Market capitalization is key. Tesla is 15 times bigger than Ford. And growing.Yes the most valuable automaker "in stock market capitalization", however with no basis for it that is based on profits, earnings per share, or market share. And that is just a complete disconnect from reality. They recently passed Buick by a nose, but of course they are not even an automaker just a dwindling marque of GM.
Elon Musk could snap his fingers and buy Ford.
That's power; that's the strength of Market Cap.
