Asian stocks declined on Tuesday with South Korea leading losses after Samsung Electronics’ forecast triggered a reassessment of stretched valuations tied to the AI trade, while oil prices largely stabilised as investors refocused on supply and demand.
Samsung Electronics, the world’s largest memory chipmaker, estimated April-June operating profit at 89.4 trillion won (€51.22 billion), an eye-popping 19-fold jump and a third straight quarter of record operating profit.
Still, South Korean shares slumped 8 per cent, triggering circuit breakers as Samsung Electronics lost 9.8 per cent, reflecting concerns over the durability of the AI-driven chip boom.
The AI jitter rippled across Asian markets, with MSCI’s broadest index of Asia-Pacific shares outside Japan falling 2.6 per cent and chipmaker-heavy Taiwan down 1.8 per cent. Japan’s Nikkei shed 2.4 per cent.

The recent sharp rally in AI-related shares has likely been driven by concerns over the economy and inflation, with worries about the outlook — including worsening tensions involving Iran — prompting investors to seek refuge in the sector, said Toru Suehiro, chief economist at Daiwa Securities.
“While it would be healthier for share prices to move in line with business conditions and the real economy, those conditions do not change that rapidly,” Suehiro said in a note, adding that markets were therefore likely to remain range-bound. Morgan Stanley said in a note dated Monday that the recent weakness in US semiconductor stocks is a sign that market gains are broadening, with investors likely to turn toward AI “hyperscalers” as well as consumer discretionary, transport and biotechnology shares.
