Analyst Report

This fund tracks an index of municipal bonds, a slice of the bond market that is highly coveted due to its tax features. These bonds are generally free from federal taxes and in some cases, state and local income taxes as well making these funds crucial components of portfolios for those in high tax brackets. Muni bonds are used by local entities to pay for a variety of services or to make improvements to infrastructure paying for everything from new sewer systems to school renovations and bridge construction as such, they are relatively low risk instruments. MUB is by far the most popular fund in the national munis Category and for good reason; the fund holds over 1,200 individual securities and allocates just 5.5% to its top ten holdings ensuring high levels of diversification. Due to this MUB is a solid choice for any investor looking to gain broad exposure to the muni bond sector across a variety of states and projects around the nation.
