Personally, I think the short position is so small as to be virtually unimportant. About 750,000 shares short on a float of 166 million shares - that's next to nothing. And that's an incredible portion of the small short interest that evaporated in the last two weeks of the year, perhaps some shorts were in the red and closed out to take the loss in 2014.
If we get some very good news and rally significantly, we'll likely see the short interest rise some, but can't believe it's going to be anywhere near significant in the foreseeable future.
