Technology and health care stocks have dominated the markets so far this year, while stocks in the energy sector have lagged. 

John Eade, president of Argus Research expects a cooling off of tech stocks in the second half.

"I'm not going to say [the tech sector is] in a bubble yet, but it's moving in that direction," he said. "I think the valuations are becoming a bit stretched, so I could see a bit of a pullback in tech."
