It seems like a smart decision once you look at car companies' market caps: Tesla: $651 B Toyota: $288 B Volkswagen: $152 B Daimler / Mercedes: $99 B Ford: $60 B
People said this 3 years ago too, arguing Tesla was too big. guess what: it got way bigger. Tesla is forcing other brands to have to adapt or die. They are way behind Tesla in technology, infrastructure, and marketshare for electric vehicle and battery tech.
And it will continue to go up until it doesn't. Maybe Tesla has a vault of unicorn blood and is just waiting for the perfect time to unveil it, but as a car company, their stock valuation makes absolutely no sense. It would take a miracle for Tesla to overtake more than all 3 top automakers combined. There is zero indication this has any possibility of becoming a reality.
Tesla's stock performance is in pure FOMO land now.
