idk, I read an analysis recently that retail investors in funds like the S&P500 are breaking how the stock market is "supposed" to work since people keep pumping the same money every month for retirement into the same 500 companies (or whatever an index is funding) without consequence to their actions, so they're never punished. Line goes up. The purchasing power of the masses outweighs the old brokerage class that decided which companies succeeded based on "real merits".

Probably very true, very simplified.

The best strategy then would be to know when the retirement fund money stops doing this due to age pyramid collapse i would assume.

Agreed but there is definitely sector rotation still that all the banks / insiders can play for an extra few points
