— Nike, the world’s largest maker of athletic gear, jumped $6.10, or 6.2 percent, to $105.10. It said strong demand in North America led to a 7 percent increase in revenue in the three months ended Nov. 30, balancing out economic weakness in Europe and a slowdown in growth in China.
— Micron Technology dropped 6.9 percent, the biggest decline in the S&P 500 index. The semiconductor maker reported a loss late Thursday as weaker demand for personal computers and an oversupply of certain chips hurt its sales. The stock lost 47 cents to $6.32.
