Kospi jumps 4% as Samsung, SK Hynix lead chip rebound despite Ken Griffin's AI bubble warning

invezz.com (Swedish) —

South Korea's Kospi index rose over 4% on Wednesday to 5,772 points, recovering from a weekly low of 5,465, as memory chip stocks rebounded in line with US market gains. Samsung Electronics jumped 7.3%, while SK Hynix and SK Square rose 8% and 7% respectively, mirroring strength in US AI and memory companies like Dell and Nvidia. The rally followed falling Treasury yields and oil prices amid hopes for a US-Iran deal. Billionaire Ken Griffin warned the AI industry is "certainly in a bubble," echoing concerns from Ray Dalio. The Kospi remains below its 50-day moving average, with technical indicators suggesting a possible decline toward 5,272 support.
