I mean, isn’t a company’s valuation decided by the company themselves? Rest, when market forces are controlled by private hedge funds, asset management companies, and retirement funds, I feel normal Market rationality cannot be assumed. Market ownership right now is highly concentrated in these entities, and they have all the incentives to keep these valuation up for the reasons you stated.

It’s interesting that the more you learn about the market the more it looks like a ponzi scheme😂
