Seoul stocks opened Thursday at a fresh high above 6,700, driven by solid chip demand expectations following strong first-quarter earnings from Samsung Electronics and U.S. big tech firms. The benchmark KOSPI rose as high as 6,739.39 at the opening bell before adding 19.51 points, or 0.29%, to 6,710.41 as of 9:15 a.m. The index had closed at a new peak of 6,690.90 the previous day, marking three straight days of gains.
Investors bet on sustained chip demand after Samsung Electronics reported record first-quarter earnings and U.S. giants Alphabet, Amazon.com, Meta Platforms, and Microsoft beat first-quarter revenue expectations, reviving hopes for an ongoing AI boom.
