If the case they will want to push this, IMO... 3.3b shares traded, someone is going to want to make money here, jmo... I think a push will come,, 3.3b volume I think we see movement, I know nothing about this ticker but the shear volume makes me believe this will have a move.
I own a few shares of this too. Purchased a couple years ago. I don't know that it's possible to short a subpenny. My theory is that someone holding a lot of shares, possibly purchased after the tango deal announcement, decided to take matters into their own hands. Perhaps someone who was feeling burned when the deal was unwound. It's just a theory.
