I'm not sure if "the market doesn't know how to price Tesla and is rapidly fluctuating up and down" is really saying much.

In terms of revenue Bosch is comparable to Nvidia and Tesla. IKEA is about half that and Schwarz is about Nvidia and Tesla combined, but of course those two are bad comparisons because they are in the rather unexciting retail market.

But generally I agree that exciting upstarts that reach fortune 500 size tend to be US companies.
