Asia Stocks Set to Snap Longest Winning Streak Since Jan.

Asian stocks fell, with the benchmark index capping its first weekly retreat since June, as Nikon Corp.’s reduced profit forecast overshadowed a larger-than-estimated increase in China’s industrial output.

Nikon, a Japanese camera maker, slumped 14 percent, dragging consumer shares lower. BHP Billiton Ltd., the world’s largest mining company, climbed 1.8 percent in Sydney, leading raw-materials firms to the largest advance among the 10 industry groups of the Asia-Pacific benchmark gauge. DeNA Co., a mobile-game site operator, surged 11 percent in Tokyo after posting a 9.6 percent increase in first-quarter sales.
