KOSPI Closes Up Nearly 1%; Samsung Jumps 3%, SK Hynix Gains 1.2%

Driven by a U.S. chip stock rally, South Korea's KOSPI closed up nearly 1%, with Samsung Electronics surging over 3% and SK Hynix gaining about 1.2%. Trading was active ahead of a holiday, as foreign and institutional buying lifted the semiconductor sector. The gains reflect optimism over a memory demand recovery, a short-term positive for SK Hynix, though the medium-term outlook hinges on HBM supply-demand and macro conditions.
