If memory serves, Elon sounded a similar "alarm" regarding Rivian's long-term prospects several months ago. It's true that Rivian is not without issues, and it's undeniable that the company will not be profitable for some years. The company does however have a substantial, legitimate order book, reasonably competent executive management, high-profile backers committed to the company's success and perhaps most importantly, good access to capital. It's long-term success is not a sure thing, but the prospects are more than decent. I'm not sure if if Lucid has similar assets and suspect it's long-term success is less certain than is Rivian's, but quit frankly, the company whose success seems to be heading to the "Questionable" category the fastest is Tesla.
It's tempting to chalk up this new remark regarding Lucid to Elon's self-serving, PT Barnum-like streak, but at this stage, his behavior has become so erratic and outlandish that it is now self-destructive. The precipitous drop in TSLA share price is due in large part to Elon; his increasingly outlandish behavior coupled with pronouncements that are more and more ridiculous are only part if the problem. His sale of large amounts of his own Tesla stock, the most recent contrary to a promise made after selling a large stake earlier in the year, is probably the bigger culprit in the recent precipitous TSLA share price decline. Elon has again promised not to sell more TSLA stock, but at this stage, his credibility is, shall we say, suspect. With Tesla sales for 2022 likely to be lackluster, and competition from other makers like the recently disparaged Lucid Motors increasing substantially, investors are unlikely to bid TSLA up, at least in the short term.
If Elon comes to his senses, and concentrates on improving Tesla quality rather than starting Twitter wars and trashing competitors, perhaps the stock price will stabilize or even increase. It's a decent bet that none of that will happen however, and shorting TSLA may now be the better strategy.
