Fuller will step down as investment chief of New York’s $209 billion pension fund after six years at the helm. Vicki Fuller has resigned as chief investment officer of the New York State Common Retirement Fund, state comptroller Thomas DiNapoli announced Friday. Fuller, who joined the $209 billion pension as CIO in 2012, will leave the fund this summer, DiNapoli said. He described her six-year tenure as an “absolute success,” noting her investment performance and “tireless concern” for the fund’s beneficiaries.
