(URGENT) Bourse operator issues sell-side sidecar on KOSPI's sharp fall

South Korea's bourse operator, the Korea Exchange (KRX), activated a sell-side sidecar on Thursday, October 15, following a sharp fall in the KOSPI index. The emergency market-stabilization mechanism was triggered to temporarily curb program trading and manage volatility amid the sudden market downturn.

Sidecars are regulatory instruments designed to protect the broader financial market from panic selling by pausing program trading orders for a set period. The swift deployment by the bourse operator underscores the severity of the downward pressure experienced by the KOSPI during the session.
