They don't have to take share.  The EV pie is growing.  They don't even need to keep their % of the EV pie, so to say.  As long as they grow at a high rate and have solid margins(profits) they should be worth a higher p/e.  How much higher is debatable and depends on many factors.  

I sure wish all the geniuses posting tslas going to shit now would've been posting when they were at $400....  its trending down in a down market.  No one knows where that will lead.

People have been saying it’s overpriced the entire time. 

What’s more interesting is looking at all the posts of people claiming it should go even higher and how it was somehow justified. 

Tesla is priced at a higher PE *still* than a lot of tech companies. Let alone what the PE was. 

Missed numbers and now firm brand decline evidence are probably just the beginning. It’s not just market trends working against it.
