U.S. Labor Market Expansion Moderated In December, Supreme Court's Tariff Ruling In Focus

Stocks on Wall Street lacked momentum on Friday ahead of a jobs report and a potential U.S. Supreme Court ruling on trade tariffs. 

The S&P 500 index edged up a fraction, and the tech-heavy Nasdaq Composite inched lower as investors rotated away from high-flying artificial intelligence stocks. 

December nonfarm payrolls are likely to increase between 45,000 and 50,000 as the healthcare and professional services continue to expand. 

However, investors are also bracing for a sharp downward revision in November and September payrolls data as the statistical office processes a wider set of survey responses. 

The U.S. Supreme Court is likely to strike down the Trump administration's global tariffs, confirming rulings from two lower courts. 

The apex court sent mixed signals during cross-examination of the U.S. solicitor, and most court trade policy analysts are hoping that the court's ruling could force the Trump administration to levy new tariffs using a different set of rules. 

The adverse ruling from the court could also impact the financial position of the U.S. federal government, as most of the tariff revenue has been used for government spending and interest payments. 

 

U.S. Movers 

General Motors decreased 0.9% to $84.49 after the company disclosed a $7.1 billion charge in the fourth quarter of 2025 linked to its electric vehicle operations and restructuring in China.
