Before Munger, Warren Buffett followed Benjamin Graham’s “cigar-butt” investing—buying cheap, mediocre stocks for short-term gains. Munger shifted this approach, advocating:
“It’s far better to buy a wonderful company at a fair price than a fair company at a wonderful price.”
Key Data & Shifts Munger Brought to Investing
| Metric | Before Munger | After Munger’s Influence |
|---|---|---|
| Investment Horizon | Short-term flips | Long-term holds (decades) |
| Business Focus | Cheap stocks | High-quality moat businesses |
| Key Holdings | Textile mills | Coca-Cola, Apple, See’s Candies |
| Performance Impact | Moderate returns | 20%+ annualized returns (Berkshire) |
Munger’s Core Investing Principles
- Economic Moats Matter – Companies like Coca-Cola (KO) and Apple (AAPL) dominate due to brand power and pricing control.
- Compounding Over Trading – Berkshire’s long-term holds (e.g., American Express since 1964) prove time beats timing.
- Margin of Safety – Buying below intrinsic value, but only for great businesses.

3. The 200-Week Moving Average Strategy: Munger’s Hidden Technical Edge
Though a fundamental investor, Munger acknowledged:
“If you buy great companies at the 200-week moving average, you’ll beat the market.”
Case Studies: Stocks That Rebounded from 200-Wk MA
| Stock | 200-Wk MA Bounce Year | Subsequent 1-Year Return |
|---|---|---|
| Apple (AAPL) | 2016, 2019, 2022 | +45%, +82%, +52% |
| Nvidia (NVDA) | 2022 | +220% (AI boom) |
| Microsoft (MSFT) | 2020 (COVID crash) | +48% |
Why This Works:
- The 200-week MA acts as a support level for elite stocks.
- Buying at this point reduces risk while capturing upside.
