What companies were the biggest losers of 2013? It was a great year to be invested in the stock market overall, but there were a few major exceptions, particularly in retail stocks such as J.C. Penney (NYSE:JCP) and Sears Holdings (NASDAQOTH:SHLDQ). In this video, several Motley Fool analysts around Fool HQ sit down and give their nominees for the biggest losers. They talk Sears and J.C. Penney and trouble with CEO decisions, what was wrong with Nuance Communications (NASDAQ:NUAN), why lululemon athletica (NASDAQ:LULU) should never have blamed its customers when it sold see-through pants, and why Abercrombie & Fitch (NYSE:ANF) can seem to do no right.
