NEW YORK — The U.S. stock market drifted through mixed trading Friday, as a zigzag week punctuated by loud threats and pullbacks finished with a quiet and tentative close.

The S&P 500 was basically flat and edged up by less than 0.1% but still notched a second straight week with a modest loss. The Dow Jones Industrial Average dipped 285 points, or 0.6%, and the Nasdaq composite rose 0.3%.

The majority of stocks on Wall Street fell, and Intel weighed on the market after tumbling 17%. The chip company reported better results for the end of 2025 than analysts expected. But investors focused instead on its forecast for the first three months of this year, which fell short of Wall Street’s expectations.

Chief Financial Officer David Zinsner said shortages of supplies are affecting the entire industry, and Intel expects available supply to hit a bottom early this year before improving in the spring and beyond. CEO Lip-Bu Tan highlighted the company’s opportunities created by the artificial-intelligence era.

Moves in the U.S. bond market were relatively modest following sharp swings early in the week, but other markets still showed potential signs of nervousness.
