The benchmark KOSPI fell 0.34% to around 3,940 on Wednesday, extending its decline for a second session following overnight losses on Wall Street. The downturn in Korean equities largely mirrored the pullback in US technology shares, with investors growing increasingly cautious ahead of Thursday’s US employment report. Adding to the broader unease, Alphabet CEO Sundar Pichai voiced strong warnings about the fragility of the current AI boom. He stressed that the rapid AI surge shows signs of speculative excess and cautioning that any downturn could reverberate across the sector, with no company fully shielded. Tech heavyweights Samsung Electronics (-1.74%) and SK Hynix (-2.11%) led the decline, while energy firms LG Energy Solution (-2.03%) and Doosan Enerbility (-1.59%) posted significant losses.
