Good question and why i believe short interest has increased the past few quarters. As long as the growth is there, the stock will continue to perform. They have been executing so well that it is hard to imagine a miss anytime soon. The economy is still on very unsteady ground, and things could change quickly. Market downturn would certainly take the stock with it, but this company is not priced to perfection, but getting closer. That is where the shorts I think are correct. DTV will be putting so much cash to the bottom line for years to come. Reorganizing will be a plus this month, and of course possible buyout always looms.
good luck to all
