If there was a way to gain more than the S&P then in theory the market would find that gain and reduce it to being the same as S&P. If investing in all stocks would be better then Vanguard all stocks index would be better.

Hedge funds and managed funds for “serious investors” try to get better than the S&P and some succeed but most fall below. Is general not everyone is doing it but by the way things are now everyone really should. It’s a surefire way to get 4% + inflation.
