Elon is doing what he had been doing to his own company tesla's stock.
Tweeting out "Price to high?" then their investors panicked and the stock dumped price the very next day.
It is like he's playing a childish game where real money is involved. Yet what does he care, he has trillions more where that came from.
Not so surprised because what do you really expect from a guy who named one of his companies The Boring Company.
