In brief
The Korea Composite Stock Price Index opened sharply lower on Tuesday, falling 3.36% to 5,662.37 in one account and 2.46% to 5,715.19 in another, as tech giants slipped and investors weighed costs of AI infrastructure amid U.S. midterm election anticipation. Oil prices dipped on expectations of a U.S.–Iran peace deal, adding to the market’s nervousness.
South Korean stocks opened sharply lower on Tuesday, with the benchmark KOSPI falling in the low‑to‑mid‑single digits as investors weighed concerns about heavy spending on artificial intelligence (AI) infrastructure and uncertainty surrounding the U.S. midterm elections.
One Reuters‑sourced report put the KOSPI down 196.71 points, or 3.36 percent, to 5,662.37 at 9:15 a.m., while a second Yonhap article reported a 143.89‑point, 2.46‑percent drop to 5,715.19. The variance shows how volatile the market perception has become.
Major technology and industrial stocks felt the pressure. Samsung Electronics fell 4.59 percent, SK hynix slid 5.10 percent, and Hyundai Motor decreased 1.57 percent. Energy and defense firms such as Doosan Enerbility and Hanwha Aerospace also slipped, each losing between 0.8 and 3.8 percent.
Analysts say that the rapid uptick in AI spending could trigger structural changes in the Korean economy. Investors are anxious that increased capital deployment may outpace demand and create long‑term macroeconomic strain.
The market mood was further dampened by U.S. stock movements, as overnight trading in the United States closed mixed. The Nasdaq Composite and the S&P 500 fell 1.07 percent and 0.51 percent respectively, while the Dow Jones Industrial Average edged up 0.41 percent ahead of Tuesday’s midterm vote.
Oil prices slipped, buoyed by optimism that a U.S.–Iran peace agreement could soon materialise. The glimmer of reduced geopolitical risk has not been enough to offset the current nervousness over tech and elections.
In another Yonhap piece, the KOSPI dropped only 0.7 percent in the first session, the steepest decline since the market reopened earlier in the year. This article highlighted that tech titans Naver and Kakao also fell 1.3 percent and 1.1 percent, respectively, in response to new AI‑related layoffs and regulatory scrutiny. Analysts warn that AI could accelerate job losses and broaden economic uncertainty.
Overall, the Seoul market remains in motion as investors continue to digest the interplay of AI spending, U.S. election dynamics, and global energy sentiment.
