KOSPI Rises as Hynix Gains 6.69% and US Chip Stocks Advance
Key Facts
The KOSPI rose on November 10 as semiconductor shares advanced, in a session that saw foreign investors return to buying after 8 sessions of net selling. Foreign investors bought a net 353.2 billion won in shares, while institutions recorded net purchases of 498 billion won. Individual investors, by contrast, sold a net 1.34 trillion won in shares, according to The Korea Times. The session showed a clear divergence between institutional and individual flows, as chipmakers and electric power equipment stocks rose. The KOSPI closed at 5,018.85 points in the previous session, on November 9, according to EL7 data.
SK Hynix rose 6.69% to close at 1,212,000 won, while Samsung Electronics gained 4.74% to 198,900 won. The Korean gains followed a 6.9% rise in the Philadelphia Semiconductor Index in the previous US session, according to The Korea Times. The newspaper linked the rebound to easing Middle East tensions and gains in US chip stocks, factors that restored risk appetite to the market. West Texas Intermediate futures also fell below $87 a barrel. Electric power equipment companies also posted strong gains during the session.
Hyosung Heavy Industries rose 12.72%, HD Hyundai Electric gained 10.67%, and LS Electric advanced 8.33%. The Korea Times cited improving sentiment toward the artificial intelligence value chain as a factor behind the companies’ gains. In the currency market, the won rose to 1,337.5 against the dollar, up 9.6 won from the previous session. The moves in stocks and currencies reflected improved appetite for Korean assets that day. Individual investors, however, remained net sellers despite foreign and institutional buying.
US stocks posted broad gains on November 9, with the S&P 500 rising 2.4%, its biggest daily increase since April, according to a report attributed to Reuters and published by Investing.com. The Philadelphia Semiconductor Index also rose nearly 7% as investors bought chip stocks after the previous week’s decline. The Korea Times quoted an analyst at Kiwoom Securities as saying that concerns about artificial intelligence and semiconductor company earnings had been largely reflected in prices. He added that sentiment remained vulnerable to short-term price moves. The Philadelphia index had risen 6.9% in the previous US session, according to the newspaper.
Investors turned their attention to the US October Consumer Price Index report, due on November 10, with inflation expected to rise to 3.9% from 3.7% in September, according to the Associated Press. The report put the US inflation trajectory among the data investors tracked during the KOSPI session. TSMC also listed its October 2026 monthly sales announcement on investors’ calendars for November 10. That offers a near-term indicator of activity at a pivotal company in the semiconductor sector. The forthcoming data kept the market focused on US inflation and industry information, alongside investor flows in Korea.
