Current overview (not historical)

AI overview

The Korean KOSPI dropped 7.28% to 5,571.27 points on Friday, its sixth consecutive trading‑day decline, after opening lower on the back of a surprise‑high U.S. CPI reading and growing doubts about artificial‑intelligence‑related earnings. The index has fallen roughly 40% from its June 19 peak. Later in the session the market rebounded 3.31% to 5,738.18 points, recovering about half of the previous day’s 7.57% slide. However, a 4.5‑year high in U.S. industrial production prices has reignited expectations of a Fed rate hike, which could constrain further upside. Foreign investors sold a net 28.56 billion KRW on Thursday, reflecting continued caution amid the inflation‑Fed‑rate nexus.

    KOSPI Rebounds 3.31% but Fed Rate Hike Fears May Limit Recovery

    Report first recorded Oct 16, 12:51

    The Korea Composite Stock Price Index (KOSPI) rose up to 3.31% to 5,738.18 in Friday trading, recovering less than half of Thursday’s 7.57% drop. Speculation of a Federal Reserve rate hike, fueled by September US producer prices rising by the most in 4.5 years, could cap the rebound, leaving the index about 37% below its June closing peak of 9,114.55. Gains were led by non-AI heavyweights like Hanwha Aerospace (up 8.25%) and Samsung C&T (up 5.79%), while chipmakers like Samsung Electronics (up 2.14%) and SK Hynix (up 1.82%) lagged. KB Securities says the selloff overshot on recession and earnings fears, suggesting a possible W-shaped recovery after July's low, but selling pressure remains due to retail and foreign investor exits.

    KOSPI Drops 7% Amid Hot US CPI Data and AI Sector Doubts

    Report first recorded Oct 15, 10:27

    The Korea Composite Stock Price Index (KOSPI) opened sharply lower, sliding 7.28% to 5,571.27 by 10:13 a.m. Seoul time, extending a six-session losing streak and falling roughly 40% from its June 19 peak. This decline was driven by hotter US inflation data, where the September Consumer Price Index (CPI) reached 3.7% (above the expected 3.6%), and growing AI skepticism, which also weighed on US stocks like the S&P 500 and Nasdaq Composite. Samsung Electronics fell 6.03% and SK Hynix dropped 7.61%, while foreign investors sold a net 285.6 billion won. The inflation surprise revived fears of another Federal Reserve (Fed) rate hike at its October 27 and 28 meeting, potentially increasing borrowing costs for AI data center financing.
