Sometimes the market is slow to react when a down on its luck company actually turns things around. Ultra Petroleum (NASDAQ:UPL) has had a pretty impressive run so far this year, but it was on that list of highly shorted stocks just a few months ago. Quicksilver Resources (OTC:KWKAQ) and Goodrich Petroleum (OTC:GDPM)have also made lots of Wall Street enemies, and today their short positions are two of the highest in the space.

Looking deeper into Quicksilver, it's pretty easy to see why. The company has a highly levered balance sheet and its EBITDA can't even cover its interest payments. To find out what else doesn't look good for Quicksilver, and whether Goodrich should be on this list, tune into the video below.
