I don't think the car is very good, although besides my affluent sister I don't know anyone who owns one. The stock is overpriced and while it has had a run, it can and has moved double digits down in the process. Like 25% in a week. I recall owning it once, buying at the close the day before earnings, selling at the open for a 10% gain, and the stock was down 8% at the close. What's the PE?: 1500:1? Could it go higher? sure. so can bitcoin. It can also turn on a dime at any time and go down 50% or more in a heartbeat and dozens of analysts will claim they predicted it.
There are other companies, and there will have to be other companies, to supply electric vehicles.....XH, RIDE, to name a few....which are both down today, and charging stations (BLNK, SBE (SPAC for electrify america or some such)), and battery components (ALB, LIT) if the world converts to this technology. But at $800/share, I'm ready to delete TSLA and their cramped, heavy cars, from my watch list.
