"It looks like a lot of investors are fairly apprehensive over the last few weeks and going into the weekend.

"Whenever you get into this gap between earnings seasons, which is not until next month, you do get a few of these overseas concerns influencing markets," said Zohny.
"Europe continues to be a concern and Asia with their monetary tightening and inflation fighting versus growth, it's also something that investors worry about."
