Factor-driven, trend and pure alpha are among the sleeves within systematic investing that can fuel returns. Jeffrey Rosenberg, managing director and senior portfolio manager for BlackRock Systematic, has spent years identifying and mining such returns. He joins Bloomberg Intelligence’s Noel Hebert on Credit Crunch to discuss the evolution of systematic investing, defensive alpha, the opportunity in high-dispersion markets, the evolving microstructure of credit and BlackRock’s “glass box” approach. That and more in this latest episode. Credit Crunch is part of the FICC Focus podcast series.
