Thomas O’Neill, chief investment officer at FleetBoston Financial, resigned effective July 31 to run a hedge fund he created two years ago, the Navigator Fund. FleetBoston would like to have a new CIO in place when Mr. O’Neill leaves, but a successor has not yet been determined, said Charles Salmans, FleetBoston spokesman. Mr. O’Neill became CIO at FleetBoston last year when Fleet merged with BankBoston; he has been CIO at Fleet since 1995.
