Waltham Contributory Retirement System, Waltham, Mass., is expected to retain Essex Investment Management as manager of $12 million in active domestic small-cap to midcap growth equity, said Joseph Juppe, executive director. Trustees will make a decision at a meeting within the next month. Mr. Juppe said the $110 million pension plan has been conducting a search since June to replace the investment firm, but now believes Essex’s performance reflects the performance of the asset style as a whole. H.C. Wainwright advised on the search.
