KOSPI Surges 4%, Buy Sidecar Triggered
On Oct. 27, the KOSPI surged more than 4% in intraday trading, prompting the Korea Exchange (KRX) to activate a buy-side sidecar that suspended program trading for KOSPI-listed shares, according to Yonhap and the Korea Times. KBS World reports the index gained 232 points as investor sentiment toward semiconductors recovered, while Business Korea notes the market rebounded above 5,600 on tech buying, breaking from the previous day's steep decline. Korean media frame this as a sharp rebound driven by AI infrastructure optimism and chip-sector strength, with Samsung Electronics' profit surge under Lee Jae-yong's leadership cited as a key factor. However, Business Korea also highlights that trading value hit a 2026 low, reflecting deepening investor caution despite the rally.
