QI Wang was promoted to chief investment officer of portfolio implementation at Pacific Investment Management Co., effective immediately.
The position is new, confirmed Michael Reid, a company spokesman.
Ms. Wang joined PIMCO in 2010 and most recently was managing director and portfolio manager, positions she retains.
In her new role, Ms. Wang oversees analytics firmwide as well as two newly created teams — portfolio implementation, and data structure and delivery.
The teams will work with PIMCO's portfolio and risk managers to "strengthen the integration of technology, analytics, risk management and execution into PIMCO's investment decisions," the firm said in a news release Wednesday.
In another internal move, PIMCO promoted Sudi Mariappa, managing director and portfolio manager, to global head of analytics, replacing Ravi K. Mattu, managing director, who will retire from day-to-day duties and serve as a consultant to PIMCO, Mr. Reid said.
Mr. Mariappa previously was PIMCO's global head of portfolio risk management activities, the news release said. He has been replaced by Josh Davis, managing director and portfolio manager.
"Qi will lead this collaborative effort to ensure all (of) PIMCO's portfolio management teams draw on our deep quantitative and analytical resources to capitalize on the increasing array of investment opportunities we now see in global markets," said Daniel Ivascyn, PIMCO's group CIO, in the release.
Ms. Wang could not be reached for more information about her new role.
PIMCO had $2 trillion in assets under management as of March 31.
