Asian stock markets have experienced periods of volatility and mixed performance. In late September, the Hang Seng Index opened sharply lower by 513 points, driven by heavy selling pressure in the technology and financial sectors. Major losses were recorded in prominent internet companies such as Alibaba, Tencent, and Meituan, alongside declines in banking stocks like HSBC and Standard Chartered. By mid-October, market trends showed more varied results across the region. While Japan’s Nikkei 225 declined, other markets saw gains. The South Korean Kospi rose by 1.8 percent, supported by the automotive sector, and Chinese indices like the CSI-300 and Shanghai Composite edged upward. The growth in Chinese markets followed economic data indicating that industrial production and retail sales exceeded expectations, with third-quarter GDP growing by 4.5 percent. On October 19 and 20, 2026, market movements remained divided. The South Korean KOSPI saw a strong recovery, ~~rising approximately 1.8%~~ with gains reaching as much as 3.6 percent due to bargain hunting in technology and automobile stocks such as Hyundai and KIA. China’s CSI 300 recorded slight gains following positive industrial production and retail sales data. Conversely, Japan’s Nikkei 225 experienced a decline, pressured by weakness in AI and semiconductor-related stocks including SoftBank Group and Tokyo Electron. In Southeast Asia, the Stock Exchange of Thailand faced downward pressure, finishing slightly lower after consecutive sessions of losses.
