Owens Corning (OC): fair value, margin of safety and Wheel Score
Ticker symbol OC · Basic Materials · Construction Materials · United States · Speculative
Is OC undervalued?
At 127.80 (close of 5 Nov 2026), OC trades 28% under the GLS average fair value of 178.38. 1 of the 3 models that produced a value land above the price. A discount of this size counts as a positive margin of safety in every GLS scan; whether it is enough depends on the rest of the picture - the health score, the moat and the option premium below.
Only 3 of the nine models produced a value (DCF, 10 Cap, DDM); the others need a dividend, positive free cash flow or positive book value the company does not have yet, so the average rests on a narrow base.
The nightly engine files OC under Speculative - it is losing money or its Piotroski health score is 3 or lower - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.
Nine valuation models for OC
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 | 103.40 | -19% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | - | - | The most a defensive investor pays for the earnings and book value per share; no value tonight |
| Graham Growth | - | - | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields; no value tonight |
| Lynch | - | - | EPS × the earnings growth rate (PEG of 1), growth capped at 25%; no value tonight |
| GLS Growth | - | - | EPS compounded ten years at the blended growth rate, discounted back at 15% a year; no value tonight |
| 10 Cap | 385.24 | +201% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | - | - | Eight years of compounded free cash flow: the price at which the business pays for itself; no value tonight |
| DDM | 46.50 | -64% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | - | - | Earnings power value: current EPS capitalised at 9% with no growth; no value tonight |
| Zombie (liquidation) | -72.64 | -157% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 143.00 | +12% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is weak: OC passes 4 of the nine Piotroski tests. Our scans drop the stock at the health filter; a low score is often the reason a stock looks cheap on the valuation models. The GLS Moat score is 6.9 out of 10: a record that is solid on some of the four parts the score weighs (returns on capital, pricing power, lasting growth, balance sheet) and weaker on others.
Returns on capital are thin or negative - ROIC -5.2%, ROE -13.5%, ROA -4.0% - with debt at 1.60 times equity and a free-cash-flow yield of 10.3%.
The dividend yield is 2.47% at a payout ratio of -58%; 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. Revenue comes mainly from Roofing 47%, Insulation 35%, Doors 18% (quarter Q2 FY2026).
Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 1/10 on the GLS smart-money scales.
| Piotroski F-score | 4 / 9 | ROIC | -5.2% |
|---|---|---|---|
| GLS Moat | 6.9 / 10 | ROE | -13.5% |
| Debt / equity | 1.60 | ROA | -4.0% |
| Free-cash-flow yield | 10.3% | Payout ratio | -58% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 1 / 10 |
Wheel Score 48: Weak
OC scores 48 out of 100 on the Wheel Score, in the Weak band (under 50): it fails filter 2, a real business, not a gamble - speculative (a loss, or a weak Piotroski score); and filter 4, financially healthy - Piotroski 4/9 (under 6), and the parts are thin too - value strong, premium strong, moat good, health fair, red flags good, option trading weak, stability good. The score is not a judgement on the company; it says the price, quality and premium do not line up for selling puts on it today.
Implied volatility is 44% on the near-the-money contracts 20-60 days out - inside the 35-60% sweet spot the Wheel Score rewards most: enough premium to be worth selling, not so much that the risk is unpaid. Chain open interest is 3,868 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 3.5M shares a day on a market cap of $10.1B, with a beta of 1.31 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score rates that good.
| Filter | Wheel Trade Filter | Result | Detail |
|---|---|---|---|
| 1 | Options that actually trade | Passes | Listed options with 1,000+ contracts of open interest and 100+ traded a day |
| 2 | A real business, not a gamble | Fails | speculative (a loss, or a weak Piotroski score) |
| 3 | Below fair value | Passes | Trading below the nine-model average fair value (margin of safety above 0) |
| 4 | Financially healthy | Fails | Piotroski 4/9 (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 | Passes | Implied volatility 25-80% (enough premium, not a lottery ticket) |
| 8 | Big enough | Passes | Market cap $1 billion or more |
| 9 | Not a penny stock | Passes | Share price $5 or more |
| How it ranks | Rating | From | |
|---|---|---|---|
| Value | Strong | 28% below fair value | |
| Premium | Strong | implied volatility 44% | |
| Moat | Good | moat 6.9/10 | |
| Health | Fair | Piotroski 4/9 | |
| Red Flags | Good | Red Flags score 80/100 | |
| Option trading | Weak | 522 contracts a day, 3,868 open interest | |
| Stability | Good | beta 1.31, $10.1B company |
