Market Overview
Korean equities delivered a mixed session, with the KOSPI advancing to 8,710.72, up 1.93%, while the KOSDAQ fell to 1,017.82, down 1.57%. The split performance suggested a market led by large-cap strength and selective momentum rather than broad risk appetite across all segments.

- Construction and policy-sensitive trades: Daewoo Engineering & Construction rose sharply, with reference coverage highlighting senior housing business expansion and renewed attention on reconstruction-related names.
- Technology and component interest: AUK stood out among electronics component names, while Samsung Electronics remained a major market bellwether with a modest but report-worthy gain.
