I get the sense most of the buying has been from short covering. Shorts decreased from 27M to 25M as of dec 15. With prices creeping up slowing and technicals starting to finally work(still angry that it broke down last time - but i did add to my position), I get the feeling a slow short squeeze is coming. Surely enough, they're getting closer and closer to breakeven. A profit lost is always a bad thing.
Where did you get the Jan 15th short interest of 17 million shares you quoted? I always look on yahoo but yahoo doesn't have the number you specify. It still has the December 31st data of 25M short. I was hoping the stock would preserve that short interest rally fuel for a run in a higher range.
