U.S. stocks pulled further back from their records on Friday to cap the weakest week for the S&P 500 since May.
Indexes sloshed between small gains and losses for much of the day before turning lower in the afternoon after Iran said it seized a British oil tanker, the latest escalation of tensions between Tehran and the West. Reined-in expectations for how deeply the Federal Reserve will cut interest rates at its next meeting also weighed on stocks.
The S&P 500 fell 18.50 points, or 0.6%, to 2,976.61.
The Dow Jones Industrial Average fell 68.77, or 0.3%, to 27,154.20.
