Waltham (Mass.) Contributory Retirement System, with approximately $115 million in assets, is searching for an entire lineup of managers to run domestic small-cap, midcap and large-cap, and international stock portfolios, as well as alternative investments and real estate, following the approval of a new asset allocation recommended by consultant Wainwright Investment Counsel earlier this week. The system had all of its assets with State Street Global Advisors in index funds after terminating BankBoston, its sole manager, earlier this year. The new asset allocation is: domestic large-cap value, 9.4%; large-cap growth, 8.6%; midcap value, 7.9%; midcap growth, 7.1%; small-cap value, 6.2%; small-cap growth, 5.7%; EAFE, 9%; international emerging markets, 2.2%; short-term bonds, 7.3%; intermediate bonds, 9%; long-term bonds, 7.2%; high-yield bonds, 5.1%; international fixed income, 4.3%; real estate, 6%; and 5% other alternative investments, with an expected return of 11.5%. RFPs will be available at the beginning of August; the deadline for proposals is the end of August.
