Pumping up the stock value up to fuck over hedge funds that naked shorted gamestop’s stock. A naked short is where there isn’t enough stocks available to cover the short. Theoretically shorting a stock is illegal if you don’t cover the short to existing real stocks. In this case it’s wall street fuckery since the short contracts have more stocks than exist, so no way it’s possible the shorts are legal.
Reddit got together and started buying Gamestop’s stock to increase it’s value, this will fuck over anyone with a short contract big time.
