The Intelligent Investor
by Benjamin Graham
Editorial review
Warren Buffett has called this the best book on investing ever written, and serious investors continue to agree. The 1973 revised edition with Jason Zweig's modern commentary remains the standard.
AI-generated summary
Graham, the founding figure of value investing, distinguishes between investment and speculation, introduces 'Mr. Market' as a metaphor for short-term price volatility, and argues for a margin-of-safety discipline that has shaped the careers of his most famous students.
Key takeaways
- 1
Investment requires a margin of safety — both numerical and temperamental.
- 2
Mr. Market is bipolar; treat his daily quotes as offers, not verdicts.

- 4
Knowing what you don't know is half of competence.
