This is true, Tesla as a car company would have been much better if Musk quit it at least 2 years ago.

Tesla as a stock, which is the primary product of the company, would crater immediately, by something like 90%. All of it's "future value" is derived from fantasies closely tied to Elon Musk "genius". If one value Tesla as a car company, it's worth something like 10$/share.

PS. Tesla head of board of directors, Robyn Denholm, sold almost 120M$ worth of shares in the last 3 months, something like >60% of her holdings.

first, folks need to exit/reduce their positions stealthily without disrupting the market. this takes time; for big positions it is not unusual to be exiting it for more than 6 months

I'm not sure suing ceos for bad choices is a thing. Has it ever been done successfully?
