Short interest figures for the middle of October were released last week. The table below lists the 25 stocks in the S&P 500 that have the highest short interest as a percentage of float. Topping the list this month is a who's who of some of the most controversial stocks in the market. With a short interest level totaling nearly 50% of the stock's float, First Solar (NASDAQ:FSLR) tops the current list. Not far behind, shares of JCPenney (NYSE:JCP) have 43% of their float sold short. Besides these two, there are only six other stocks that have 25% or more of their float sold short (GME, SWY, PBI, NFLX, X, RRD).
One notable name on the list above is Chipotle (NYSE:CMG), which has had a rough month after reporting weaker than expected revenues last week. The stock also made headlines when hedge fund manager David Einhorn disclosed that he was short the stock. Judging by the chart below, either Einhorn has made a killing on his short bet or he has a lot of company. In just the last few months, the stock has seen its short interest as a percentage of float increase from 7.36% all the way to 11.54%.
