IMO, I wouldn,t doubt it may had something to do with a last ditch effort to clean up a short position. It may have been set up if there was seen a stop loss down there around .40 and someone needed to cover, they may have seized the opportunity. The Fact that most of the order was sold as cross trades, suggests that whoever did it, didn,t want to lose the shares he used to knock the price down. The new short numbers will most likely tell if this was the case, as if it were a shorter, they would sooner make money by buying lower than having to buy higher. I believe there was around 30k shorts on the last report for Feb 15 th.
It could have also been someone that could see that stop loss and triggered it because they wanted those shares, then took the sp right back up. We know there have been many games played with our sp over the years, this is most likely just one more of those things.
IMO
