Andrew Left told Reuters that his firm Citron Research is still short shares of GameStop. Left shorted GameStop when it traded around $40 per share, and forecasted publicly that it would fall to $20, Svea Herbst-Bayliss of Reuters reports. “If I had never been involved in GameStop and came to this right now, would I still be short this stock? 100 percent. This is an old school, failing mall-based video retailer and investors can’t change the perception of that,” Left told Reuters. Shares of GameStop are up 47%, or $36.01, to $112.80 in afternoon trading. Left last week announced that he would stop publicly commenting on the company given threats to his family.
