Asian stocks mostly fell Tuesday as technology shares came under renewed pressure, while geopolitical uncertainty and upcoming U.S. economic data encouraged investors to reduce risk.
The MSCI AC Asia Pacific index dropped about 0.5%. U.S. stock futures were firmer during Asian trading, with Nasdaq 100 futures rising 0.3% and S&P 500 futures gaining 0.1% after Wall Street closed lower Monday.
Technology stocks remained in focus ahead of Nvidia’s earnings on Wednesday. The AI chip giant is expected to report quarterly revenue of roughly $92 billion, making its results a major test of whether strong artificial intelligence spending can justify elevated market expectations.
Geopolitical concerns also weighed on sentiment after the Trump administration threatened broader secondary sanctions against countries doing business with Iran as part of its “economic D-Day” campaign. Brent crude pulled back to around $92 a barrel.
South Korea’s KOSPI fell 1.3%, with SK Hynix down 3.5% and Samsung Electronics losing 1.8%. Samsung remained under pressure after its recently announced shareholder-return plan disappointed investors.
Japanese markets performed better. The Nikkei gained 0.2% and the TOPIX rose 0.3%, although semiconductor-related shares were mixed. Kioxia advanced 0.7% and Sony added 0.4%, while TDK and Murata Manufacturing edged lower.
Australia’s S&P/ASX 200 climbed 0.6%, supported by corporate earnings. Coles gained about 2.3% following stronger-than-expected FY2026 results. Woodside Energy fell 1% despite reporting a 7% increase in first-half profit after abandoning its $5 billion clean-energy investment target. Ampol added 0.8% following Monday’s earnings-driven rally.
Elsewhere, India’s Nifty 50 declined 0.3%, while Singapore’s Straits Times gained 0.3%. China’s CSI 300 dropped 0.5%, the Shanghai Composite slipped 0.14%, and Hong Kong’s Hang Seng lost 0.3%.
Investors are now awaiting Wednesday’s U.S. PCE inflation report, the Federal Reserve’s preferred inflation gauge. Markets currently anticipate one 25-basis-point Fed rate hike by the end of 2026.
