You're dealing with a lot of silly people in the marketplace; it's like a great big casino and everyone else is boozing. If you can stick with Pepsi, you should be OK.
Warren BuffettIf you understood a business perfectly and the future of the business, you need very little in the way of a margin of safety.
Warren BuffettThere are three important principles to Graham's approach. [The first is to look at stocks as fractional shares of a business, which] gives you an entirely different view than most people who are in the market. [The second principle is the margin-of-safety concept, which] gives you the competitive advantage. [The third is having a true investor's attitude toward the stock market, which] if you have that attitude, you start out ahead of 99 percent of all the people who are operating in the stock market - it's an enormous advantage.
