Investors in tax brackets higher than 28 percent fare even better with municipals.
"The glut of bonds has pushed up rates, and the municipal market right now looks like a diner who digested a large meal," said Ian McKinnon, portfolio manager of Vanguard Municipal Bond Fund -- Long Term, up 10.55 percent in total return over the past 12 months. "We see interest rates remaining stable over the next three months and then, depending on consumer confidence and the economy, likely to decline later in the year."
More municipals were downgraded by debt rating services last year than were upgraded, McKinnon noted, but he doesn't believe that's cause for concern.
Don Phillips, editor of Mutual Fund Values, a Chicago-based investment advisory, says it's important to check expenses and sales charges of any municipal fund.
"With all of those 'dark' partnership deals gone with tax reform, munis are the only game in town."
