American International Group Inc.

Industry: Multiline insurance

Total return: -52.0 percent

In 2008, AIG (AIG) was bailed out by U.S. taxpayers, who still own 77 percent of the insurer. The stock recovered 92 percent of its value in 2010 but gave up all those gains in 2011. On Nov. 4, Chief Executive Officer Robert Benmosche cited a "perfect storm" of tough market conditions and natural disasters that required higher insurance payouts.
