Securities analysts said that sector-specific positive catalysts lifted South Korea’s stock market despite declines on Wall Street. Expectations that Qualcomm would sign a contract to supply artificial intelligence chips to Amazon, along with hopes that Intel would raise prices for server central processing units, supported investor sentiment toward semiconductors. As a result, SK hynix and domestic semiconductor materials, components, and equipment stocks gained ground. Expectations of benefits from a possible tightening of U.S. regulations on Chinese-made batteries also drew buying into secondary-battery stocks.
Lim Jeong-eun, a researcher at KB Securities, analyzed, "The domestic stock market showed differentiated performance driven by sector-specific momentum. Energy-related stocks were strong amid concerns originating in the Middle East, while semiconductor materials, components, and equipment stocks led the gains on KOSDAQ."
Lim Jeong-eun added, "With the size of the U.S. long-term Treasury buyback and the August producer price index (PPI) scheduled to be announced on the 10th, investors need to remain alert to stock-market volatility."
