KEEPING SCORE: The Dow Jones industrial average fell 20 points, or 0.1 percent, to 18,194 as of 12:11 p.m. Eastern. The Standard & Poor’s 500 index rose less than one point at 2,111. The Nasdaq composite was down six points, or 0.1 percent, at 4,981.

THE QUOTE: “The market does not have a clear catalyst to either cause it to sell off or to surge forward, and we’re getting a little expensive from a valuation perspective,” said David Heidel, regional investment director at U.S. Bank Wealth Management.

WEAKER GROWTH: The Commerce Department said that the U.S. economy grew at an annual rate of 2.2 percent in the October-December quarter, weaker than the 2.6 percent first estimated last month.

CONFIDENCE SLIPS: Consumers’ confidence slipped this month, though it remains at the highest level in eight years.
