South Korea's bourse operator, the Korea Exchange (KRX), activated a sell-side sidecar program on Thursday, August 6, following a sharp decline in the KOSPI index.

A sidecar is a temporary trading halt designed to prevent sudden, erratic price movements from heavily impacting the broader stock market by suspending program trading buy or sell orders for a designated period.
