Do you really expect a 100+ year old company that sells 3 million vehicles annually to be growing 125% annually? Where would the cars go?
Valuation is NOT a representation of the future of even expected future of a company.
I could bet on Tesla and help its value rise just because I think tomorrow other people will bet on them and so the share will rise. I could bet on Tesla because I think Softbank has way too much money and will ensure I get an nice ROI soon. I could bet on Tesla because I just see that they've been growing and think it will keep going at the same pace without issue.
As long as you have people ready to buy at a higher price for whatever reason, the share will rise. And if people stop believing it will drop. Both regardless of the actual metrics behind. When Tesla gains or lose more than 10% IN A DAY, it's not because suddenly their metrics are 10% better or worse, it's just the mirror of the market's collective psychology.
Looks like they just posted a solid ~5% YoY growth for the last quarter, while TSLA posted ~125%. It's clearly an interesting difference. Valuation is the metric that summarizes all of the other metrics.
