Explore value investing, the Graham-Dodd security-analysis method, and the documented contributions of Benjamin Graham and Warren Buffett.
Value Investing compares a security’s market price with a defensible estimate of value. The estimate may rely on assets, normalized earning power, future cash flow, distributions, comparable securities, or several methods. A low P/E or P/B ratio can identify a candidate, but it cannot establish value without understanding the business and its claims.
The Graham and Dodd Method of Investing provides the historical security-analysis foundation. It extends beyond common stocks to bonds and preferred shares, with attention to financial strength, claim priority, conservative appraisal, and a margin of safety.
