Dow, S&P 500 end at records despite AI fears

Banks and industrial stocks were among the best performing on the blue-chip Dow index, which ended 1.3 percent higher, while the Nasdaq lost 0.3 percent.

"Even as investors were reassured by the Fed's latest rate cut, familiar concerns about AI are still very much top of mind right now," said Deutsche Bank managing director Jim Reid.

Those concerns were reignited after Oracle reported after markets closed on Wednesday that quarterly revenue had fallen short of lofty expectations and revealed a surge in spending on data centers to boost AI capacity.

Shares in the Texas-based company finished down 10.8 percent after dropping even more during the session.

Dave Grecsek of Aspiriant Wealth Management said the market's reaction to Oracle's results underscored its discomfort with aggressive AI investments.

"There's still a lot of apprehension about how sustainable some of these capital spending plans are, what the return on those investments are, and especially now that they're financed with debt," he said.

Markets globally suffered a wobble last month with investors worried over the vast sums poured into AI, with some observers warning of an AI bubble that could burst and cause a market rout.

The Fed, as expected, cut interest rates on Wednesday. But an unusually heavy number of dissents (three) complicates the outlook for monetary policy.

"Investors have shrugged off the Fed's latest reduction in US borrowing costs as it is becoming harder to guess where rates might go next," said AJ Bell investment director Russ Mould.

Fed policymakers were highly divided about whether to cut rates again in 2026 and if so, how often.

But eToro US analyst Bret Kenwell pointed out that Fed Chair Jerome Powell had highlighted the fact that none of the Fed policymakers sees rate hikes in 2026 in their base scenario.

"The lack of an outright hawkish tone from the Fed combined with its third consecutive rate cut could pave the way for a potential year-end rally in equities, provided that next week's macroeconomic data doesn't derail the recent bullish momentum," Kenwell said.

The latest cut in borrowing costs -- to their lowest level in three years -- comes as monetary policymakers try to support the US jobs market, which has been showing signs of weakness for much of the year.

The dollar weakened while oil prices retreated.
