Lee Kyung-min, a researcher at Daishin Securities, noted, "The domestic stock market showed strength as macro uncertainties that had limited the index's upper range eased. Foreign investors, who had been net sellers for seven consecutive trading days, turned to net buying, while institutions and financial investors expanded their net purchases, contributing to the index's strength."
He added, "With the uncertainty surrounding the monetary policy path after the September Federal Open Market Committee (FOMC) meeting calming down, U.S. long-term bond rates have stabilized downward. The yields on 10-year and 30-year U.S. Treasury bonds fell to 4.94% and 5.29%, respectively, easing pressure on the stock market."
