On Wednesday, GameStop (GME) stock recorded its largest ever one day share haul, surging by a massive 57% in the session. This was followed by today's 20%-plus jump. There appears to be some disagreement on Wall Street as to the cause behind the monster moves. As the stock has recently had extremely high short interest, some have put it down to a short squeeze. While Ihor Dusaniwsky, of predictive analytics company S3 Partners, believes the short covering was partly behind the buying spree, he doesn’t see it as the main reason for the surge. Rather, the reason lies elsewhere.
