NUVEEN MUNICIPAL HIGH INCOME OPPORTUNITY FUND (NMZ) Stock

Nuveen Municipal High Income Opportunity Fund is a closed-end mutual fund focusing on generating high current income that is exempt from regular federal income tax. Managed by Nuveen, the fund primarily invests in a diversified portfolio of U.S. municipal securities, including both investment-grade and higher-yield, below-investment-grade bonds. Up to 75% of its managed assets may be allocated to securities rated Baa/BBB or lower, while no more than 10% can be invested in bonds rated below B3/B-, offering the fund flexibility to seek attractive yields within municipal credit markets. The fund employs leverage to enhance income potential and is actively managed, seeking undervalued sectors and credits that present favorable long-term opportunities. Its secondary objective is to pursue total return, consistent with providing tax-exempt income. Investors benefit from monthly distributions that often include interest income, and may also feature capital gains or return of capital. Established in 2004, Nuveen Municipal High Income Opportunity Fund plays a significant role for income-oriented investors seeking federally tax-exempt distributions, and it can serve as a diversified allocation within municipal bond strategies in the broader fixed-income landscape.
