📖Benjamin Graham

The Intelligent Investor

🌿 Intermediate★★★★★

The intelligent investor exploits market emotions by buying when others panic and selling when others are euphoric.

💬

The intelligent investor is a realist who sells to optimists and buys from pessimists.

— _The Intelligent Investor_，1949

🏠 Everyday Analogy

Just as a savvy housewife picks up bargains when vendors are eager to close their stalls at the market, and calmly observes when others rush to buy, the stock market operates on the same principle. True investment wisdom lies in buying when everyone is panicking and selling, and selling when everyone is euphorically chasing rallies.

📖 Core Interpretation

A wise investor is a realist, who buys in times of pessimism and sells in times of optimism.
💎 Key Insight：Rationality is the investor's greatest edge. When the crowd is fearful, assets are priced below intrinsic value; when euphoric, above it. The intelligent investor is not contrarian for its own sake but acts on valuation discipline that naturally opposes crowd sentiment at extremes.

🎙️ Master's Voice

Obvious prospects for physical growth in a business do not translate into obvious profits for investors.
Graham warned that growth was often already priced in. Obvious growth stories rarely offered good value because everyone saw them.

📚 Case Studies

1
Nifty Fifty Overvaluation (1973)
Popular blue-chip growth stocks traded at extreme P/E ratios, seen as 'one-decision' stocks that could be bought at any price.
✨ Outcome：A Graham-style value investor avoided overpaying, preserved capital during the 1973–74 bear market, and later bought quality stocks at far lower prices.
2
Dot-Com Bubble Discipline (2000)
Technology and internet stocks soared despite little or no earnings, while many established companies traded below intrinsic value.
✨ Outcome：A Graham-style investor shunned speculative tech names, bought undervalued, profitable firms, and outperformed when the bubble burst and value stocks recovered.
