The benchmark KOSPI rose 0.75% to close at 4,586 on Friday, extending its record-breaking run as investors continued to build positions in defense and shipbuilding shares. Defense giant Hanwha Aerospace jumped 11.38%, Korea Aerospace Industries advanced 4.90%, and HD Hyundai Heavy Industries rose 4.64%, while automakers Hyundai Motor and Kia Corporation surged 7.49% and 6.65%, respectively. Semiconductor stocks were mixed, with Samsung Electronics edging up 0.14% and SK hynix down 1.59%, reflecting some rotation out of technology shares after recent gains. Domestic institutions and individual investors stepped in to offset foreign selling, supporting the index. Meanwhile, market caution remained amid upcoming US event risks, including the payrolls report and a potential Supreme Court ruling on tariffs, but overall momentum has kept the KOSPI on track for a third straight weekly gain.
