ceo resignations kenichi watanabe

In the wake of an insider trading scandal, the CEO of this Japanese conglomerate resigned after four years leading the firm.

Japanese regulators were investigating Nomura for leaking information to clients ahead of planned securities offerings by energy company Inpex, Mizuho Financial Group and Tokyo Electric Power in 2010. Nomura had admitted that some employees were involved in leaking inside information.

Kenichi Watanabe announced his departure on July 26, after other executives stepped down. And markets reveled on the news that day, rising 5.7% after falling by a third since reports of the investigation surfaced four months prior.
