NMCO: Buying Opportunity Has Passed, CEF Gets Another Sell Rating

An analyst maintains a Sell rating on the Nuveen Municipal Credit Opps Fund (NMCO) citing persistent underperformance, high leverage, and a narrow discount to peers. Key concerns include the fund's significant allocation to low-rated and unrated municipal bonds, which elevates risk, especially in a weaker economic environment, and weak distribution coverage largely reliant on return of capital, raising sustainability questions. Investors should also consider the potential impact of uncertain future tax law changes on municipal bond fund strategies and after-tax returns.

Analysis

A strongly negative outlook is maintained on the Nuveen Municipal Credit Opportunities Fund (NMCO), primarily driven by a combination of poor fundamentals and structural risks. The fund exhibits persistent underperformance and trades at a narrow discount relative to its peers, offering little valuation appeal to compensate for its weaknesses. Its portfolio construction is a key concern, with a heavy allocation to low-rated and unrated municipal bonds that heightens credit risk, particularly in a potential economic downturn. This risk is amplified by the fund's use of high leverage. Furthermore, the sustainability of its distributions is questionable, as a significant portion is classified as return of capital rather than being covered by net investment income, a practice that erodes the fund's net asset value over time. An external risk factor is the uncertainty surrounding US tax legislation after 2025, which could alter the tax-advantaged status of municipal bond income and impact the fund's strategy and returns.

Key Decisions for Investors

• Investors holding NMCO should consider reducing or exiting the position, as the combination of persistent underperformance, high leverage, and distributions funded by return of capital points to a high risk of continued net asset value erosion.
• Potential investors should avoid initiating new positions, given that the fund's narrow discount to NAV fails to adequately compensate for the significant credit risk within its portfolio of low-rated bonds.
• Investors seeking tax-exempt income should scrutinize the distribution sources of any closed-end fund, prioritizing those whose payouts are covered by net investment income over those reliant on return of capital.
• Monitor developments in US tax policy, as potential changes after 2025 could materially alter the investment thesis for all municipal bond funds, including NMCO.
