Earlier quoted context omitted.
It really is wild that investments are driven by the marginal investor, not the median investor. 99% of us can think that Tesla is trash, but 1% of world investors is an absolute ton of capital.
You're more complaining that investors who don't own a stock have no influence on its price. Which is true, but I don't see a workable way to change that. The median investor in Tesla, on the other hand, seems to be happy with the situation since they're not selling.
I agree that the median investor feels that way, I just think that the median Tesla investor (apart from passive broad based funds) is a tiny, tiny, tiny part of the market.
