Berkshire Hathaway (NYSE: BRK.A)(NYSE: BRK.B) CEO Warren Buffett isn't infallible, but he does have a knack for running circles around Wall Street. Since taking the reins, the 3,787,464% aggregate return for Berkshire's Class A shares (BRK.A) is more than 153 times greater than the 24,708% total return, including dividends paid, for the benchmark S&P 500. The Oracle of Omaha's overwhelming success is attributed to his patience as an investor, his willingness to buy cyclical companies and dividend stocks, and his rather narrow research focus, which makes him an expert in a handful of sectors and industries.
