I think the difficulty for valuing Tesla was it's profitability. The bulls always believed that Tesla would be profitable and hence the valuation was way too low for a company with CAGR 50%. The switch over to profitability caused a rush of institutionals.Tesla is a pretty sure thing but I'm not sure about the time lines as we have seen, wall street doesn't give Tesla the correct valuation until they are like 150% sure Tesla is going to succeed in what they say, hence depressed stock price for 5 years and then x10 in 18 months.
It's probably quite rare that a high growth 20-30B revenue company is unprofitable for as long as Tesla has been.
