Jeffrey L. Knight, the chief of global asset allocation at Boston’s Putnam Investments, has left the firm, according to the company, leaving behind a team where he oversaw some $10 billion in assets.

Knight oversaw institutional and individual portfolios at the firm and ran the asset allocation process for the company’s multi-asset class portfolios. He oversaw management of two Putnam Absolute Return funds, three Putnam Dynamic Asset Allocation Funds, the Putnam Dynamic Risk Allocation Fund, three Putnam Retirement Income Lifestyle funds (the target date series), the RetirementReady Funds and the Putnam 529 for American Funds.

Knight was the head of a 13-person team. A spokesperson says the team has worked together for 15 years and the team members taking over the leadership have been working on the portfolios.

The team will now be led by four co-heads: James Fetch, Robert Kea, Robert Schoen, and Jason Vaillancourt. Fetch has been with the company since 1994, Kea since 1989, Schoen since 1997 and Villancourt since 2000.

Knight was a two-decade veteran at Putnam, having started there in 1993 as a senior quantitative analyst. He has also been the face and voice on the company’s Capital Markets Outlook.

One of the leaders, Jim Fetch, continues to handle portfolios construction and risk.
