U.S. Indexes Extend Gains as Tech Rally Lifts Sentiment

Major U.S. benchmarks, including the Dow Jones, S&P 500, and Nasdaq, advanced on renewed investor optimism following upbeat Big Tech earnings. Amazon surged over 13% after its cloud unit reported 20% year-over-year revenue growth in Q3, its strongest since 2022. Traders pointed to improving risk appetite as market breadth expanded across sectors. Analysts said steady macro data and lower volatility indices support the case for a year-end rally. Momentum in artificial intelligence-linked shares continued to underpin the Nasdaq’s monthly performance, now tracking its best October in four years.
