Microwave Filter Company, Inc. (MFCO): fair value, margin of safety and Wheel Score
Ticker symbol MFCO · Technology · Communication Equipment · United States · Value
Is MFCO undervalued?
MFCO has a margin of safety of 52%: the stock closed at 1.30 on 5 Nov 2026 against a GLS average fair value of 2.72. 6 of the 8 valuation models that produced a number sit above the price. Our scans treat a discount this large as a strong starting point for a cash-secured put, not as a verdict - the fair value is a model output, and a wide gap can mean the models are missing something the market knows.
There is a wide gap between DCF (0.0666) and Graham Growth (8.72). 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.
Ranked against every other company we cover, MFCO is clearly cheaper than it is fast-growing, so the nightly engine files it under Value (value score 66, growth score 6, out of 100).
Nine valuation models for MFCO
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.

|---|---|---|---|
| DCF | 0.0666 | -95% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 1.48 | +13% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 8.72 | +570% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 3.81 | +193% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 0.1925 | -85% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 3.12 | +140% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 2.70 | +107% | Eight years of compounded free cash flow: the price at which the business pays for itself |

Quality and financial health
Microwave Filter Company, Inc. scores 6 of 9 on the Piotroski F-score: a middling result that passes the "Piotroski 6 or more" Wheel Trade Filter. Some of the nine tests on profitability, leverage and efficiency are failed, so the accounts are worth a look before selling a put on the name. A GLS Moat score of 2.7/10 is a weak reading: the accounts do not show returns and margins that competitors have been unable to wear down, so the Moat part of the Wheel Score contributes little.
Returns on capital are thin or negative - ROIC -19.2%, ROE -19.3%, ROA -15.7% - with debt at 0.01 times equity and a free-cash-flow yield of 11.8%.
Microwave Filter Company, Inc. pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain.
Institutional ownership scores 5/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 6 / 9 | ROIC | -19.2% |
|---|---|---|---|
| GLS Moat | 2.7 / 10 | ROE | -19.3% |
| Debt / equity | 0.01 | ROA | -15.7% |
| Free-cash-flow yield | 11.8% | Payout ratio | 0% |
| Institutions | 5 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 30: No options
No options are listed on Microwave Filter Company, Inc. in our nightly snapshot, so it fails the first Wheel Trade Filter (options that actually trade) (it reads 30, under 70) and is left out of every options scan; the fair value and health figures above are still useful for a plain stock position.
Volume runs at 5k shares a day on a market cap of $3M, with a beta of 0.15 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score rates that fair.
| Filter | Wheel Trade Filter | Result | Detail |
|---|---|---|---|
| 1 | Options that actually trade | Fails | no listed options |
| 2 | A real business, not a gamble | Passes | Profitable over the last twelve months - not a speculative stock, fund or note |
| 3 | Below fair value | Passes | Trading below the nine-model average fair value (margin of safety above 0) |
| 4 | Financially healthy | Passes | Piotroski F-score 6 or more out of 9 (a company with no score on file passes) |
| 5 | Can repay its debt | Passes | Long-term debt repaid from 3 years of operating cash flow or less (6 for real estate and utilities; banks and insurers are not judged on it) |
| 6 | No serious red flags | Passes | Red Flags score 60 or more out of 100 (earnings, margins, debt, analysts, filings and price checked the same way for every stock) |
| 7 | A premium worth selling | Fails | no implied volatility |
| 8 | Big enough | Fails | market cap $3M (under $1.0B) |
| 9 | Not a penny stock | Fails | price 1.30 (under $5) |
| How it ranks | Rating | From | |
|---|---|---|---|
| Value | Strong | 52% below fair value | |

| Moat | Weak | moat 2.7/10 | |
| Health | Good | Piotroski 6/9 | |
