Elon found out how to juice his own stock years ago. If you understand how options work, see above now 5 year old post. It never made any sense that TSLA was more valuable than it's next 10 competitors combined.
In a very basic sense, he (allegedly) buys a bunch of contracts saying he will buy at a higher price, which makes the market maker have to buy stock to hedge, then he dumps some kind of news to get the stock pumping and make the MM buy more stock, and drive price up. I'm sure he's doing it through 50 shell companies so it doesn't get back to him, but as someone who does trade and has watched this stock the last 5 years, run completely afoul of logic, it makes complete sense. He also fills wsb with bots and shills to pump up TSLA and more importantly, buy OTM calls.
