The S&P 500 was down 0.07%, the Dow Jones Industrial Average fell 0.02%, and the Nasdaq slid 0.12%.

Crude oil tumbled on Wednesday afternoon after President Barack Obama detailed plans to secure an Iran nuclear deal in exchange for the easing of sanctions.

Commodity traders fear that once international sanctions against Iran are loosened, Iranian oil will flood a global market already facing a supply glut. West Texas Intermediate crude closed 3.3% lower at $51.41, its lowest closing level since April.
