Tesla is not just a car company. They are diversifying their income. Trucks, vans, are things they are planning to do but are holding back on because of a lack of battery to build those and because of continued spectacular demand for very lucrative high end cars.

And that's just vehicles. Their solar business is scaling nicely. Grid storage is a growth market as well. And of course they are pairing their solar with domestic storage as well. All rapid growth markets. That's why their market cap is what it is. Multiple rapid growth markets, a proven ability to scale and execute, etc. That's why investors love them.

A market crash would be brutal for everyone. Particularly those with struggling product lines and outdated products that are very dependent on both to secure the revenue to invest themselves out of that mess.
