Korean Stocks Jump on US Chip Rally; SK Hynix Up About 2%

Korean stocks opened sharply higher, with the KOSPI up more than 1% and back above 7100, after a strong overnight session for US chip shares. SK Hynix rose as much as 1.63% to 1.87 million won intraday, while Samsung Electronics gained about 2% on dual buying from foreign and institutional investors. The move signals improving sentiment for memory chips and is a short-term positive for SK Hynix shares, though it reflects market correlation rather than company fundamentals, leaving the longer-term impact neutral.
