Yes, and those 4M are fails-to-deliver cases...others are invisidle cleared cases/settled transactions... Funds are quite nice fellows aren't they;O) They just know everything about stock manipulation.
I say we may be talking about 12x 4M = even 48M+ shorted stocks
That is quite a lot isn't that?
Naked shorting stays invisible from SEC because are all what SEC keeps track.
The shorts got nothing to worry, they get their shares from the warrants and can deliver and cover the shares they shorted at higher price. And then they laugh all the way to the bank.
