As Warren Buffett, his most famous student, explains, “There are three important principles to Graham’s approach.” The first is simply looking at stocks as businesses, which “gives you an entirely different view than most people who are in the market.” The second is the margin-of-safety concept, which “gives you the competitive edge.” And the third is having a true investor’s attitude toward the stock market. “If you have that attitude,” says Buffett, “you start out ahead of 99 percent of all the people who are operating in the stock market—it is an enormous advantage.”
