Headlines from Russia and the Middle East dominated news on Friday. Russian news agency RIA quoted a senior official saying Russia is seeking to de-escalate tensions with Ukraine, followed by another report that it ended military exercises near the border with Ukraine.

Meanwhile, the U.S. military has struck ISIL artillery that had been used against Kurdish forces defending Erbil, the Pentagon said Friday.

"Equities are likely to trade sideways throughout August and be driven by geopolitical headline news," said Terry Sandven, chief equity strategist at U.S. Bank Wealth Management. "From a technical standpoint, it is a good time to add to positions as we do not expect a 10% correction at this point."

In the Middle East, Israel said Hamas had violated a 72-hour cease-fire and ordered the military to resume fire in the Gaza Strip.
