So basically you guys are saying it is the markets going down, affecting almost everything (except oil). And had nothing to do with Elon Musk and Twitter. I agree with the former, but I think the latter is also having an effect. Tesla just got kicked out of the S&P ESG Index. That means a lot to larger institutional funds incl pension funds, etc.
TSLA still has a high PE, but that is nothing new. And if anything its long term growth prospects and profitably have increased lately. So it is not the company. But if you want to compare companies, you can't ignore this:
TSLA - book value = $29.22/share, PE= 90
GM - book value = 39.83, PE= 5.8
F- book value = 11.77, PE= 4.4
The diff is what the markets perceive in TSLA's future value and performance. Once growth companies become profitable, their stocks often drop some, until eventually the growth and profitability and value come to equilibrium. That's called maturity (PE 20-30 X earnings at high end) and what happened to once other growth companies like Facebook (now 13.7), Google (20.2), Intel (6.9), etc, etc. Where TSLA ends up, who knows. Elon Musk doesn't look like he intends to slow down with his ambitions.
