The KOSPI plunged today (June 10), triggering a "sell-sidecar," which temporarily halts program sell orders.

According to the Korea Exchange, the program sell order halt was activated for five minutes at 1:16 p.m. today due to fluctuations in the KOSPI 200 futures index.

At the time of activation, the KOSPI 200 futures index was at 1,223.15, down 64.65 points, or 5.02%, from the previous day's closing price.

A KOSPI sidecar is triggered when the KOSPI 200 futures price falls by 5% or more from the reference price and sustains that level for one minute, suspending the effect of program sell orders for five minutes.

The KOSPI is continuing to show extreme volatility, with a "sell-sidecar" being triggered just one day after a "buy-sidecar" was activated during yesterday's sharp rebound.
