Even though the benchmark S&P 500 stock index has ended 2011 unchanged, that flat performance is enough to beat shares of Warren Buffett's Berkshire Hathaway.
Berkshire Class A ended the year at $114,755 per share, a drop of 4.7 percent from its 2010 close.
Class B shares fell a little bit more, ending the year with a 4.8 percent decline.
