shortsTough call as to when a short feels forced to cover. It could be someone shorting the stock who expects to buy back in at a lower price and is covering with warrents, This is the kind of shenanigins a broker or a pro will pull. Someone in this position can ride the short out until the warrent closing date.
Out of my league but I understand why it is done and have come close to pulling the stunt myself. That is why I have a non shorting account- I do not want to get too smart for my own good.
