Mutual funds having significant exposure to municipal bonds, which are also known as “munis,” provide an excellent choice for risk-averse investors looking to derive stable tax-free return. These funds seek to provide returns with a low level of risk by investing in municipal debt securities issued by state and local governments. These securities are believed to provide steady returns exempted from federal taxes and in many cases from state taxes as well, which is the reason why investors prefer these securities during a choppy market. Though munis are expected to provide lower yields compared to taxable bonds, they fetch better returns for investors in high tax brackets if we consider after-tax returns.
