U.S. stocks tumbled Wednesday, dropping more than 1 percent after crude declined to a new five-year low, and at least one market pro thinks shares have further to fall.
"We've had a pretty good run off the low in October and it doesn't surprise me right around mid-December we have a pullback," Morgan Stanley's Andrew Slimmon told CNBC's "Closing Bell."
"Will we have the same level? No. But could we have a pullback of 5 percent? I think that's a real possibility."
Quantitative Management Associates' Ed Keon suspects this is a short-term pullback.
"We'll head back up again pretty soon," he said.
