Traders love the volatility that usually accompanies stocks with high levels of short interest. When the market is in rally mode, stocks with high short interest usually get an extra boost to the upside because of short covering. When the market is declining, these same stocks usually underperform because there are shorts piling on to the regular long sellers.
Below is a list of the 50 most heavily shorted stocks in the country (in the Russell 3,000 to be exact). These stocks all have more than 26% of their float sold short.
