U.S. Stock Market Concentration Hits 35-Year High, UBS Warns of Potential Consolidation

UBS has reported that the concentration in the U.S. stock market has reached its highest level in 35 years. According to NS3.AI, this development comes as the market-cap-weighted S&P 500 significantly outperformed the equal-weight index in the six weeks leading up to May 15. UBS has cautioned that the market may experience a temporary consolidation period as the earnings season concludes and focus shifts back to the Middle East.
