Benjamin Graham, the greatest investment advisor of the twentieth century, introduced the philosophy of "value investing" through his book The Intelligent Investor. The book teaches readers to develop long-term investment strategies and shields them from substantial errors. Despite being originally published in 1949, the book remains relevant today, and the revised edition includes updated commentary by financial journalist Jason Zweig. Zweig draws parallels between Graham's examples and today's financial headlines, giving readers a more thorough understanding of how to apply Graham's principles. The book is considered an indispensable guide to reaching financial goals and is a must-read for anyone interested in the stock market.
