Copper futures fell the most in four weeks on signals that factory demand will ease in China, the world’s largest consumer of industrial metal.

A Purchasing Managers’ Index from HSBC Holdings Plc and Markit Economics was 49.4 in May, compared with a median forecast of 49.7 in a Bloomberg News survey of analysts.
