Quick Answer: Wall Street stocks mostly rose on Oct 21 as Brent crude finished down 0.7% at US$108.79 (RM443.86) a barrel. The Dow gained more than 1% as money rotated out of tech shares, which remain under pressure from AI worries. For Malaysian investors, the move shows how oil costs and AI sentiment are shifting global portfolios.

Why Did Wall Street Stocks Rise as Oil Retreated?

Wall Street stocks rise as oil retreats, but AI jitters keep tech stocks in check — Wall Street stocks rose as oil prices eased, while AI-linked tech shares stayed under pressure.

The Dow index climbed more than 1%, led by strong results from industrial company 3M. Briefing.com analyst Patrick O’Hare called the move a “rotation” out of tech shares.

“We still have some lingering softness in the tech trade and specifically the AI space so we’re not getting a completely broad market rally,” O’Hare said. Wall Street started weakly after losing sessions in leading European and Asian markets, then gained momentum through the day.

Why Are AI Stocks Keeping Tech Shares in Check?

Tech shares have been volatile on worries over AI profitability and the heavy debt financing of some companies. The sector outperformed the market for much of 2026, which leaves it exposed to any slowdown in expectations.

O’Hare warned that “you could have really good news but it just might not be good enough to satisfy high expectations.” Investors tracking AI names can compare these signals with our AI Stock Analysis for Malaysians guide.
