Quantitative analysts at JPMorgan, as reported by Bloomberg (BBG), have warned of a concentration in the U.S. stock market that echoes the dot-com bubble era. The market capitalization of the 10 biggest stocks is nearing levels seen during the dot-com era, with the S&P 500 rally drawing comparisons to that period. The weight of the 10 largest stocks in the S&P 500 ($SPX) now constitutes 33.1% of the total index, the highest in almost five decades. This Big Tech dominance in the stock market is raising concerns among analysts and market watchers, who see similarities to the conditions before the early-2000s market crash.
