Asian Stocks Slide Despite Wall Street Tech Rally as AI Doubts and Oil Weigh

what happened

Asian stock markets kept falling on Tuesday, despite an overnight rally on Wall Street, where the S&P 500 and Nasdaq rose after a sharp pullback last week. Shares of companies tied to artificial-intelligence infrastructure lagged in Asia. SK Hynix fell 3.5%, Samsung Electronics 0.7%, Kioxia 2.4% and TSMC 0.8%. Those heavyweights pulled South Korea's Kospi down 3.4% and Japan's Nikkei 225 down 0.9%, according to Dow Jones Newswires.

Investors are becoming more selective rather than treating the whole AI chain as one trade. Chris Weston, head of research at Pepperstone, said in a note: "The market doesn't need every AI infrastructure company to succeed for the investment theme to work." Oil, meanwhile, regained momentum. ANZ Research analysts warned that improved Persian Gulf flows in the second week of October could be threatened by renewed attacks. The Wall Street Journal reported that Iran has been helping Yemen's Houthis target Saudi Arabia.

why it matters

Two forces matter for global investors here: a repricing of Asia's chip sector and renewed supply risk in energy. WTI futures rose 0.2% to $103.91 a barrel and Brent 0.3% to $109.89. Elevated crude can feed inflation concerns and affect rate expectations.
