Nomura shakes up management

Siggi Thorkelsson has quit his post as Asian head of equities at Nomura Holdings, as the Japanese brokerage yesterday announced a management shake-up that included a new US chief to drive growth there.

Nomura said Naoki Matsuba will take over as CEO for the Americas to drive its build out in the United States. Matsuba, currently head of global equities, will also continue to manage that business as co-head.
