Seoul Triggers Buy Sidecar for 2nd Day as KOSPI Briefing Reclaims 7,000
On Wednesday, July 22, 2026, extreme volatility continued across Asian equities. The South Korean benchmark KOSPI gained 0.74% to close at 6,797.70. However, the index witnessed dramatic intraday swings, surging over 4% during early morning trading to briefly breach the 7,000-point milestone for the first time in four sessions. The rapid upward momentum triggered a “buy-side sidecar” for the second consecutive day, temporarily suspending program buy orders to cool market overheating.

Semiconductor Inflows and Infrastructure News Fuel Rally
The early morning surge was anchored by heavy foreign net buying in market giants Samsung Electronics and SK Hynix, following overnight Wall Street gains in chipmakers (such as Nvidia, Micron, and SanDisk). Optimism was further reinforced by South Korean government announcements to fast-track power and water infrastructure for the Yongin Semiconductor Mega Cluster by over a decade. However, afternoon profit-taking by domestic retail and institutional investors trimmed gains prior to the market close.
