Kathleeen Gaffney, a key member of a team that invests $82 billion at Loomis Sayles & Co. in Boston, has quit to work for cross-town rival Eaton Vance Corp., according to people familiar with her resignation.
Gaffney was part of a team working for Dan Fuss, one of the nation’s most respected bond managers; The group is responsible for about half of all the fixed income money under management at the firm, including the $21.9 billion Loomis Sayles Bond fund.
Gaffney resigned from Loomis Sayles last week. News of her departure came in a Securities and Exchange Commission report filed by the company on Monday.
Gaffney had worked at Loomis Sayles for 28 years and was among the four-member team that co-managed several mutual funds and other investments for the firm’s clients.
Fuss said Gaffney told him she was leaving last Thursday. “It sounds like a good deal. I’m very sorry to lose her,” he said.
It wasn’t immediately clear what Gaffney will do at Eaton Vance, another Boston investment firm known for its fixed income management. An Eaton Vance spokeswoman did not return calls yesterday.
Gaffney could not be reached for comment Monday.
