Corning Inc (GLW): fair value, margin of safety and Wheel Score
Ticker symbol GLW · Technology · Hardware, Equipment & Parts · United States · Growth
Is GLW undervalued?
At 118.79 (close of 5 Nov 2026), GLW trades 133% over the GLS average fair value of 51.01, with 1 of 9 models above the price. The stock earns none of the Wheel Score's Value points at this price. That is a statement about price against trailing fundamentals, not about the company's prospects - the Wall Street View and the Growth tab on the Quote page carry the forward numbers.
The 9 models disagree widely: DDM gives 16.48 while Graham Growth gives 142.50. 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.
Ranked against every other company we cover, GLW is clearly faster-growing than it is cheap, so the nightly engine files it under Growth (value score 7, growth score 58, out of 100).
Nine valuation models for GLW
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 | 19.18 | -84% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 29.80 | -75% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 142.50 | +20% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 62.28 | -48% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 18.42 | -84% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 79.12 | -33% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 63.63 | -46% | Eight years of compounded free cash flow: the price at which the business pays for itself |
| DDM | 16.48 | -86% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | 27.68 | -77% | Earnings power value: current EPS capitalised at 9% with no growth |
| Zombie (liquidation) | -11.30 | -110% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 167.71 | +41% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
On financial health GLW scores 8/9 (Piotroski): most of the nine tests - positive earnings and cash flow, falling debt, rising margins and turnover - are passed, which is the kind of balance sheet a wheel trader is happy to be assigned. The GLS Moat score is 5.1 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 moderate - ROIC 7.2%, ROE 13.5%, ROA 5.2% - with debt at 0.87 times equity and a free-cash-flow yield of 2.4%.
The dividend yield is 0.94% with a payout ratio of 47% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from Optical Communications 76%, Automotive Products 15%, Life Sciences 8% (quarter Q3 FY2026).
Institutional ownership scores 9/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales; the last recorded Congressional buy was on 8 Sep 2026.
| Piotroski F-score | 8 / 9 | ROIC | 7.2% |
|---|---|---|---|
| GLS Moat | 5.1 / 10 | ROE | 13.5% |
| Debt / equity | 0.87 | ROA | 5.2% |
| Free-cash-flow yield | 2.4% | Payout ratio | 47% |
| Institutions | 9 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 47: Weak
GLW scores 47 out of 100 on the Wheel Score, in the Weak band (under 50): it fails filter 3, below fair value - trades 133% above our fair value; and filter 5, can repay its debt - 3.1 years to repay its debt (over 3), and the parts are thin too - value weak, premium strong, moat fair, health strong, red flags strong, option trading strong, stability strong. 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 61% on the near-the-money contracts 20-60 days out - above the 60% top of the sweet spot. It still passes the 25-80% filter, but the Wheel Score rewards it less because volatility this high usually comes with a reason. The option chain is deep: 317,219 contracts of open interest across all expiries, which means tight fills at most strikes.
Volume runs at 13.7M shares a day on a market cap of $102.3B, with a beta of 1.22 - 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 strong.
| 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 | Passes | Profitable over the last twelve months - not a speculative stock, fund or note |
| 3 | Below fair value | Fails | trades 133% above our fair value |
| 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 | Fails | 3.1 years to repay its debt (over 3) |
| 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 | Weak | 133% above fair value | |
| Premium | Strong | implied volatility 61% | |
| Moat | Fair | moat 5.1/10 | |
| Health | Strong | Piotroski 8/9 | |
| Red Flags | Strong | Red Flags score 90/100 | |
| Option trading | Strong | 37,670 contracts a day, 317,219 open interest | |
| Stability | Strong | beta 1.22, $102.3B company |
