Traders also looked ahead to key employment data coming out at the end of the week and remarks from U.S. Federal Reserve chairwoman Janet Yellen.
She told a Senate panel that the U.S. economy is improving but notes that the job market remains “far from satisfactory” and inflation below the Fed’s target rate.
Yellen said that she expects low borrowing rates will continue to be needed for a "considerable time." At the same time, Yellen said geopolitical tensions, a renewal of financial stress in emerging markets and a faltering housing recovery are potential threats.
