U.S. stock indexes advanced during October 27 morning trading as large AI-related companies supported the market, AP reported. At 11 a.m. Eastern, the S&P 500 was up 0.5%, the Nasdaq composite 0.9% and the Dow 0.1%.

AP said most stocks in the S&P 500 were lower even as the index rose, reflecting the influence of some large companies. Investors were also awaiting major earnings and central-bank decisions. These intraday figures are not closing prices or an investment recommendation.
