Deep Tide TechFlow news flash: On July 22, over the past month, the S&P 500 has been repeatedly oscillating near record highs. However, the proportion of constituent stocks that hit 52-week new highs since March 30 has risen from about 35% to 46.1%. This suggests the index appears to be stagnating, while the internal advance range is still expanding. The market is not relying solely on a handful of large-cap tech stocks; capital is gradually spreading into more sectors and individual stocks. (Note: 46.1% does not mean all of them set new highs on the same day; it refers to the share of stocks that have cumulatively reached new highs since the end of March.) (Jinshi)
