Rivernorth Managed Duration Municipal Income Fund Inc. (RMM): fair value, margin of safety and Wheel Score

Is RMM undervalued?

Rivernorth Managed Duration Municipal Income Fund Inc. (RMM) closed at 13.25 on 5 Nov 2026. The GLS average fair value - the simple average of the 8 valuation models that produced a positive number - is 24.94, which puts the price 47% below it. 5 of the 8 models value the shares above the current price. A gap this wide is rare in our universe of ~7,400 US stocks and is exactly what the Value part of the Wheel Score rewards; it is also where the question "why is it this cheap?" matters most.

The 8 models disagree widely: GLS Growth gives 4.97 while Graham Growth gives 83.58. A spread that wide means the average is sensitive to which methods you trust; the model table below shows where each one lands, and the Quote page lets you switch any of them off.

RMM looks like a fund, note or preferred share rather than an operating company, so the nightly engine files it under Fund / Note: the valuation models are not built for it, and its Wheel Score is capped at 45.

Nine valuation models for RMM

Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.

Quality and financial health

Financial health is average - RMM passes 6 of the nine Piotroski tests, which passes the "Piotroski 6 or more" Wheel Trade Filter. The Financials tab on the Quote page shows which tests fail. There is no GLS Moat score for RMM: funds, notes and second share lines get none, and so does a company with fewer than two years of accounts on file. The Moat part of the Wheel Score is zero.

Returns on capital are moderate - ROIC 6.7%, ROE 11.1%, ROA 6.6% - with debt at 0.65 times equity and a free-cash-flow yield of 3.3%.

The dividend yield is high at 7.76% (payout ratio 62%). A yield this size is often the market's way of pricing a risk to the payout, so the health score and cash flow matter more than usual.

Institutional ownership scores 2/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.

Wheel Score 28: No options

RMM has no listed options in the nightly snapshot, so there is nothing to sell and the stock cannot be wheeled however good the business. It fails the first Wheel Trade Filter (options that actually trade), so the score stays under 70 and is shown as "No options" (28 here). The valuation and quality numbers still apply to owning the shares outright.

Volume runs at 61k shares a day on a market cap of $262M, with a beta of 0.77 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score rates that fair.

The Wheel Score ranks ~7,400 US stocks for selling cash-secured puts and covered calls: a stock must pass all 9 Wheel Trade Filters to score 70, and the score then ranks the ones that pass; the Sunday Scan is the top 10. It is updated nightly and is not a recommendation. How the Wheel Score works · the walkthrough lesson shows how it fits into a trade, start to finish.

Upcoming events

No upcoming earnings date is recorded for RMM in the nightly calendar. The shares go ex-dividend on 16 Nov 2026 (0.0847 per share), so a covered call sold before then carries a small early-assignment risk around that date.
