日経平均とKOSPIが安寄り、ハイテク株の下落受けて

Asian stock markets faced immediate downward pressure on October 18, 2026, as a wave of bearish sentiment swept through regional technology shares. Japan's benchmark Nikkei index opened lower by 0.8%, slipping to 64,819.56 points amid profit-taking in high-flying semiconductor and electronics giants. Concurrently, South Korea's KOSPI index experienced similar losses, weighed down by weakness in heavyweight tech exporters. The downturn reflects persistent investor anxiety regarding slowing global demand for consumer electronics and tightening monetary conditions. Market participants are also closely monitoring currency fluctuations and upcoming macroeconomic data releases from major economies for further direction. This regional tech pullback highlights the interconnected nature of global supply chains and investor risk aversion in equity markets.
