S&P 500 Earnings Boom Rests on a Handful of AI-Linked Stocks

what happened

According to FactSet, analysts expect S&P 500 companies to report a 30% year-on-year jump in third-quarter earnings. An analysis by Dow Jones Market Data, cited by the Wall Street Journal, shows that Nvidia and Micron account for 34% of that growth, while roughly ten companies, including Broadcom and Meta Platforms, deliver about two-thirds of it.

Analysts warn that the risk is that AI infrastructure spending may never pay off. Chris Grisanti, chief market strategist at MAI Capital Management, said the rest of the index is still expected to grow profits by 10%, which he called a respectable showing.

Larry Adam, chief investment officer at Raymond James, argued that comparisons with the dot-com bubble miss a key point, because today's AI leaders are already earning large profits.

why it matters

The concentration of earnings growth makes the index vulnerable: if confidence in AI spending weakens, chip stocks and the broader market could both suffer. Share prices, however, have risen far less than earnings, which some strategists see as a sign that valuations are less stretched.
