“The key to [Benjamin] Graham’s approach to investing is not thinking of stocks as stocks or part of a stock market. Stocks are part of a business. People in this room own a piece of a business. If the business does well, they’re going to do all right as long as they don’t pay way too much to join into that business…. It doesn’t make any difference to us whether the volatility of the stock market…averages a half a percent a day or a quarter percent a day or 5 percent a day. In fact, we’d make a lot more money if volatility was higher, because it would create more mistakes in the market. So volatility is a huge plus to the real investor…. As an investor, you love volatility. Not if you’re on margin, but if you’re an investor you aren’t on margin. And if you’re an investor, you love the idea of wild swings because it means more things are going to get mispriced.”
—Warren Buffett (1997 Berkshire Hathaway Annual Meeting).
