Wall Street lower as consumer stocks slip

Stronger-than-expected April consumer spending data on Tuesday bolstered Federal Reserve Chair Janet Yellen's stance on Friday that a rate hike in the coming months would likely be appropriate given an improvement in the economy. Seven of the 10 major S&P sectors were lower, with the consumer staples index's 0.57 percent drop leading the decliners. The Nasdaq Composite was up 4.59 points, or 0.09 percent, at 4,938.09.
