07:37 AM EST, 11/05/2025 (MT Newswires) -- The main US stock measures were tracking in the red in Wednesday's premarket activity as traders await a key employment report from Automatic Data Processing (ADP) and a fresh round of corporate earnings.

The S&P 500 declined 0.3%, the Dow Jones Industrial Average edged down less than 0.1% and the Nasdaq was off 0.4% before the opening bell. The indexes finished the previous trading session lower, with the Nasdaq registering its biggest one-day drop since Oct. 10.

The ADP employment report, a gauge for private-sector job growth in the US, for last month is scheduled for an 8:15 am ET release. The report comes amid the ongoing US federal government shutdown, which has already delayed the release of several key economic indicators and is likely to block the nonfarm payrolls report for October this Friday.

The stoppage entered its 36th day on Wednesday and is reportedly now the longest government shutdown in US history. The US Senate was once again unable to advance a House-passed continuing resolution to end the shutdown, CBS News reported Tuesday.

Treasury yields fell before the open, with the two-year rate retreating 1.4 basis points to 3.57% and the 10-year rate decreasing 0.8 basis points to 4.08%.

Meanwhile, the Supreme Court is scheduled to hear arguments Wednesday on whether US President Donald Trump exceeded his authority under the International Emergency Economic Powers Act, or IEEPA, to impose sweeping tariffs. In an interview with CNBC on Tuesday, Treasury Secretary Scott Bessent expressed confidence that the Trump administration will prevail.

"There are lots of other authorities that can be used, but IEEPA is by far the cleanest, and it gives the US and the president the most negotiating authority," Bessent reportedly said. "The others are more cumbersome, but they can be effective."

Trump signed an executive order on Tuesday to maintain the suspension of heightened reciprocal tariffs on Chinese imports until Nov. 10. Trump reportedly said last week he would lower duties on Chinese goods to 47% from 57%, after concluding trade talks with China's president, Xi Jinping, in South Korea.
