He believes U.S. stocks are a little overvalued right now and thinks global investors looking at Europe may get a bit of a tailwind from the low euro.
"We're going have to see how the economy improves, and perhaps earnings for U.S. companies to get the market going again," said Williams, USAA's chief investment officer for investment solutions.
Julian Emanuel, executive director of U.S. equities and derivatives strategy at UBS, said investors are looking to what's ahead in March.
With the low euro and a sense that Europe has to prove that it can grow, and a Federal Reserve that may or may not indicate at its next meeting when it will hike rates, "it's just a time to pause, and I think we're taking profits here," he said.

As for the strong U.S. dollar and its impact on multinational companies, it is "definitely a concern that is out there," Emanuel said. However, the foreign exchange hit has already been factored into earning expectations, he added.
Therefore, "if we do get stability then earnings could surprise to the upside," he said.
He likes the health care and technology sectors.
Williams has his eye on energy stocks. He thinks the drop in oil prices was caused, in part, by Saudi Arabia and believes prices should reverse over the course of the next year.
"Realizing that oil is a very cyclical business, we're in a downturn, this is probably a pretty good time to start buying energy stocks and wait for that upturn," he said.
Williams likes Schlumberger, Occidental Petroleum and Carnival, which he said has been a beneficiary of low oil.
