Samsung Electronics Co LtdSamsung Electronics plunged over 10% on concerns the AI boom has become overextended, indicating weakening end-customer demand for its chips.
U.S. stocks settled lower on Monday as a sell-off in South Korean chipmakers weighed on technology shares and crude oil prices surged amid renewed U.S.-Iran hostilities. The S&P 500 fell 0.79%, the Dow Jones Industrial Average lost 0.26%, and the Nasdaq 100 dropped 1.88%. South Korea's Kospi Index tumbled more than 8% after SK Hynix and Samsung Electronics plunged over 10% on concerns the artificial intelligence boom has become overextended. WTI crude oil soared more than 9% to a three-and-a-half-week high after the U.S. launched fresh missile attacks against Iran over the weekend, and Iran retaliated with strikes on targets in Jordan, Bahrain, Kuwait, and Qatar while also attacking two vessels near the Strait of Hormuz. President Trump later said the U.S. is reinstating the Iranian blockade and stopping Iranian ships from using the strait, demanding a 20% fee on all cargo for U.S. protection. Fed Governor Christopher Waller added to the pressure by saying the FOMC may need to tighten monetary policy if core inflation remains elevated. Software stocks rallied, with Atlassian up more than 8% and Intuit up over 5%, while energy producers gained as Phillips 66 and Valero Energy rose more than 5%.
