> Not sure what relevance Musk selling shares has to do with profit they've made. That seems completely irrelevant.
Selling shares for more than the company made in its entire existence, demonstrates the shares are overvalued.
> By comparison GM made 2.7 billion and Stellantis lost 20 billion.
2.7/3.7 = 0.73; GM's market cap is $77.67bn, using them as your framing of the problem gets you to a Tesla market cap of $106.40bn, not their actual ~$1.5T.
And Toyota made 40-45 billion USD profit for each of the last few years, i.e. more than Tesla in its lifetime, while having a market cap that's currently $316.8bn.
Telsa, market cap $1551bn, about 5x that of a company which makes more each year than it did in total, is overpriced. Especially given how harshly both Tesla's profits and sales are declining even in otherwise growing markets.
Telsa could shift the decimal point on its market cap one place and still be overpriced.
Given what they are as a business, they are not in "a phenomenal position financially", they are in an OK position for a normal boring traditional car company and a terrible one for a trillion-dollar market cap club company.
