Southbridge (Mass.) Retirement Board is searching for an active domestic small-cap equity manager to run $2 million. "We've had the same manager for a while and we wanted to see what else is out there," said Mary E. St. Germain, administrator. The $20 million system has the money invested in an active domestic core small-cap fund with Dreyfus, whose poor performance relative to its benchmark prompted the search, said Rafik Ghazarian, consultant with Segal Advisors, the board's investment consultant. A choice is expected in the third quarter, Mr. Ghazarian said. Calls to Dreyfus spokeswoman Patrice Koslowski were not returned before press time.
