There's no possible way that the O/S is only 5M. Like has been said, the last filing shows over 11 billion and the split was only 1-100.
That being said, I agree that the price moved alot on few shares being traded. I was in and out of it twice today after I saw the big moves it started making in the AM. Was a pain that I had to call e*trade to make the sells but they let me buy online no problem.
FDA approval talk is meaningless, it's not their product that was submitted, they're only selling it, and I use that term lightly because they haven't had much success selling other FDA approved products they rep.
As long as it's only looked at as a trade today was good and tomorrow could be as well, depending if people (mostly NIR) are able to dump. If not it could be another day like today.
Trade it people, don't invest in it!!
