Short interest figures for the end of October were released earlier this week and with that we updated our semi-monthly report on trends in short interest among sectors, groups, and individual stocks. The table below lists the 29 stocks in the S&P 1500 which have more than 30% of their free-floating shares sold short. For each company, we have also included its performance since the end of October. As has been the case for well over a year now, the most heavily shorted stocks are still performing poorly. Of the 29 names listed, their average decline month to date is -0.70% (median: -0.24%) compared to a decline of just 0.14% for the S&P 1500. Breadth among the 29 names is mixed with fourteen stocks up and fifteen down. Of the fifteen stocks that have traded down, a third of them are down by at least 10%. In terms of market cap, most of the names with the highest short interest are small cap stocks, but a handful of large cap stocks also made the list. These include GameStop (GME), Chesapeake (CHK), and Transocean (RIG).
