S&P 500 Wavers at Flatline After Short-Lived Rebound

It was a volatile day on Wall Street with the S&P 500 and the Nasdaq Composite reversing losses during the session. The gains, which were driven by reports that the U.S. and Iran were discussing a phased agreement to reopen the Strait of Hormuz, didn't last with the indexes trading just below the flatline. The S&P 500 was wavering at the flatline while the Nasdaq Composite dropped 0.1%.
