South Korea's Kospi wavers as tech stocks rally on Nvidia earnings

South Korea's Kospi index wavered Thursday after the central bank raised interest rates again to combat inflation, while tech stocks rallied on Nvidia's strong earnings. The Bank of Korea hiked its benchmark rate by 0.25% to 3%, the highest since January last year, citing core inflation at its highest since 2023. Nvidia's revenue hit $96 billion last quarter with Q3 guidance of $106 billion, boosting chip suppliers. Samsung Electronics rose 2.50% and SK Hynix gained 3.67% on Nvidia's outlook. The Kospi has recovered from its year-to-date low of 5,280 to 6,915 points, though technical analysis suggests a possible retest of 6,000 unless it breaks resistance at 6,933.
