Business and finance news from the Asia-Pacific.

Technology shares fell, snapping this week's rally, after disappointing earnings from two industry heavyweights revived concerns about the billions of dollars companies are pouring into artificial intelligence. Samsung Electronics Co. shares dropped more than 5% after profit missed estimates, dragging down the Kospi Index — a bellwether for the AI trade — by 2.9%. That marked a sharp reversal from Wednesday, when the gauge posted its biggest rally since July as strong earnings from chipmaker SK Hynix Inc. fueled gains across technology stocks. Alphabet Inc. slumped 10% in extended trading after sales underwhelmed, reinforcing investors' fears that Google is losing ground to AI rivals despite pouring hundreds of billions of dollars into the technology. Futures for the Nasdaq 100 Index slid 1.3%, after the underlying benchmark climbed for the past three days. The broader MSCI Inc.'s Asia Pacific equities reversed earlier gains to drop 0.7%. The news wasn't all bad as Microsoft Corp. shares rose 2.9% in after-hours trading on solid cloud sales, while Oracle Corp. earlier surged 11% after issuing a long-term outlook for free cash flow. A gauge of Oracle's credit risk improved the most in nearly nine months.

And - Federal Reserve Chairman Kevin Warsh on Wednesday left the central bank on track to raise interest rates again this year, even as he stuck to his refusal to offer any explicit guidance on the future path of policy. Operating within his self-imposed communication boundaries, Warsh used his assessment of a strong economy and warnings over persistent inflation to signal the Fed's job is not yet done. The message reinforced expectations that officials will raise borrowing costs in December — after holding them steady Wednesday — with the potential for another increase in early 2027. Still, Warsh was careful to leave his options open. Bloomberg's Yvonne Man and David Ingles spoke to Larry Hatheway, Head of Research and Global investment Strategist at the Franklin Templeton.
