South Korea’s KOSPI closed 104.16 points, or 1.53%, higher at 6,912.37 on Aug. 27, reclaiming 6,900 as foreign investors turned net buyers in both the spot and KOSPI 200 futures markets for the first time in five sessions. They bought a net 133.3 billion won of KOSPI shares and 1.59 trillion won of futures after four sessions of cumulative selling totaling 7.77 trillion won, a shift linked to falling U.S. long-term Treasury yields and Nvidia’s stronger-than-expected results and fiscal 2028 revenue-growth guidance. Samsung Electronics rose 1.72% and SK Hynix 2.49%, while other corporates added about 1.59 trillion won of support and retail investors sold a net 1.91 trillion won. The index opened at 6,996.12 and briefly tested 7,000 before giving back gains after the Bank of Korea raised its benchmark rate by 25 basis points to 3.00%. Power-equipment and secondary-battery shares surged on U.S. policy and grid-buildout expectations, though market breadth stayed weak and a large retail overhang continued to cap rebounds. Attention turned to Federal Reserve Chair Kevin Warsh’s Jackson Hole keynote.
