“Volatility is not a measure of risk…. Risk comes from the nature of certain kinds of businesses. It can be risky to be in some businesses just by the simple economics of the type of business you’re in, and it comes from not knowing what you’re doing. And if you understand the economics of the business in which you are engaged, and you know the people with whom you’re doing business, and you know the price you pay is sensible, you don’t run any real risk.” —Warren Buffett.
