The corporate bond market is larger, more illiquid, and presumably less efficient than the equity market. These features provide numerous profit opportunities for corporate bond mutual funds that are unique to the corporate bond market. However, whether corporate bond mutual funds have the valuation skills needed to take advantage of these opportunities is unclear. We introduce a novel measure to assess the valuation skills of investment-grade corporate bond mutual funds, which we refer to as the valuation accuracy score (VAS). VAS recognizes funds holding more underpriced and less overpriced corporate bonds as ex-ante having better valuation skills. It predicts future fund performance, is stable over time, and is unrelated to other sources of skill. Investors chase the performance of higher-VAS funds more aggressively and exhibit a convex flow–performance relation among these funds.

Rationality would suggest that advice-seeking investors receive benefits from costly financial advice. However, evidence documenting these benefits for US investors has so far been lacking. This article is the first to document that US mutual fund investors indeed receive one of the many previously hypothesized benefits associated with financial advice. The documented benefit comes from valuable tax-management advice that helps investors avoid taxable fund distributions and becomes even more valuable when investors face distributions that can cause large and hard-to-predict tax liabilities. Additional evidence suggests that financial advice helps with other aspects of tax management such as tax-loss selling.
