Stock Market Winners and Losers

The U.S. stock market returned almost nothing to investors in 2011. As of early December, the Standard & Poor's 500 index had netted 0.9 percent -- and actually lost 1 percent if dividends aren't included.

Such poor overall performance hides some wide variations: 80 stocks in the S&P 500 returned 20 percent or more in 2011, while 43 lost more than a third of their value.

Bloomberg Rankings analyzed S&P 500 returns as of Dec. 2 to determine which stocks were best and worst to shareholders in 2011. Their results follow, starting with 2011's 10 best performers.
