Nike ( NKE) said its quarterly earnings rose 18%, as strength in overseas markets offset a drop in U.S. sales. The apparel and shoe maker said earnings for its second quarter rose to $152 million, or 57 cents a share, up from $129.3 million, or 48 cents a share, a year earlier. The earnings beat analysts' expectations by a penny. The Beaverton, Ore.-based company said second-quarter revenue rose 8% to $2.5 billion. The earnings follow news earlier in the week that Foot Locker ( Z), one of Nike's retail customers, was cutting back on purchases from Nike. Nike shares closed at $41.53, down 0.95%, on Thursday.
