Kospi Surges 18% in Record AI-Fuelled Rebound

The Kospi index in Seoul jumped almost 18% on Friday, marking its biggest one-day percentage gain on record, as chipmaking stocks staged a dramatic recovery.

The surge was led by Samsung Electronics and SK Hynix, which each surged over 20% after reporting strong earnings that reassured investors about the AI boom's sustainability.

The rally followed a global tech rebound that also lifted U.S. and European markets.

The volatile session underscored the market's sensitivity to AI-driven growth narratives.
