TOKYO :Japan's Nomura Holdings more than doubled its quarterly profit on Friday, boosted by strong performance at its wholesale and wealth management businesses during a quarter overshadowed by a bond trading scandal. Nomura delivered its highest profit in four years and its sixth quarter of growth, results that may take some of the sting out the recent scandal. Japan's biggest brokerage was forced to pay a regulatory fine and temporarily lost its status as a primary dealer of government bonds.
