U.S. stocks closed out their worst week since the Iran war began and their fifth losing week in a row.

The S&P 500 fell 1.7% and is now 8.7% below the all-time high it reached in January. The Dow Jones Industrial Average dropped 1.7%, and the Nasdaq composite sank 2.1%.

Crude oil prices rose again with no clear end in sight for the conflict.
