The benchmark KOSPI slipped 1.28% to around 4,004 on Thursday, reversing gains from the previous session as sentiment dampened amid renewed concerns over artificial intelligence valuations. The selloff was sparked by reports that a key investor in Oracle withdrew from the company’s data center project, sending Oracle shares down more than 5 percent and weighing on other AI-linked stocks such as Broadcom and Nvidia. Most large-cap shares in Seoul traded lower, tracking overnight losses on Wall Street, with technology and semiconductor stocks leading the decline. Samsung Electronics (-0.46%), LG Energy Solution (-6.50%), Hyundai Motor (-1.22%), and Hanwha Ocean (-2.59%) posted losses, while SK Hynix (1.18%), Samsung Biologics (1.03%), and SK Square (2.47%) saw gains. LG Energy Solution shares fell after the company was notified of the cancellation of a KRW 9.6 trillion battery supply contract with Ford Motor Co., citing policy changes and a weaker outlook for EV demand.
