Morningstar Municipal Bond Overview

Morningstar Municipal Bond (MSTPX) is an actively managed Municipal Bond Muni National Interm fund. Morningstar launched the fund in 2018.

The investment seeks income exempt from federal income taxes as well as capital preservation. The fund will invest at least 80% of its net assets, plus borrowings for investment purposes, in securities of municipal issuers within the United States and its territories, the income of which is exempt from U.S. taxation. The Advisor intends to invest primarily in investment-grade municipal securities. The fund may also invest in derivatives, including options, futures, swaps, and inverse floating-rate debt instruments (inverse floaters), for risk management purposes or as part of its investment strategies.

Assets Under Management

The fund has $331 million in total assets, which is below the $1 billion average for the Muni National Interm category.

Morningstar Municipal Bond has an expense ratio of 0.58%, which is 15% lower than its category average, making the fund expense ratio grade a C. While it is difficult to predict returns, it is known that high annual expense ratios reduce your rate of return, and excessive fees are difficult to overcome. Active management normally comes with higher expense ratios than passive index management. Certain investment categories such as small company and foreign also normally have higher expense ratios. It is best to compare fund expense ratios against the category averages for meaningful assessments.
