The 145 million shares of Blackberry that were short sold are being rapidly covered over the past few trading days. The worst news they could have is that the company is interested in going private or being bought out, and this is primarily the reason why the stock is experiencing the price spike.
This is a little depressing for people that were looking to go long and have no position as this completely takes the company out of the radar now. When you’ve dumped many hours of research into something and see it go to waste like there, there is a little resentment, but now the research radar will get taken to other directions.
