Strategies under his purview span the credit and risk spectrum, from short-duration investment-grade corporate bond portfolios to regional and global high-yield portfolios, encompassing a range of investment approaches, objectives and alpha targets, from income-oriented buy-and-hold strategies to active multi-sector total return strategies, and including both publicly traded securities and private placements in developed and emerging markets. Distenfeld is also a Partner of the firm. He co-manages AB’s multiple-award-winning High Income Fund, named “Best Fund over 10 Years” by Lipper from 2012 to 2015, and the multiple-award-winning Global High Yield and American Income portfolios, flagship fixed-income funds on the firm’s Luxembourg-domiciled fund platform for non-US investors. Distenfeld also designed and is one of the lead portfolio managers for AB’s Multi-Sector Credit Strategy, which invests across investment-grade and high-yield credit sectors globally. He is the author of a number of published papers, including one on high-yield bonds being attractive substitutes for equities and another on the often-misunderstood differences between high-yield bonds and loans. His blog “High Yield Won’t Bubble Over” (January 2013) is one of AB’s all-time most-read blogs. Distenfeld joined AB in 1998 as a fixed-income business analyst, and served as a high-yield trader (1999–2002) and high-yield portfolio manager (2002–2006) before being named director of High Yield in 2006.
