South Korea's Kospi climbed 3.56% on Thursday to 6,813.34, extending its winning streak to four sessions as foreign and institutional investors bought major semiconductor shares. The benchmark added to earlier gains after opening 2.96% higher, following advances of 0.65%, 0.73% and 3.68% over the prior three sessions. Samsung Electronics rose 4.89% and SK hynix gained 5.91%, with broader support from overnight strength in U.S. AI-linked stocks and relief that the July U.S. consumer price index matched expectations, Shinhan Securities analyst Kang Jin-hyeok said. Trading volume reached 416 million shares worth 34.45 trillion won ($24.22 billion), while the won weakened 3.7 won to 1,419.4 against the dollar. Government bond yields also fell, with the three-year Treasury yield down 1 basis point (0.01 percentage point) to 3.781% and the five-year yield off 0.9 basis points to 4.016%.
