The Kospi triggered a buy-side sidecar — a temporary suspension of program buy order prices — on Monday morning as the index surged sharply during the session.
Korea Exchange announced it activated the buy-side sidecar on the Kospi market at 11:30:32 a.m. Monday.
At the time of activation, the relevant futures contract was trading at 1,417.90 points, up 67.90 points, or 5.02 percent, from the base price of 1,350.00 points.
A buy-side sidecar is triggered when the price of a futures contract based on the Kospi 200 — specifically the issue with the highest trading volume on the previous session — rises 5 percent or more above its base price and holds that level for at least one minute.
Under the sidecar, program buy asking prices on the Kospi market are suspended for five minutes. The mechanism is a market stabilization tool designed to counter sudden spikes in volatility.
