Fidelity Massachuseets Municipal Income Fund (FDMMX)

This fund focuses on acquiring high-quality municipal bonds, dedicating at least 80% of its assets to these types of investments. The interest earned from these bonds is free from both federal and Massachusetts state personal income taxes. While the fund strategically spreads its holdings across various municipal market sectors and different bond durations, it may also concentrate more than a quarter of its total assets in municipal securities that finance comparable types of projects. It is important to note that this fund is classified as non-diversified.
