Middlesex County Retirement System, Cambridge, Mass., hired a slew of managers following recent changes in its asset allocation. The $520 million fund hired, to run $15 million each: Meridian Investment as an emerging manager; Batterymarch for small-cap growth; Seneca, domestic midcap growth; Fisher, small-cap value; and Boston Partners, midcap value. Money for the new managers came from cutting back the fund’s allocation to domestic large-cap stocks, international stocks and international fixed income, said Gus Aristizabal, chief operating officer, at Wainwright Investment Counsel, the fund’s consultant.
