Wall Street in Volatility Mode

The swings in U.S. stock prices are getting wider as Wednesday's Fed policy statement approaches. The Dow has now had five straight triple-digit moves for the first time since October 2011, while the S&P has had an average daily move of nearly one percent during that time. The Fed's two-day meeting begins today with investor anxiety over the future of quantitative easing likely to grow until the Fed statement. Monday's gains for the Dow and the S&P 500 were enough to put them back in positive territory for June.

Investors will have two economic reports to ponder before the opening bell, with May housing starts and consumer prices both out at 8:30 a.m. ET.

Consumer prices had fallen 0.4 percent in April.
