The Intelligent Investor by Benjamin Graham – Paperback

About the Book

First published in 1949, Benjamin Graham’s The Intelligent Investor laid the foundation for value investing — the philosophy Warren Buffett has followed throughout his career. The book teaches readers to separate investing from speculation, introduces the enduring concept of “Mr. Market” as a metaphor for market irrationality, and lays out Graham’s principle of “margin of safety” for protecting capital against loss. This revised edition preserves Graham’s original text in full, with chapter-by-chapter commentary from financial journalist Jason Zweig that updates the examples and data for the modern market while keeping Graham’s core principles intact.
