Short = Pinjam share from broker, sell now at current price, buy back later. Cheaper price = gain, price up = loss.

Basically, they manipulated and short the stock from 20+ down to 3. They got overconfident and doubled down. If the stock goes to zero, all their gains basically have zero cost. All at the expense of gamestop and their investors.

They got found out and the rest is blablablablabla go find and read or youtube if malas.

they are allowed to short 140% of the floating shares available, imagine theres 1 million shares, but they are selling 1.4 million shares into the market, where the additional 400k shares come from? magic lo

and because suddenly got so many shares selling flooding the market, it will bring down the price of the share by alot
