South Korea’s KOSPI fell 10.43% over the three trading days through Nov. 6, closing at 5,059.69 after briefly entering the low 4,900s, as investors reassessed the profitability, timing and feasibility of artificial-intelligence investment following Democratic control of both chambers of the U.S. Congress. Telecom and K-content shares outperformed while semiconductors fell sharply, and a subsequent opening near the 5,000-point level was pressured by heavy foreign selling despite gains in U.S. semiconductor stocks. Analysts described the selloff as an oversold reassessment of AI investment pace and equity risk premiums rather than broad economic or credit deterioration, but said foreign flows, the won near 1,360 per dollar, U.S. technology earnings and evidence of AI demand would determine whether a technical rebound could develop.
