The Nasdaq surged Friday and the broader market struggled at the end of the first down week in a month for Wall Street.
The Dow Jones industrial average lost 15 points, or 0.2%. The S&P 500 index added nearly 3 points or 0.3%. The Nasdaq composite rose 20 points or 1.1%.
Blue chips posted slim gains Thursday after better-than-expected reports on the labor market and manufacturing helped counter a recent batch of mixed economic news. The revived optimism remained in play Friday.
