When it comes to investing in municipal bonds, the Fidelity Intermediate Municipal Income Fund (FLTMX) has a "steadfast" approach that has served investors well, according to Morningstar. They look at the yield curve, credit quality and structure of the bond when assessing assets, he added. The result is a 45.5% allocation to AA-rated munis, 31% in A-rated and 7% in BBB-rated municipal bonds. The team also makes a lot of small bets instead of relying on big investments that can make or break a portfolio, Maka added. So we've been buying some of those deep discount securities that were hit hard as rates rose," Maka explained.
