It's pretty crazy that a few (well a lot I guess) crazy tweets can crater a companies share price.
Tesla has been an obvious bubble for the last couple of years. Musk got the shares up to a ~123 P/E level which is about 10 to 25 times what other car companies are valued at. The rest of Tesla is a battery company and those just aren't that valuable. The solar roofs and home batteries have been no-shows for the most part (delayed massively--if you can get them at all). About the only profit Tesla makes is from other car manufacturers paying Tesla for carbon credits.
I could even go as far as to say it was a borderline pump-and-dump scam. Musk got his massive stock option payout only if the stock market valued Tesla highly. So, there was a massive campaign to do everything to bring profits forward, to do everything to hype up the stock, to gain a cult-like following that will buy TSLA stocks, etc. until Musk got his massive stock options. His biggest success was forcing Tesla into the S&P500 so many people with mutual funds that follow the S&P500 had to buy TSLA near all-time highs. After that point, he has been selling many, many shares as he dumps it for profit.
Yes, crazy tweets have an impact. But, the real impact is that Tesla isn't as profitable as it needs to be for its valuation. This is really harmed by the fact that there is a huge drop in demand for Tesla vehicles right now. The non-stop talk of recession that isn't here has really impacted their target buyers (mostly the wealthier right-wing news viewers). Their used prices have plunged, so people can just buy used. Tesla had to drastically cut prices and cut production. That will drop their profits even further. As Musk continues to dump his shares, expect a lot of pain for TSLA in the short term.
