Looking ahead to the rest of the week, investors are awaiting the U.S. October jobs report from the Bureau of Labor Statistics. The report, due out Friday morning, has a strong influence on market sentiment.

Investors are zeroing in on the economy as they attempt to gauge when the Federal Reserve will begin to slow, or taper, the pace of its $85 billion per month stimulus program.

The Fed is expected to stay on hold until sometime next year, but any sign of improvement in growth, particularly in the job market, could stoke concerns about an early exit.

"We all know the taper is coming, we just don't know when," said Stone.
