Tesla is also able to have almost positive cash flow on high margin high demand cars in the middle of a pandemic. The other automakers are leaking money like there is no tomorrow.
Ford, GM, FCA have a thin wedge of the market that is still profitable for them and that market is under attack, with little indication of them being able to make a huge splash in another market. Not to mention a broader shift in car market and transportation that requires massive investment.
If you don't grow, don't make much profit and are risky, meaning a couple of bad quarters almost kill you your stock is not gone be worth much.
Telsa is not going to go bankrupt in the near- or medium-term. There's just too damn much money backing them.
