Stocks sputter as Yellen testifies before Congress

Stocks declined in morning trading Tuesday as investors digested Federal Reserve Chair Janet Yellen's semi-annual economic report to Congress. Yellen raised the possibility that the Fed could lift its key short-term interest rate should the labor market improve faster than anticipated, but she also said the economy needs to strengthen before the Fed raises interest rates.

The Standard & Poor's 500 index fell seven points to 1,969 as of 11:45 a.m. Eastern Time. The Dow Jones industrial average slipped 20 points, or 0.1 percent, to 17,036. The Nasdaq composite slid 34 points, or 0.7 percent, to 4,407.

"In light of corporate earnings being good, retail sales being good, manufacturing being good, even a data-driven Fed chairman is going to have to raise rates earlier than the market really wants," said Doug Cote, chief market strategist at Voya Investment Management. "So all the good fundamental data that should be good for the markets is also hawkish for rates."

Yellen told Congress that the Fed intends to keep providing significant support to the U.S. economy to boost growth and improve labor market conditions, noting that the economic recovery is not yet complete.

Employers added 288,000 jobs last month, the fifth straight month of gains above 200,000. The national unemployment rate has slid to 6.1 percent, a 5 1/2-year low. Yellen noted that if labor market conditions continue to improve more quickly than anticipated, the Fed could raise its key short-term interest rate sooner than currently projected.
