It absolutely is.
With the rise of ETFs and 401ks people are incentivized (literally) by the US Gov to put their money in the S&P500
And the "instead of picking a needle in the haystack, just buy the whole haystack" only works if there is actual stock picking going on and you get to ride that, but now when there's so much passive investing, it's just everybody buying the haystack, even if there is no needle
Like with the ETFs and 401ks, they will happily buy as much NVDA at its ATHs, it's quite literally massive liquidity feeding orders all the time, coming from retail's monthly paychecks
