The KOSPI sank below 8,000 on July 2, prompting KRX to activate a sell-side sidecar and suspend program trading for five minutes. The index was down 534.25 points, or 6.43%, to 7,769.16 by 9:51 a.m. local time. Heavy semiconductor selling drove the move after the VanEck Semiconductor ETF lost 5.4% Wednesday. By late June, KRX had logged close to 30 sidecar activations and five circuit breakers this year.
