Tesla is trading at a 50x PE (2022 consensus) and plans to grow 50%+ in 2023, 2024.
I don't think that you can expect the stock to be where it is today in 2024 if the PE actually goes down to 12. You'll need to buy it now to lock in that PE of your purchase price.
It is trailing 170 P/E, obviously trailing earnings are not so useful for high growth companies but question is Tesla really a high growth company any more?
The consensus is that Tesla is not priced just for cars, it is priced on some other "intangibles".
Elon has said that Tesla's advantage will be manufacturing. If he is right and the global demand for EVs continues to accelerate, TSLA's PE will be below 6 at current prices before it is no longer growing 20%+ a year.
