Asian Stocks Fall Most in Three Weeks on China Services

Asian stocks fell, with the regional benchmark index headed for its biggest loss in more than three weeks, as a gauge of China’s services industries dropped and Japanese shares slumped on a stronger yen.

SoftBank Corp., a Japanese mobile-phone operator, slid 3.5 percent after the rating of Sprint Corp., which SoftBank acquired last year, was cut at Cowen and Company. Fast Retailing Co., Asia’s biggest apparel chain, lost 5.8 percent in Tokyo as the Nikkei 225 Stock Average slipped from a six-year high. China Railway Group Ltd. slumped 4.1 percent in Hong Kong after China’s second-largest rail builder said its president died.
