Many leading stocks rallied to new highs as the market rebounded Friday to cap a dismal week with big gains. Airlines were among the top performers in IBD’s 197 industry groups. JetBlue Airways (JBLU) soared 1.03, or 5%, to 21.56 in fast trade. The stock rose for a fourth straight week and is well extended past a November breakout and multiple visits to its 10-week moving average.
