I would not want to be short before the earnings announcement. This is going to be very painful for all the shorts when earnings comes out. Hopefully you have purchased shares from the weak hands. This puppy is going to return handsomely after earnings!
Although I am long I am afraid that they may blow it again since the new CEO could use the former management as an excuse to put all possible bad numbers in the last quarter. What really will matter is guidance about the company's future and Icahn's intentions.
