TOKYO -- Nomura Securities jumped to the top spot in the league tables for advising on Japanese mergers and acquisitions in 2017, a year when the roughly 2 trillion yen ($18 billion) deal to sell Toshiba's memory business lifted other big investment banking names.
The Nomura Holdings unit, which had ranked fifth in 2016, led by deal volume with 4.11 trillion yen ($37.7 billion), taking a 29.2% share of the market, data compiled by Thomson Reuters shows.
