Miami Fort Lauderdale, FL, October 15, 2026 —
U.S. stock indexes advanced on Thursday, as the S&P 500 and Nasdaq closed higher. Strong corporate profit reports from Marsh & McLennan and Kimberly-Clark helped drive the gains, according to the available account of the market’s performance.
The advance came alongside significant volatility in artificial intelligence stocks. Those shares swung as concerns emerged about whether the sector’s recent boom could be sustained. The reported movement left the broader indexes higher for the day even as AI stocks experienced sharp fluctuations.
The summary does not provide the indexes’ point or percentage changes, the specific profit figures reported by either company, or details about the timing and scale of the AI-stock swings. It also does not identify which individual AI companies were involved or specify the source of concerns about the boom’s durability.
As a result, the available information establishes the day’s broad direction and identifies two factors associated with it: strong profit reports from Marsh & McLennan and Kimberly-Clark, and volatility in AI shares amid sustainability concerns. It does not provide enough detail to compare the companies’ results, quantify the effect of those reports on the indexes, or assess how the day’s trading fit into a longer-term market trend.
The reported close was higher for both the S&P 500 and Nasdaq. No additional index performance figures or subsequent market developments were provided.
