This is a copy a copy and paste from reddit to help explain what's happening.
1) GameStop is a mall retailer 2) General trend is they go under (like Sears) 3) People by default pigeonhole them with Sears and sentiment drops 4) Covid hits and company suffers 5) Wall Street vultures want to kill it off and start shorting it 6) Stock at $4 and they continue with no regard to actual value... Let alone bankrupting a firm that employs 50.000 7) Some people (Michael Burry) start running the actual numbers and see there is some value, they start investing (mid 2019) 8) Few regular joes notice the same thing and find out shorts will continue to mess with stock and push it down no matter how it is performing. They short it 139%... Sold more shares than there are. 9) For shorts to cover, they need to buy back the shares. They pay interest on the shares they bought to immediately sell short. If they start buying back the price goes up. 10) people start buying stock and not letting it be shorted, it drives price a bit up. Hedge funds shorting the company are losing money if they cover so they double down trying to bring the price lower. Mainstream media is giving huge publicity to GME 11) people continue to buy and hold... Hedge losing money so they start selling options at a crazy premium thinking they will shake us off and collect, after stock dives due to their manipulation (Monday was a great example) 12) other funds on wall street smell blood and want in. Short hedge funds caught themselves in their own trap. First the gamma squeeze then the short squeeze z (margin call) 12) they lose 3bn so they get bailed out by their rich friends as not to get margin called. - until here they could have saved themselves if they flipped- 13) they return the next day and try to repeat. - instead, it backfires and stock keeps shooting up. They are on their knees at market close, about to get margin called ($175 per share) 14) Elon tweets afterhours and it punches up the stock even higher by other wallstreet funds (like BlackRoc)/($220) probably about to wipe that fund and finish some careers.
WSB doesn't have the purchasing power to do this. We simply made it public and piggybackef off of something bound to happen like a sunrise coming from the east
