As of the close of business Friday, James Stetler is retiring after 39 years at Vanguard, where he has most recently served as portfolio manager of nine alpha equity mandates managed by the Vanguard Quantitative Equity Group (QEG).
The addition of Sharon Hill and Cesar Orosco as portfolio managers to the mandates in February will help ensure "a smooth and thoughtful transition," according to a Vanguard spokesman.
In addition to Stetler, Binbin Guo, principal and head of Vanguard's alpha equity U.S. investment team, is also leaving the firm, but not until late September. Guo has been a member of Vanguard's quant equity group for 14 years. He will be succeeded by Orosco as the head of the alpha equity U.S. investment team. Orosco will also serve as the sole QEG portfolio manager for the alpha equity U.S. mandates.
