KOSPI Falls 1.8% as AI Jitters and U.S. Weakness Whipsaw Seoul Market

Foreign selling accelerated, sending the won to a seven-month low.

Overview

  • South Korea’s benchmark closed at 3,953.76, down 72.69 points, after an intraday plunge to 3,887.32 that extended a volatile week.
  • Overnight declines on Wall Street followed renewed concern over stretched AI valuations and a report of 153,074 U.S. job cuts in October, pressuring Seoul trading.
  • Foreign investors sold 472.2 billion won on the day with institutions offloading 228.1 billion won, while retail buyers purchased 695.9 billion won.
  • The won weakened to 1,456.9 per dollar, breaching 1,450 for the first time since April as equity outflows added currency pressure.
  • Tech and cyclicals led losses, with Samsung Electronics down 1.31% and SK hynix off 2.19%, while select names such as Hanwha Ocean and Kakao advanced after stock-specific catalysts; intraday losses deepened on reports of tighter U.S. chip sales to China and softer Chinese export data.
