Overview

Brent crude slipped 1.3% to $110.23 a barrel in Asia on Oct. 26, while several regional equity indexes fell. The retreat barely reversed the recent jump, and investors now face another test as Alphabet, Microsoft and Amazon report results that may offer clues about returns on AI investment.

Brent fell 1.3% and remained above $110

The Associated Press reported Brent at $110.23 a barrel, down 1.3% in early Asian trading on Monday. It had risen 3.1% on Friday to settle at $116.72, its highest close since June 2022; in early October it was below $97. A single-day pullback has not erased the month’s climb.

Regional markets were mixed rather than moving in lockstep: Japan’s Nikkei 225 lost 0.1%, South Korea’s Kospi fell 1.1%, and Shanghai’s composite dropped 0.4%, while Hong Kong’s Hang Seng edged up 0.2%. The report linked higher energy prices to severe supply cuts from the U.S.-Iran war. One lower session is not enough evidence that the supply pressure has eased.

Big Tech has to explain what its AI spending is buying

Several AI-related stocks rose on Friday even as U.S. markets broadly fell: Micron gained 2.5%, Intel 1.7%, Microsoft 0.7% and AMD 1.7%. That uneven trading shows how investors can keep rewarding individual names without settling the larger question of whether the investment is paying off.

Alphabet, Microsoft and Amazon are due to report this week. The AP noted that some companies have borrowed to fund AI investments, while higher interest rates make that financing more expensive. Earnings will be read against two figures: how much infrastructure companies are adding, and whether their businesses are beginning to cover the cost.

Earnings can add evidence without settling the long-term return

The useful check is whether management puts new infrastructure spending, AI-related revenue and cash flow in the same account. If disclosures remain at the level of investment totals or broad demand claims, the timing and scale of any payback will still be unknown.

This week’s reports can update the near-term evidence on costs and revenue, but they may not prove what years of construction will ultimately earn. Oil is similar: one day of lower prices adds a data point; it does not establish that the supply risk has passed.
