South Korea: KOSPI Surges on Tech Optimism; KOSDAQ Slides
The South Korean KOSPI index climbed 5.42% to close at 8,930.30, marking its largest single-day percentage gain of the year. According to local financial reports, the rally was powered by semiconductor heavyweights Samsung Electronics and SK hynix. Robust earnings guidance from Micron Technology and positive supply outlooks from Qualcomm overnight relieved market fears of cooling demand for AI server hardware, prompting foreign institutional investors to aggressively buy large-cap Korean chipmakers.
In contrast, the junior KOSDAQ index diverged from the main board, falling 2.36% to close at 887.81. The decline was attributed to institutional capital rotation, as funds were reassigned from KOSDAQ-listed secondary battery component and biotechnology companies to acquire KOSPI-listed semiconductor names.
Japan and Taiwan: Nikkei Surges Above 72,000 on AI Demand
In Tokyo, Japan’s benchmark Nikkei 225 surged 4.89% to close at 72,366.34, recovering all losses from the previous session. Reports from Nikkei Asia indicated that buying was concentrated in semiconductor fabrication equipment suppliers Tokyo Electron and Advantest. Upbeat forecasts from US technology firms encouraged investors that capital expenditure in AI hardware remains robust. Lower regional fuel imports from declining crude oil prices also provided support for utilities and heavy industrial manufacturers.
Taiwan’s Taiex index climbed 0.70% to close at 46,367.00. The gain was led by contract chipmaker TSMC, which rose on optimism regarding advanced packaging capacity bookings for major global graphic processing unit (GPU) developers.
China and Hong Kong: CSI 300 Rallies While Hong Kong Slides
Mainland Chinese equity markets finished the session with gains. The Shanghai Composite index rose 0.59% to 4,120.28, and the blue-chip CSI 300 rallied 2.20% to close at 5,009.59. Buying from domestic state-affiliated institutions provided support for major industrial sectors. However, Hong Kong’s Hang Seng index fell 1.23% to 23,076.91, weighed down by energy conglomerates due to lower crude prices and profit-taking in financial listings.
Australia: Resources Drag Pulls ASX 200 Lower
Australia’s benchmark S&P/ASX 200 index declined 0.68% to close at 8,748.70. According to local financial analysts, gains in utility and financial sectors were offset by declines in resource companies. Falling global crude oil and gold prices led to selling in mining and energy stocks, capping index performance.
