Corrects the time reference on Nike's fiscal quarter.
NEW YORK (MarketWatch) -- Nike Inc. NKE -11.01% shares slumped 10% on Friday, the biggest decliner in the S&P 500 index, after the athletic-gear giant reported an unexpected fiscal fourth-quarter profit decline. Its orders for delivery, a gauge of future demand, also fell short. The percentage drop was the stock's biggest since Oct. 2008. One of Nike's customers, Finish Line Inc. FINL +9.53% , saw its shares jump 7% after the company raised its full-year per-share profit forecast. Finish Line's larger rival Foot Locker Inc. FL +3.85% rose 3.9%.
