RT Journal Article SR Electronic T1 Predicting Municipal Bond Fund Returns JF The Journal of Investing FD Institutional Investor Journals SP 53 OP 65 DO 10.3905/joi.2002.319513 VO 11 IS 3 A1 Dale L. Domian A1 William R Reichenstein YR 2002 UL https://pm-research.com/content/11/3/53.abstract AB This article examines municipal bond fund returns from 1991 through 2000. Four predictions of the efficient markets hypothesis are supported. First, among similar-style funds, there is a consistent negative relationship between expense ratios and net returns. Second, on average, a 1% higher expense ratio reduces returns by about 1%. Third, load funds do not provide higher net returns than no-load funds. Fourth, expense ratios consistently predict relative fund returns for one-year through five-year investment horizons. In addition, the authors present multiple regressions for a large sample of funds across fixed-income styles. While the influences of duration, average credit quality, and tax status are time dependent, a lower expense ratio produces a persistent advantage year after year after year.
