Who Was Benjamin Graham?

Benjamin Graham was a legendary investor, professor, and author. Born in 1894 in London and raised in New York, he became one of the most influential figures in finance. He is widely recognized as the father of value investing, a strategy that focuses on buying undervalued stocks.

Graham’s influence extends beyond his lifetime. His books and teachings continue to shape investment strategies today. One of his most famous students is Warren Buffett, who credits Graham for much of his success.

Graham’s Investment Philosophy

Graham believed that investing should be based on fundamentals, not emotions. Many investors buy stocks based on trends, speculation, or short-term movements. However, Graham argued that a successful investor should analyze a company’s financial health before making an investment.

His strategy focused on identifying undervalued stocks—companies whose stock prices were lower than their true worth. This approach allowed investors to minimize risk and maximize potential gains.

The Concept of Margin of Safety

One of Graham’s most famous ideas is the Margin of Safety. This principle suggests that investors should buy stocks at a significant discount to their intrinsic value. The Margin of Safety Formula helps determine this discount by comparing a stock’s intrinsic value to its market price.

A simple example is buying a house worth $300,000 for $200,000—this price cushion reduces risk. The same applies to stocks: the larger the margin of safety, the lower the risk of loss, even if the market declines.

How Graham Developed the Margin of Safety

Graham’s investment philosophy was shaped by real-world experience. He lived through the 1929 stock market crash, where many investors lost everything. He saw how speculation and overconfidence led to financial disasters.

As a result, he developed a systematic approach to investing. He focused on buying companies with strong financials at discounted prices. His research showed that stocks purchased with a high margin of safety had a better chance of generating profits over time.

The Intelligent Investor – Graham’s Most Famous Book

Graham wrote several books, but his most famous work is The Intelligent Investor, first published in 1949. It remains one of the most important books on investing.

In this book, Graham explains the difference between investing and speculating. Investors analyze companies and buy for the long term, while speculators try to predict short-term price movements. He strongly discouraged speculation, as it often leads to losses.

One of the book’s core lessons is the importance of staying rational. Graham warned against reacting emotionally to stock market fluctuations. Instead, he advised investors to focus on a company’s fundamentals and its margin of safety.

Benjamin Graham’s Influence on Warren Buffett

One of Graham’s most successful students is Warren Buffett, the billionaire investor and CEO of Berkshire Hathaway. Buffett studied under Graham at Columbia Business School and later worked for him.

Buffett has said that The Intelligent Investor is “by far the best book on investing ever written.” He adopted many of Graham’s principles, especially the idea of buying stocks below their intrinsic value.

While Buffett later adapted his approach, moving toward quality businesses with strong growth potential, he still credits Graham for teaching him the foundation of smart investing.

Graham’s Legacy in Value Investing

Benjamin Graham’s influence on the investment world is enormous. His principles are still widely used by individual and professional investors. The value investing strategy remains popular, especially among those who prefer long-term, stable returns over speculative gains.

Many top investors, including Seth Klarman, Charlie Munger, and Howard Marks, follow Graham’s teachings. His margin of safety approach is considered one of the most effective ways to build wealth while managing risk.
