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.

"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."
