KOSPI Edges Higher to 5,300 as AI‑Related U.S. Weakness Fades, While Large‑Caps Diverge
Updated (55 articles)
KOSPI nudges up after week of swings The benchmark index rose 0.23% to 5,300.37 points in early trade on 4 Feb 2026, adding 12.29 points after a 6.84% surge to 5,288.08 on 3 Feb and a 5.26% plunge to 4,949.67 on 2 Feb [1][2][5]. The rally followed a five‑minute buy‑side circuit breaker triggered by the previous day’s rapid gains, marking the market’s first modest advance after a volatile stretch [3]. Analysts note that the bounce reflects renewed investor appetite despite lingering macro‑risk concerns [1].
U.S. AI software worries pressure Asian markets Overnight, the S&P 500 fell 0.84% and the Nasdaq slipped 1.43% as investors reacted to fears that AI‑driven software spending could strain profitability [1]. Anthropic’s launch of upgraded Claude capabilities for legal, sales and network tasks intensified speculation that AI could reshape the software sector, adding to the cautious tone [1]. The U.S. market dip contributed to the Korean market’s mixed sentiment, underscoring the interconnectedness of tech‑heavy indices [1][7].
Large‑cap stocks split between losers and gainers Semiconductor giants Samsung Electronics and SK hynix declined 1.73% and 1.21% respectively, echoing the broader tech pullback [1]. In contrast, Hyundai Motor surged 3.97%, LG Energy Solution rose 2.69%, and biotech firm Celltrion jumped 4.1%, highlighting divergent sector reactions to the AI‑related backdrop [1]. Financial stocks remained relatively resilient, with Hana Financial Group up 3.2% on 2 Feb, while most other blue‑chips posted modest losses [6].
Won weakens slightly amid currency pressure The Korean won traded at 1,453 per U.S. dollar in early trade, slipping 7.6 won from the previous close and extending a depreciation trend that began after the Fed chair nomination sparked risk‑off flows [1][6][7]. The currency slide coincided with a modest rise in three‑year Treasury yields to 3.152% and five‑year yields to 3.448% on 2 Feb, reflecting global bond‑market dynamics [6]. Despite the won’s weakness, the KOSPI’s modest gain suggests that investors are balancing currency concerns against sector‑specific opportunities.
Fed chair nomination and tariff talks shape sentiment The nomination of former Fed governor Kevin Warsh on 2 Feb triggered a 5% market sell‑off, prompting sell‑side circuit breakers and large outflows from foreign and institutional investors [5][6][7]. Subsequent diplomatic progress, including Prime Minister Kim Min‑seok’s tariff‑talks with the United States, helped temper fears and contributed to the 4 Feb rebound [5]. Market participants continue to monitor the Fed leadership outcome and U.S. tariff policy as key drivers of Korean equity performance [5][8].
