#KOSPIRisesNearly5%TriggersBuySideSidecar
August 12, 2026, South Korea's benchmark stock index, the KOSPI, surged nearly 5% intraday, triggering a temporary trading curb known as a buy-side sidecar. The market acceleration was primarily driven by a massive rally in heavyweight semiconductor and technology stocks, reviving investor sentiment across Asian financial networks.Key Market DevelopmentsThe Trigger: The Korea Exchange (KRX) activated the buy-side sidecar at 11:57 a.m. local time. This happened because the KOSPI 200 Futures index jumped more than 5% and maintained that level for over one minute.Trading Pause: The activation programmatically suspended institutional program-buy orders for five minutes to cool down rapid volatility and let the market digest the influx of capital.Chip Sector Surge: The rally defied overnight losses on Wall Street. Strong earnings from artificial intelligence infrastructure companies, such as Supermicro and CoreWeave, heavily reinforced domestic semiconductor investment.Leading Equities: Market titans led the charge. Samsung Electronics surged over 7.7%, while SK Hynix jumped roughly 7% intraday.Index Peak: During the surge, the KOSPI index rose by 315.69 points, reaching an intraday high of 6,661.22. It eventually closed the session up 3.68% at 6,579.04, marking its third consecutive winning day.$NVDA.US $NVDAB
