## Summary

Shares in Japan and South Korea fell sharply on Friday as investors feared US midterm election results could slow the artificial intelligence investment boom. The sell-off followed a steep overnight drop in US technology stocks, reflecting concern that tighter rules could disrupt data centre projects seen as important to economic growth.

Tokyo’s Nikkei 225 and Seoul’s Kospi were both down more than 6 per cent by 9.20am Singapore time. The Kospi briefly plunged 8.5 per cent to 4,923, triggering a 20-minute trading halt; Samsung Electronics fell nearly 10 per cent and SK hynix more than 11 per cent. In Japan, Tokyo Electron lost around 9 per cent and Kioxia 13 per cent, while the Nasdaq closed 5.5 per cent lower, its steepest percentage loss since April 2025.
