Korea's main bourse operator on Tuesday issued buy-side sidecars on the stock market, temporarily halting trading of futures after a sharp rise. Program trading of the benchmark Korea Composite Stock Price Index (KOSPI) was suspended for five minutes at 9:06 a.m., according to the Korea Exchange (KRX). The KOSPI 200 Futures index rose 82.6 points, or 10.84 percent, to 844 at that time. It marked the first buy-side sidecar since Feb. 3. A buy-side sidecar is triggered when the KOSPI 200 Futures index increases 5 percent or more for at least one minute. The operator also issued a buy-side sidecar for the secondary Korea Securities Dealers Automated Quotation (Kosdaq).
