Warren Buffett is without question one of the greatest investors of all time. His track record at Berkshire Hathaway (NYSE: BRK-A) (NYSE: BRK-B) (and even before Berkshire) proves it. Exelixis (NASDAQ: EXEL) is one of the greatest winners in the stock market in recent history. Its stock-price appreciation proves it -- with gains of 1,500% in just three years.
