- South Korean chip shares fell as investors questioned the profitability of heavy AI infrastructure spending.
- Foreign investors and institutions sold South Korean equities while retail investors bought into the decline.
- SK hynix remains exposed to sentiment around global demand for memory chips used in AI systems.
SK hynix shares fell 5.03% to 1.4 million won in Seoul on Tuesday, November 3, as concerns over the profitability of large artificial intelligence infrastructure projects weighed on South Korean chip stocks. Yonhap News Agency reported that the KOSPI ended 3.59% lower at 5,648.79.
The sell-off followed renewed weakness in U.S. technology shares. Investors questioned whether the productivity and profitability of continuing AI investment would justify the scale of spending, while uncertainty ahead of the U.S. midterm elections further reduced appetite for risk.
Foreign selling deepens semiconductor pressure
Foreign investors sold a net 1.5 trillion won of South Korean equities, while institutions sold 511.7 billion won. Retail investors bought a net 1.7 trillion won, but their purchases did not offset the broader retreat.
Yonhap quoted Mirae Asset Securities analyst Kim Seok-hwan as saying that concerns about AI investment profitability persisted and that the sharp fall in U.S. chip shares on the first trading day of November weighed heavily on the Korean market. The PHLX Semiconductor Index fell 3.4% after a 7.2% decline on Friday.
SK hynix stock traded at 956.00 euros on Lang & Schwarz at 15:37:26 CET on Tuesday, November 3, 2026.
Investors should distinguish the day’s sentiment-driven pressure from the company’s underlying exposure to memory demand. SK hynix supplies products used in AI systems, leaving the stock sensitive both to long-term demand expectations and to questions about whether customers can earn adequate returns on data-center investment.
