Margin of Safety – The Secret to Understanding the Value Investing Strategy

The single most important concept in all of investing, according to Benjamin Graham and later confirmed by his star student, Warren Buffett, comes down to three simple words: Margin of Safety. What is the margin of safety? How do you calculate it? How important is it to developing a successful value investing strategy? As you’ll see in a moment, the theory behind value investing is that the ultimate return you earn on your investments will be closely related to the size and quality of the margin of safety you build in to your purchasing decisions, whether you are buying shares of Coca-Cola or building a hotel.

In addition to penning several of the most important value investing books in history, Benjamin Graham, the father of value investing, was one of the two partners in the Graham Newman Corporation, the investment fund through which he put money to work. It was at this firm that Warren Buffett worked early in his career, learning from the master. As he amassed an astounding investing record, Graham divided his portfolio into several categories, or “operations”. These served value investing students well for more than seventy years and some still have value today.
