U.S. markets ended Friday's trading session in the red after the release of a jobs report that missed expectations. Netflix (NFLX) was one of the worst performers on the S&P 500 this week. The streaming service which has lagged markets, was caught up in a selloff among high-momentum tech stocks including Apple (AAPL) and Google (GOOGL). Friday book-ended another week of big swings as volatility spiked on debate over when the Federal Reserve would pull the trigger on an interest rate hike. The S&P 500 threatened to enter correction territory again after falling more than nine percent from its May record. Crude oil ended the session only slightly lower after the number of active oil drilling rigs in the U.S. fell by 13. West Texas Intermediate oil was up nearly two percent for the week, its second straight weekly gain. TheStreet's Keris Lahiff reports from Wall Street.
