S&P, Nasdaq slip as tech stocks weigh

The S&P 500 and the Nasdaq were lower on Monday as declines in technology shares outweighed gains in energy and materials stocks. An upbeat jobs report on Friday helped the S&P 500 and the Dow Jones industrial average record their first four-day winning streak in about five months. The Dow closed above 17,000 on Friday for the first time since January, while the S&P was just shy of 2,000, levels that traders consider psychologically important.
