U.S. stocks edged lower at the opening bell on Friday, pulling major equity benchmarks back from their all-time highs, as market participants were unsure about the outcome of recent trade negotiations ahead of tariffs on Chinese imports set to kick in on Dec. 15.

The S&P 500 fell 0.1% to 3,164. The Dow Jones Industrial Average retreated 27 points, or 01.%, to 28,104. The Nasdaq Composite fell 0.1% to 8,711. Investors are monitoring a news briefing by Chinese officials that could outline Beijing's stance on the recent slew of positive trade reports. A Bloomberg report earlier said President Trump has signed off on the proposed deal Thursday afternoon, which includes a "promise by the Chinese to buy more agricultural goods." So far, Chinese diplomats and state media have not confirmed whether a partial trade deal would take place.
