South Korea’s stock exchange operator, KRX, activates a sell-side “sidecar” for the KOSPI after the benchmark index falls sharply. Program trading for KOSPI-listed shares is suspended for five minutes beginning at 10:16 a.m., and the KOSPI is down 4.67% to 5,418.15 as of that time, following a weaker opening.
The triggers for the mechanism are tied to the KOSPI 200 Futures Index dropping 5% or more for at least one minute. Outlets link the sell-off to market reactions to the Democratic Party’s victory in U.S. midterm elections, which they say raises concerns about potentially tighter regulations on AI data centers. While the Yonhap items largely echo the same details, they emphasize the emergency nature of the update, while the Korea Times frames the move in the context of the policy-related concerns driving the decline.
