NEW YORK — Wall Street closed higher on Tuesday as a sharp rebound in semiconductor stocks lifted major U.S. equity indexes, with technology shares leading gains ahead of a busy week of corporate earnings reports.
The Dow Jones Industrial Average rose 385.38 points, or 0.74%, to finish at 52,224.64, while the S&P 500 gained 65.92 points, or 0.89%, to close at 7,509.20. The Nasdaq Composite advanced 329.13 points, or 1.29%, to end at 25,837.21, according to market data.
Semiconductor shares were the main driver of the advance. The Philadelphia Semiconductor Index climbed more than 5%, extending a recovery after recent declines had pushed the index more than 20% below its late-June record high, according to market reports.
Chipmakers including memory and artificial intelligence-related companies led the sector rebound as investors positioned for upcoming technology earnings reports. Micron Technology was among the strongest performers, while Intel and other semiconductor-related companies also posted gains.
Investors were focused on whether upcoming earnings from major technology companies would provide further evidence that spending on artificial intelligence infrastructure is translating into stronger business results. Companies scheduled to report results during the week include several large technology firms, keeping attention on the outlook for the sector.
The gains came despite continued market concerns over geopolitical developments and trade policy. Investors also monitored higher oil prices linked to tensions in the Middle East and ongoing tariff disputes, but those factors did not prevent technology shares from pushing broader indexes higher.
The technology sector was among the strongest-performing areas of the S&P 500, with semiconductor stocks helping reverse recent weakness in artificial intelligence-linked equities. Market participants said the rebound reflected renewed buying interest ahead of earnings announcements, while analysts continued to watch whether corporate results would support current valuations.
The market’s next major focus will be upcoming earnings releases from large technology companies, which investors are expected to assess for signals on artificial intelligence demand, corporate spending plans and broader economic conditions.
