Seoul shares start the week sharply mixed as investors weigh fresh US tech and semiconductor jitters against bargain-buying in Korea’s market. One Korea Times report says the KOSPI rises over 2% later in the session, closing at 5,859.08 after a weaker opening, helped by net buying from institutional investors. It cites rebounds in major chip and tech-linked names, even as investors continue to question the profitability of AI investment.

Earlier in the day, Yonhap and another Korea Times account describe a weaker open driven by declines in US tech shares and disappointment from big technology earnings, which feeds concerns about the durability of large-scale AI spending. They highlight a fall in Wall Street indexes after results from firms including Intel and Amazon, and note that KOSPI top stocks such as Samsung Electronics and SK hynix trade lower at the start. A separate Korea Times update adds that the index turns up mid-morning as bargain hunters return, while semiconductor exports remain strong, pointing to resilience in underlying trade despite the AI-focused sentiment swing. Other outlets also reference attention on upcoming US economic and political developments, including the jobs report and midterm elections.
