US market indexes fell sharply after Samsung Electronics posted preliminary earnings that beat expectations but still disappointed investors, triggering a sell-off across the semiconductor sector. The Nasdaq Composite dropped 1.3%, the S&P 500 fell 0.6%, and the Dow Jones Industrial Average declined 0.4% by late morning. Samsung's revenue rose about 129% year-over-year and operating profit surged 19-fold, yet its stock fell 10% in Seoul as investors had priced in even stronger growth. The rout spread to US peers, with Micron Technology down 7.2%, Intel falling 10.6%, and Lam Research dropping 7.7%, weighing heavily on the tech-heavy Nasdaq. The Dow was also pressured by declines in Caterpillar and Honeywell International, which fell 5.8% and 8.5% respectively, partly on AI data center concerns and Caterpillar's acquisition of Skycatch.
