Buying of shares listed on South Korea’s main KOSPI market briefly halted Wednesday after the market’s futures index soared nearly six percent. 

The Korea Exchange said the sidecar order took effect at 9:06 a.m. and lasted five minutes, after the KOSPI 200 Futures Index jumped five-point-76 percent from the previous session to 322-point-20.

A sidecar order is activated when prices on the futures index deviate from standard prices by five percent or more, and when the rise or fall continues for one minute. 

This is the first time since August last year that a sidecar order for buying has been activated in the KOSPI market.

On Monday, a sidecar order for selling was activated after shares plunged more than five percent.
