Many think it's overvalued by around 50-500x what the company is worth. From what I've seen they're very good at cash management and continually invest in company facilities, very similar to what Bezos was doing pre-AWS with Amazon's tight margins.
Even the loudest, most annoying haters don't think it's overvalued by 50x. More like 10x at most, if you think it's just like any other car company and growth is going to zero.
My point was about the business though, not the stock price. The business is solidly profitable.
