You’re trying to value a company without looking at debt, so you’re missing the big picture.
Total Debt:
VW. $237B
GM. $192B
Toyota. $190B
Ford. $155B
Daimler.$108B
Nissan. $42B
BMW. $80B
Honda. $42B
So your market cap analysis missed ~$1 trillion of enterprise value in your comparison set.Simply put, the stock market cap is the total company value minus the debt.
Tesla debt by comparison is $14 billion.
All those companies together being worth only about 3x Tesla is perhaps surprising, but the market is weighting for the possibility that their entire current product lines will be virtually unsellable if not illegal to sell in a decade or so.
