"By and large the stock market has acted pretty well given the increasing headwinds it's seen over the past few weeks," said Michael Sheldon, chief market strategist at RDM Financial Group. "Anytime the market is up 100 percent in the space of 24 months it’s certainty reasonable to see some profit taking, and that seems to be what we’ve experienced in recent sessions."

Sheldon added that he wouldn't be surprised to see the markets dip a few percentage points lower over the next few weeks, and said the direction of oil prices will continue to play a key role in the market's direction. But, he said, "if job creation continues to improve, that will be a very positive sign for the U.S. economy."
