Seoul: South Korean stocks closed markedly higher Monday, led by semiconductor shares, rebounding from the previous session's dip, as valuation concerns over artificial intelligence (AI)-related stocks eased somewhat. The local currency weakened against the U.S. dollar. The benchmark Korea Composite Stock Price Index (KOSPI) added 77.68 points, or 1.94 percent, to close at 4,089.25.
According to Yonhap News Agency, trade volume was moderate at 337.99 million shares worth 14.1 trillion won (US$7.44 billion), with losers beating winners 490 to 392. The index opened higher following a sharp decline the previous session and maintained the momentum on solid buying by offshore investors. Foreign investors bought a net 518.18 billion won worth of shares, while retail and institutional investors sold a net 492.06 billion won and 5.7 billion won worth of shares, respectively.
"The news that Samsung Electronics raised prices on some memory chips has been interpreted as a sign that AI-related chips are in short supply and demand is expected to rise further. It seems to help ease some fears of an AI bubble," said Seo Sang-young, an analyst at Mirae Asset Securities. "Nvidia is projected to announce better-than-expected earnings, and the focus now is on how the company will shape the narrative for the sector," he added.
Market bellwether Samsung Electronics rose 3.5 percent to 100,600 won, and chip giant SK hynix surged 8.21 percent to 606,000 won.
