South Korean equity markets declined as trading resumed after the Hangeul Day holiday, driven down by rising geopolitical risk in the Middle East. The benchmark KOSPI Composite Index (KRX:KOSPI) fell more than 1% in early trading, extending its losing streak to four consecutive sessions. The sell-off was led by foreign and institutional investors, who unloaded 161.4 billion won and 11.1 billion won in net shares, respectively. Retail investors absorbed the market supply by purchasing a net 166.4 billion won.

The downturn follows an attack on Saudi Arabia by Yemen's Houthi militants during the holiday period, raising concerns over regional stability. Major technology heavyweights pulled the benchmark lower, with Samsung Electronics falling 0.86% and SK Hynix dropping 2.38%. However, select equities bucked the broader trend. LG Energy Solution advanced 3.24%, Samsung Electro-Mechanics gained 1.29%, and Celltrion rose 2.34% after delivering its third-quarter financial results before the market open. Additionally, Hanwha Machinery & Service Holdings surged over 22% on news of a tender offer by President Kim Dong-kwan.

Meanwhile, the tech-heavy Kosdaq index dropped 1.31% to 880.60, marking its third straight session of losses. Investors will keep a close eye on global geopolitical developments and institutional flow trends to see whether broader market selling pressure persists or stabilizes in upcoming sessions.
