Seoul Composite Index extends gains to 3%

A 3% move in the KOSPI is a notable single-session swing for a benchmark that rarely travels that far, so the breadth of the advance matters more than the headline number. With no driver or sector detail disclosed, it is unclear whether this reflects a broad regional risk-on shift across Asian equities or something Korea-specific. That distinction determines whether the move has staying power or fades with the session. What's worth watching is whether follow-through appears in subsequent trading and whether the rally proves broad-based rather than concentrated.
