Systematic investing has long dominated equity markets but has only recently begun to take hold in fixed income, particularly in credit. This article examines the structural barriers that historically delayed its adoption and discusses recent advances in liquidity, transparency, and trading protocols that have made systematic credit investing increasingly feasible. Through a detailed case study, we demonstrate that a rules-based portfolio using value, momentum, and sentiment signals can deliver strong risk-adjusted performance with low tracking error relative to the benchmark and complementary characteristics to traditional fundamental strategies. As asset managers seek scalable, cost-effective ways to generate alpha in an evolving market environment, systematic credit strategies are poised to become a central pillar of active credit investing. The article concludes with a discussion of how these developments are reshaping the boundaries between passive, active, and quantitative investment paradigms.
