yeah it's odd trading. But one thing is for certain, somebody wants this thing to go down and that's where it's going. It will bounce back up though, sooner or later, this is at least a double.
The odd amounts of shares may be due to automatic buying. When I purchased 150k shares, it took 3 transactions in various amounts, all at the same price. I think this is caused by small variations in price and how long of a window the pps stay at the clients bid price. Just MHO & experience with my purchase.
