Rob Mann, a Singapore-based senior portfolio and macro specialist on Nikko Asset Management's Asia equity team, was promoted to head of Asia ex-Japan equity.
Mr. Mann replaces Peter Sartori, who will leave the firm in September to "pursue other interests," a news release said.
A spokeswoman for Nikko said Mr. Mann will retain his macro responsibilities.
Peter Monson, Mr. Sartori's co-portfolio manager responsible for Asia ex-Japan and China, and Eng Teck Tan, senior portfolio manager responsible for China, will both report to Mr. Mann.
