Agreed - Tesla has been an insanely good investment. I'm not sure about the next 10 years, but people have continuously underestimated them (and Elon Musk). The Norwegian so called Oil Fund owns more than 1% of Tesla.
has it been an insanely good investment because of changes to profit and loss, or because of other factors? (of course, building a car company of the scale they have is impressive. But by looking at tesla's financials vs stock price, youd conclude basically any other car company ever was a great buy by any reasonable metric)
Tesla is not and never has been a good investment.
Its a gamble.
The current evaluation of Tesla is still higher than real car companies + robot companies + robot taxi companies.
