Will market volatility continue? Pros weigh in

Volatility has ruled the market so far this October, and many investors are wondering if that may change when corporate earnings season gets underway this week.

So far, October has been the worst month for the Dow Jones Industrial Average (Dow Jones Global Indexes: .DJI) in the past six years. The CBOE Volatility Index (^VIX), a measure of investor uncertainty, rose as high as 22.46 on Monday, its highest since Dec. 31, 2012.

"We're at a phase where the market is trying to get its arms around this decoupling of global growth," Bryan Piskorowski, managing director at Wells Fargo Advisors, said in an interview with " Street Signs ."

Now that the U.S. is showing strength, he said, "that's upsetting the apple cart a little bit and that's what's causing this consternation in the marketplace."

While the first half of the month has not been good for the market, Piskorowski said it's hard to say right now if it will reverse course.

Jordan Posner, managing director at Matrix Asset Advisors, said corporate fundamentals are going to be very important for the next few weeks, especially since valuations have come down.

"When you look at the actual businesses, I think we'll be pretty pleased with how companies are performing," he said.

Posner thinks there may be some caution about the fourth quarter, which he said is typical.

However, "holiday may be shaping up in part, because energy prices are down for the consumer and we may actually see a continuation of decent fundamental results in the U.S.," he noted.
