In this series, we take a look at the 25 stocks on the S&P 500 Index (SPX) that have turned in the worst performance during the past decade -- what went wrong, and what happens next. (See all 25).

While financial-services firms have been dragged down as a group for more than a year, few have flamed out with the spectacular ferocity of municipal bond insurer MBIA Inc. (NYSE: MBI).
