Seasoned US BSL CLO Managers: Inception-to-date Alpha Trends

In year-to-date 2025 and throughout 2024, managers have, on average, broadly tracked the loan index across all three inception-to-date annualised metrics: total return, market value (MV) return, and interest return. The benchmark loan index used is the Morningstar LSTA U.S. B/BB Ratings Loan Index. Nonetheless, several managers—such as OHA, Golub Capital, and UBS AM—have continued to distinguish themselves with above-average inception-to-date alpha since 2020, while others have consistently lagged behind the index.
