Korean Markets React to Nasdaq Plunge on AI Fears

Korean outlets report that the U.S. Nasdaq fell more than 2 percent on Thursday due to AI-related concerns following earnings from mega-cap companies like Tesla and Meta, with a recovery in oil prices adding to the pressure. This decline in U.S. markets triggered a sharp selloff in Seoul stocks, with the KOSPI plunging more than 5 percent on Nov. 5 amid fears of AI regulation and a Democratic sweep in Congress that could slow data center build-outs. The downturn has extended into Nov. 6, with the KOSPI crashing below 5,000 and semiconductor stocks, including Samsung Electronics and SK hynix, facing panic selling as investors worry that the AI investment cycle may be peaking.
