re: Someone explain this Game Stop deal.

When you bet that a stock will go down, you can lose a lot more than your investment if it goes up. And even more if you've borrowed money to bet on it.

Hedge funds and investment banks have played this game for years and the game is up. They are now getting destroyed by the internet, who is buying the stock to make it go up and sending some of these Wall Street firms hurtling toward bankruptcy.

Of course a lot of Wall Street is getting in on it right now but the ones that bet wrong are getting punished for taking too much risk.
