South Korea: KOSPI Extends Sell-Off on Earnings Disappointment & Leveraged Unwinding
The South Korean stock market experienced continued turbulence on Wednesday. The benchmark KOSPI index closed down 5.98% (-360.42 points) at 5,663.24, after dropping as much as 12.6% intraday to touch 5,280 levels. The tech-heavy KOSDAQ fell 7.64% to 651.90. Intraday declines past 8% activated a Level 1 marketwide Circuit Breaker halt for 20 minutes.
The rout was driven by a sell-on-news reaction to semiconductor earnings. Despite SK Hynix reporting quarterly profits, shares fell 8.8% as results failed to exceed elevated market capex expectations. Samsung Electronics dropped 6.2%. Additional selling pressure stemmed from retail margin calls and regulatory deposit tightening on leveraged products.

Taiwan’s Taiex index sank 3.76% (losing 1,564.18 points) to 40,039.18, heavily dragged down by a 4.1% fall in TSMC amid global chip capital spending uncertainty. Japan’s Nikkei 225 fell 1.49% to 61,434.19 as Tokyo Electron and tech exporters recorded modest declines.
In contrast, Hong Kong’s Hang Seng Index rallied 1.96% (+496.11 points) to finish at 25,807.92. Gains in Chinese state-backed enterprise shares and internet platforms buffered the benchmark, supported by domestic fund inflows.
