Neuberger Berman Group has introduced a new fixed-income mutual fund that promises to explore every nook of the bond market in pursuit of positive absolute returns. Rather than limit itself to a particular benchmark, the actively managed Neuberger Berman Unconstrained Bond Fund (NUBAX) will pursue opportunities in all fixed-income sectors — from U.S. Treasuries to emerging markets and high yield — and adopt both long and short positions. "Our fund utilizes a broad set of tools to take advantage of market mispricing," said Tom Marthaler, managing director and co-manager of the fund. "This flexibility provides us with the ability to express investment views and to have positive, negative or zero duration."
