Cornerstone Bancorp Inc. (CNBP): fair value, margin of safety and Wheel Score
Ticker symbol CNBP · Financial Services · Banks - Regional · United States · Value
Is CNBP undervalued?
CNBP closed at 123.00 on 5 Nov 2026, 10% below the GLS average fair value of 136.99 from 9 models (6 of them above the price). That is a moderate margin of safety: the stock passes the "below fair value" Wheel Trade Filter, with room for a bigger discount on the Value part.
There is a wide gap between Lynch (16.76) and 10 Cap (290.84). 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, CNBP is clearly cheaper than it is fast-growing, so the nightly engine files it under Value (value score 60, growth score 34, out of 100).
Nine valuation models for CNBP
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.
| Model | Value | vs price | What it measures |
|---|---|---|---|
| DCF | 144.09 | +17% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 157.42 | +28% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 130.98 | +6% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 16.76 | -86% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 88.95 | -28% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 290.84 | +136% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 232.12 | +89% | Eight years of compounded free cash flow: the price at which the business pays for itself |
| DDM | 40.46 | -67% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | 131.29 | +7% | Earnings power value: current EPS capitalised at 9% with no growth |
| Zombie (liquidation) | -878.71 | -814% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |

Quality and financial health
Cornerstone Bancorp Inc. scores 5 of 9 on the Piotroski F-score: a middling result that falls one point short of 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 7.6/10 puts CNBP among the more durable businesses we track: over up to ten years its returns on capital have stayed high, its margins steady and its balance sheet sound.
Returns on capital are moderate - ROIC 10.6%, ROE 11.8%, ROA 1.0% - with debt at 0.11 times equity and negative free cash flow.
The dividend yield is 2.24% at a payout ratio of 0%; for a wheel trader holding assigned shares the dividend adds to the covered-call premium, and the ex-dividend date is worth knowing before a call is sold.
Institutional ownership scores 5/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 5 / 9 | ROIC | 10.6% |
|---|---|---|---|
| GLS Moat | 7.6 / 10 | ROE | 11.8% |
| Debt / equity | 0.11 | ROA | 1.0% |
| Free-cash-flow yield | 0.0% | Payout ratio | 0% |
| Institutions | 5 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 25: No options
No options are listed on Cornerstone Bancorp Inc. in our nightly snapshot, so it fails the first Wheel Trade Filter (options that actually trade) (it reads 25, 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 0k shares a day on a market cap of $121M, with a beta of 0.06 - 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 | Fails | Piotroski 5/9 (under 6) |
| 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 $121M (under $1.0B) |
| 9 | Not a penny stock | Passes | Share price $5 or more |
| How it ranks | Rating | From | |
