A consecutive sell-side sidecar has been activated on Tuesday as both the benchmark Kospi and the tech-heavy Kosdaq tumbled.

The Korea Exchange activated a sell-side sidecar on the Kosdaq market at 11:37 a.m. and on the Kospi market at 11:40 a.m.

A sidecar halts program trading when certain market indexes fluctuate beyond a designated threshold.

A sell-side stoppage for the Kospi is triggered when the Kospi 200 Futures index falls 5 percent or more for at least one minute. A sell-side sidecar on the Kosdaq is activated when the Kosdaq 150 futures index fall by more than 6 percent from the reference price and the Kosdaq 150 index falls by more than 3 percent for at least one minute.

As of 11:44 a.m., the Kospi had fallen 356.48 points, or 3.91 percent, from the previous session to 8,758.07. The Kosdaq was trading at 918.94, down 49.46 points, or 5.11 percent, from the previous session.
