Corning Inc (GLW): fair value, margin of safety and Wheel Score
Technology · Hardware, Equipment & Parts · United States · Blend
Is GLW undervalued?
At 138.36 (close of 16 Oct 2026), GLW trades 195% over the GLS average fair value of 46.92, with 0 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 126.37. 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.

| Lynch | 55.23 | -60% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 16.82 | -88% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |

Quality and financial health
On financial health GLW scores 7/9 (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 low at 3.8 out of 10, which says the ten-year record of revenue, earnings, margins and returns on capital has been inconsistent - growth and shocks rather than steady compounding.
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 2.0%.
The dividend yield is 0.81% with a payout ratio of 52% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from Optical communications products 46%, Electronics glass and advanced optics p… 27%, Automotive products 11% (quarter Q2 FY2026).
Institutional ownership scores 9/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 7 / 9 | ROIC | 7.2% |
|---|---|---|---|
| GLS Moat | 3.8 / 10 | ROE | 13.5% |
| Debt / equity | 0.87 | ROA | 5.2% |
| Free-cash-flow yield | 2.0% | Payout ratio | 52% |
| Institutions | 9 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 61: Fair
GLW scores 61 out of 100 on the Wheel Score (Fair band, 50-64): a usable but unremarkable fit for the wheel strategy. The parts: Value 0/25, Health 16/20, Moat 6/15, Premium 20/20, Stability 20/20. Value (0/25) is where the points are missing.
Implied volatility is 62% on the near-the-money contracts 20-60 days out - above the 60% ceiling of the sweet spot. Premiums are large, but the Wheel Score tapers the Premium points (20 of 20) because volatility this high usually comes with a reason. The option chain is deep: 418,563 contracts of open interest across all expiries, which means tight fills at most strikes.
Volume runs at 11.2M shares a day on a market cap of $119.2B, with a beta of 1.12; the Stability part of the Wheel Score gives that 20 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 0 / 25 | -195% margin of safety | |
| Health | 16 / 20 | Piotroski 7/9 | |
| Moat | 6 / 15 | moat 3.8/10 | |
| Premium | 20 / 20 | implied volatility 62% | |
| Stability | 20 / 20 | 11.2M shares/day, $119.2B cap, beta 1.12 |

Upcoming events
Corning Inc reports earnings on 27 Oct 2026 (before the open) - inside the 14-day window the Sunday Scan avoids, because a put sold now would carry the report's gap risk. The shares go ex-dividend on 13 Nov 2026 (0.2800 per share), so a covered call sold before then carries a small early-assignment risk around that date.
