I am interested in buying in (again) because of the excellent progress being made by this company. The shorts may or may not cover -- I got spanked on a company because of shorts, and adding the .OB does nothing to the really aggressive hedgies. There are plenty of .OBs and large caps being shorted as we speak.
IMVHO, a lot of money can be made if you jump in while the squeeze is on. But buying a shorted stock in hopes the crooks will one day cover is pure financial suicide.
In short (pun intended): Buy IGTN for the company and the management.
