US markets today: Wall Street jumps after softer inflation update; Micron sparks AI rebound

US stock markets rallied on Thursday after a better-than-expected inflation update eased concerns over the interest rate outlook, while a strong earnings report from Micron Technology helped arrest the recent slide in artificial intelligence-linked stocks, AP reported.The S&P 500 rose about 1%, snapping a four-session losing streak. The Dow Jones Industrial Average climbed over 350 points, while the Nasdaq Composite gained around 1.4%, led by technology and semiconductor shares.Investor sentiment improved after data showed US inflation slowed to 2.7% last month, coming in below economists’ expectations. While inflation remains above the Federal Reserve’s 2% target, the softer reading raised hopes that the central bank could continue cutting interest rates next year to support a slowing job market.Some caution persisted with market participants noting that recent economic data have been volatile following the US government shutdown, and that upcoming inflation reports may provide a clearer signal.Technology stocks got a further boost from Micron Technology, which surged nearly 16% after posting stronger-than-expected quarterly profit and revenue and issuing an upbeat outlook. Chief executive Sanjay Mehrotra said demand linked to artificial intelligence accelerated across Micron’s businesses, reinforcing its role as a key “AI enabler”.The results helped ease worries that heavy spending on AI by major companies may not yield sufficient returns. Shares of Broadcom and Oracle, which had fallen sharply in recent sessions despite solid earnings, rebounded, while Nvidia also edged higher.Elsewhere, Trump Media & Technology Group jumped sharply after announcing an all-stock merger with nuclear technology firm TAE Technologies, marking its entry into the nuclear power space. Cintas also advanced after reporting strong earnings and announcing a share buyback programme.Global markets were mixed. European stocks posted modest gains after the Bank of England cut interest rates and the European Central Bank held policy steady, while Asian markets ended unevenly.In the bond market, US Treasury yields declined, with the 10-year yield falling to around 4.11%, reflecting optimism following the inflation data.
