I don't think this is true. Tech stocks are flying because they had great quarters and are poised to thrive in a post covid environment. Similar for home improvement. Similar for big box stores that were able to accommodate shoppers. Meanwhile airlines and cruises are 50% off their pre covid levels. Banks are still way off their highs(this despite strong quarters for many). Reit's are rightfully in the tank.market has no relationship to earnings or the economy just turbo boost by low interest rates and government buying corporate bonds.
It's true the tech stocks are on turbo boost, I think the market is def top heavy, and yesterday was only a small step towards equilibrium, but it is not like there are high flying stocks of companies that are currently tanking.
