One of the year's biggest bulls is bracing for a near-term pullback.
Federated Investors' Phil Orlando believes escalating geopolitical risks will put pressure on stocks in coming weeks. He's concerned that uncertainty surrounding Federal Reserve policy, the Mueller investigation, midterm elections and the tariff war could trigger a downside move.
"That's exactly what's on my list of things that are keeping me awake at night," he said Thursday on CNBC's "Futures Now." "With the market having run into this double top this week with a new record high, I think we run the risk of an increased chance of some volatility here as we enter this period of a fundamental vacuum."
Orlando was referring to the seasonably slow data period that could magnify risks.
"We've got six or eight weeks probably until the middle of October before we start to get any other materially positive fundamental news," he said, noting that's when the next quarterly earnings season begins.
Orlando is worried that could leave room for knee-jerk trading to the downside.
"We could see a 5 to 8 percent correction as the market gets whipped around based on what's going on with trade and tariffs, what's going on with Mueller. You know, what's going on with the Fed," said Orlando. "These are all issues that emotionally could allow some investors to lock in some near term profits here."
