South Korea: Historic 6.23% Rebound Triggers Buy Sidecars
South Korea’s financial markets staged one of their most explosive recoveries on record today. The benchmark KOSPI index soared 6.23%—or 427.58 points—to close at 7,284.41 (Washington Post). The junior KOSDAQ index surged 5.80% to close at 829.43 points (Seoul Economic Daily). The massive buy orders triggered automated program trading halts (buy-side sidecars) to manage regional order flows.
The rally was led by semiconductor heavyweights SK Hynix and Samsung Electronics. Technical bargain-hunting following the previous sessions’ heavy drops brought back foreign and domestic funds. Concerns about near-term hardware peak-out and chip oversupply were temporarily set aside as the cooler U.S. inflation data eased pressure on interest rate assumptions. In response, local circuit breakers remained quiet, and the USD/KRW exchange rate closed lower at 1,484.70 Won, supporting domestic liquidity.
Japan & Taiwan: Semiconductor Stocks Lead Tech Rebounds
In Tokyo, the Nikkei 225 index rose 1.28% to finish at 68,613.89 points, continuing its recovery path (TradingKey). The broader TOPIX index increased 1.22% to close at 4,088.12 points. Gains were driven by chip-testing and equipment names, which tracked the global tech rebound. In Taipei, Taiwan’s TAIEX index leaped 2.00% to close at 45,631.59 points, led by TSMC as buyers returned ahead of its quarterly results (Focus Taiwan).
China & Hong Kong: Mainland Slips on GDP Cautions while Hang Seng Advances
Mainland Chinese stock indices closed lower as investors took profits ahead of upcoming macroeconomic indicators. The CSI 300 index fell 0.20% to close at 4,786.78 points, and the Shanghai Composite lost 0.29% to finish at 3,955.58 points (Trading Economics). In contrast, Hong Kong’s Hang Seng Index rose 1.48% to close at 24,701.10 points, benefiting from defensive capital rotations and improved risk appetite across regional markets (The Guardian).
