The S&P 500 and Nasdaq rebounded from session lows after Reuters reported US and Iranian negotiators were exploring a phased path out of war that would involve Iran reopening the Strait of Hormuz and the US lifting its economic blockade of Iran.

US and Iranian leaders exchanged barbs this week at the United Nations General Assembly.

Treasury yields rose, with the 30-year Treasury bond yield reaching its highest since 2004.

Higher yields make safe-haven Treasuries relatively more attractive to investors than stocks with uncertain returns.
