TOKYO (Reuters) - Japan's Nomura Holdings more than doubled its quarterly profit on Friday, its sixth straight quarter of growth, boosted by a jump in performance at its wholesale business.

Japan's top brokerage and investment bank said net profit totalled 98.4 billion yen ($645 million) in July-September, compared to 35.2 billion yen the same period a year earlier.
