I think there is a fundamental difference now, the government has bailed out stocks twice in 2008 and 2020. Moved Heaven and Earth with the fed and indirect injections of capital to prevent the rich from losing money. So these stock prices reflect tax dollars billing them out in the downturn.
I had a similar sort of thought but figured it was an automated thing, where they would buy or sell to manipulate the market price with the fund removed from the owners of stock.
Something like that could have made a fortune as the stock price was gaining and as such been able to manipulate the shit out of the stock price and fuck short Sellers and everything.
