07:53 AM EDT, 05/30/2025 (MT Newswires) -- The main US stock measures were trending lower before Friday's opening bell as investors monitor the latest developments related to President Donald Trump's tariffs and await the personal income and outlays report for April.

The S&P 500, the Dow Jones Industrial Average and the Nasdaq slipped 0.1% each in premarket activity. The indexes finished the previous trading session higher.

A federal appeals court on Thursday granted the Trump administration's request to temporarily pause a ruling that struck down most of the tariffs announced by the White House in April. The US Court of International Trade on Wednesday ruled that Trump overstepped his authority by imposing duties under the International Emergency Economic Powers Act.

"The ruling by the US Court of International Trade is so wrong, and so political!" Trump said in a social media post Friday. "Hopefully, the Supreme Court will reverse this horrible, Country threatening decision, QUICKLY and DECISIVELY."

The trade court's ruling weakens the US position in talks that were underway with more than a dozen countries, TD Economics said in a note Thursday.

US Treasury Secretary Scott Bessent reportedly told Fox News in an interview on Thursday that trade talks with China are "a bit stalled," and a call between Trump and President Xi Jinping may be needed for the two countries to reach a deal. Earlier in May, Washington and Beijing agreed to suspend most duties on each other's goods for 90 days.

Last month's personal income report is scheduled for an 8:30 am ET release. The report includes the personal consumption expenditure core price index, the Federal Reserve's preferred inflation metric.

On Thursday, government data showed that the US economy contracted at a slightly slower pace in the first quarter than initially estimated, while consumer spending growth was downgraded.

US Treasury yields moved slightly higher in premarket action, with the two-year rate rising 0.4 basis points to 3.94% and the 10-year rate inching up 0.2 basis points to 4.24%.

Friday's economic calendar also has the international trade in goods, retail inventories and wholesale inventories reports for April and the final University of Michigan consumer sentiment report for May. Preliminary results of the survey earlier in May showed that consumer sentiment hit its lowest reading in nearly three years, as inflation expectations mounted.
