In U.S. economic news, investors had hoped the minutes from the Fed's latest meeting would answer questions about when the central bank would start to pull back on its bond purchases, but they did not.

Meanwhile, existing home sales rose 6.5 percent in July from the prior month. In corporate news, Lowe's announced that its quarterly sales and profit rose from a year earlier.
