Do fixed income mutual fund managers have managerial skills?

Motivated by Berk and Green Berk, J., & Green, R. (2004). Mutual fund flows and performance in rational markets.

Quarterly Journal of Economics, 114, 389–432] who show theoretically that performance persistence may be short-lived, we complement Bollen and Busse Bollen, N., & Busse, J. A. (2004). Short-term persistence in mutual fund performance. Review of Financial Studies, 18, 569–597] and examine performance persistence in high-quality corporate-bond mutual funds over short horizons. Empirically, we find supporting evidence of performance persistence over shorter horizons. Our empirical tests also suggest that the performance persistence we document may be at least partly due to managerial skills.
