Index funds don't need a correction, Random Walk doesn't show index funds outperforming every individual pick, it shows indices beating active trading over time, esp with fees. Assuming relatively perfect markets, it's self adjusting. If there is a short term where active management beats passive, then the money adjusts until active fund is over priced when the index funds make better returns again.
