but decent businesses | Exceptional businesses, even at higher prices |
| Diversification | Initially followed Graham’s diversification rule | Preferred concentrated bets (e.g., BYD, Costco) |
| Use of Leverage | Avoided debt, used insurance float | More open to leverage (e.g., Blue Chip Stamps) |
| Psychological Bias | More patient, avoided hype | More aggressive, embraced contrarian bets |

Psychological & Behavioral Differences

- Adapt or Die (Buffett’s shift into Apple shows evolution)
