Tesla is a massively overvalued stock and has been for a long time. When they announced their recent dire sales, the share price actually rebounded because the clown Mush spouted his usual nonsense about the real value in the company - self drive and robo-taxis - but it’s been widely reported for some time that the companies tech is a dud because Musk decided to remove all the expensive components that actually make the technology work. They lost their first-move advantage; their competitors have caught up and surpassed them both on EVs and self-drive tech.
