BlackRock MuniYield Quality Fund III, Inc. (MYI): fair value, margin of safety and Wheel Score
Financial Services · Asset Management · United States · High Growth
Is MYI undervalued?
At 9.78 (close of 16 Oct 2026), MYI trades 32% below the GLS average fair value of 14.39. That average comes from 8 models run on the latest filings, and 6 of them land above the current price. Margins of safety over 30% are the exception rather than the rule across the ~7,400 stocks we value each night, so the number earns BlackRock MuniYield Quality Fund III, Inc. the full Value points in the Wheel Score - and a closer look at what the market is pricing in.
There is a wide gap between EPV (5.08) and GLS Growth (27.96). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.
The nightly engine files MYI under High Growth: revenue and earnings growing fast enough that the growth-based models carry the valuation.

| Model | Value | vs price | What it measures |
|---|---|---|---|
| DCF | - | - | Present value of the projected free cash flows, discounted at the cost of capital; no value tonight |
| Graham Number | 10.90 | +11% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 26.13 | +167% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 11.42 | +17% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 27.96 | +186% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 8.00 | -18% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 15.85 | +62% | Eight years of compounded free cash flow: the price at which the business pays for itself |
| DDM | 9.80 | +0% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |

Quality and financial health
BlackRock MuniYield Quality Fund III, Inc. scores only 4 of 9 on the Piotroski F-score, which fails the Sunday Scan's "6 or more" rule. A reading this low means several of the basic tests - positive earnings, positive operating cash flow, falling debt, no new share issuance - are not met. A GLS Moat score of 2.0/10 is a weak reading: the ten-year history the score grades (revenue, EPS, book value, margins, cash flow, share count, ROIC) has not been steady, so the Moat part of the Wheel Score contributes little.
Returns on capital are thin or negative - ROIC 2.3%, ROE 3.9%, ROA 2.3% - with debt at 0.70 times equity and a free-cash-flow yield of 4.1%.
The dividend yield is high at 6.81% (payout ratio 101%) - a payout above 100% of earnings, which is not covered by profits. 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 7/10, insider activity 10/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 4 / 9 | ROIC | 2.3% |
|---|---|---|---|
| GLS Moat | 2.0 / 10 | ROE | 3.9% |
| Debt / equity | 0.70 | ROA | 2.3% |
| Free-cash-flow yield | 4.1% | Payout ratio | 101% |
| Institutions | 7 / 10 | Insiders · Congress | 10 · 5 / 10 |
Wheel Score 39: No options
No options are listed on BlackRock MuniYield Quality Fund III, Inc. in our nightly snapshot. The Wheel Score is therefore capped at 39 (it reads 39) and the stock is left out of every options screen; the fair value and health figures above are still useful for a plain stock position.
Volume runs at 2.5M shares a day on a market cap of $1.2B, with a beta of 0.64 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score gives that 16 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 25 / 25 | 32% margin of safety | |
| Health | 9 / 20 | Piotroski 4/9 | |
| Moat | 3 / 15 | moat 2.0/10 | |
| Premium | 0 / 20 | no option data | |
| Stability | 16 / 20 | 2.5M shares/day, $1.2B cap, beta 0.64 |
