I don't understand all the complexities but apparently some large hedge funds tried short Gamestop and retail investors have sent the price up causing a massive short squeeze. The price went from about $20 a share on January 12 to the close today on January 27 at $340. Absolutely insane. The previous all time high prior to January 12 was around $62 back in 2007.
