On October 29, 2026, South Korea's benchmark KOSPI index witnessed a significant decline, dropping by 3% to reach 5,832 points. Samsung Electronics, a major player in the market, saw its shares plummet by over 5%, primarily due to its third-quarter chip profits falling short of market expectations. Meanwhile, SK Hynix, which had initially surged nearly 7% earlier in the session, eventually ended up in negative territory.
