> How much further do you think it really can fall?
Well that's a great question. If you think Tesla is close to bankruptcy than the answer is: all the way down.
But even so, downward pressure can create more downward pressure if Tesla has been over leveraged to obtain loans or to buy Twitter.
Let's say Tesla stock was used as collateral for loans, with a promise that the stock won't go below $100, e.g. If it does go below $100 then someone is on the hook to provide cash collateral to offset the loss of the value of the stock. The primary way to do that is to sell Tesla stock to raise cash. That creates further downward pressure on the stock price.
Or Tesla might be lying about something materially related to the stock price, which you've discovered and are pointing out to the WSJ, because you know, you have a reporter over there on speed dial (not everyone does, of course, but if your trades are $100M at a time then you should).
Or maybe you're betting that Elon is going to self implode and jump out of the window, or murdered because of shady dealings with Russia. Sure that's long odds maybe, but not entirely unheard of.
Derogatory information about a company or it's CEO might be a gamble that's worth taking. I'm sure there's a lot of dirt in Fortune 500 companies that is waiting to be found with the right team of private investigators.
