Value Investing Principles

The "margin of safety" is the difference between a security's intrinsic value and its market price. Graham advises only purchasing securities when they are available at a significant discount to their intrinsic value, providing a buffer against errors in analysis or unforeseen events.

This principle helps protect investors from permanent capital loss and is considered the most important concept in Graham's investment philosophy.

Graham describes the stock market as "Mr. Market," an emotional business partner who offers to buy or sell shares every day at different prices based on his mood rather than rational analysis.

The intelligent investor should take advantage of Mr. Market's mood swings, buying when he's pessimistic (prices are low) and selling when he's optimistic (prices are high), rather than being influenced by his emotions.

Graham distinguishes between two types of investors:

• Defensive (Passive) Investor: Seeks safety, freedom from effort, and reasonable returns.
• Enterprising (Active) Investor: Willing to devote time and effort to security selection for superior returns.

Graham emphasizes that both approaches can be successful, but investors must honestly assess their time, interest, and expertise before choosing their path.

Intrinsic value is the actual value of a company or asset, based on an analysis of its financial statements, competitive position, management quality, and growth prospects.

Graham teaches that market prices fluctuate around intrinsic value over time. The intelligent investor focuses on determining intrinsic value rather than predicting price movements.

"Price is what you pay, value is what you get." This principle emphasizes that the market price of a security is not necessarily equal to its value.

The intelligent investor seeks to buy securities when their price is significantly below their value, creating the margin of safety that protects against downside risk.
