Julian Emanuel warns of S&P 500 risks due to high concentration in AI-focused stocks.
Julian Emanuel, a strategist at Evercore ISI, warned that the S&P 500 faces significant risks due to its heavy concentration in a few dominant stocks. Currently, 10 stocks account for a record 38% of the index, a level higher than the peak seen during the dot-com boom. This concentration is largely driven by the massive capital expenditures on artificial intelligence. Investors are becoming increasingly cautious as the market reacts to recent data. For example, shares of Alphabet fell 9% over the last five sessions following a capital expenditure report that slightly exceeded expectations. Analysts from Barclays have noted that enthusiasm for AI spending may be beginning to cool, especially as new Chinese models challenge the high costs of US tech companies. If the upcoming earnings reports from Microsoft, Meta, and Amazon show continued high spending without clear signs of slowing, the concentrated index may face a1 pressure. Investors may shift capital toward other sectors, such as healthcare and financials, if the market is not comfortable with the sustained high spending.
