American Century Intermediate-Term Tax-Free Bond (TWTIX)
Manager Steve Permut generally sticks to high-quality bonds. But currently, the fund holds some lower-quality bonds because he believes they’re undervalued. Permut’s fairly conservative strategy has translated into steady performance over time. The fund generally doesn’t lead in the rallies or lag in the downturns. Over the past 10 years, the fund has returned an annualized 5 percent. It yields 2.2 percent and charges annual fees of only 0.48 percent.
