SK hynix Inc. (SKHY): fair value, margin of safety and Wheel Score
Ticker symbol SKHY · Technology · Semiconductors · South Korea · ADR · Growth
SKHY is an American depositary share (ADR): the US listing of SK hynix Inc., whose own shares trade on its home exchange. It trades in dollars during US hours; currency moves and the home country's rules also affect it, and the depositary bank charges a small yearly fee.
Is SKHY undervalued?
At 143.07 (close of 5 Nov 2026), SKHY trades 79% below the GLS average fair value of 666.57. That average comes from 8 models run on the latest filings, and 6 of them land above the current price. Margins of safety over 30% are the exception rather than the rule across the ~7,400 stocks we value each night, so the number earns SK hynix Inc. the full Value points in the Wheel Score - and a closer look at what the market is pricing in.
There is a wide gap between DDM (3.27) and GLS Growth (1,784.30). 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, SKHY is clearly faster-growing than it is cheap, so the nightly engine files it under Growth (value score 65, growth score 88, out of 100).

| Model | Value | vs price | What it measures |
|---|---|---|---|

| Lynch | 728.64 | +409% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 1,784.30 | +1147% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |

Quality and financial health
SK hynix 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. On durability SKHY scores 6.3/10 on the GLS Moat - a middle reading; the Moat Score tab on the Quote page's Financials view shows which of the four parts hold it back.
Returns on capital are high - ROIC 29.5%, ROE 35.6%, ROA 24.4% - with debt at 0.21 times equity and a free-cash-flow yield of 10.2%.
The dividend yield is 0.16% with a payout ratio of 1% - a small yield that leaves most of the earnings in the business.
Institutional ownership scores 1/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 6 / 9 | ROIC | 29.5% |
|---|---|---|---|
| GLS Moat | 6.3 / 10 | ROE | 35.6% |
| Debt / equity | 0.21 | ROA | 24.4% |
| Free-cash-flow yield | 10.2% | Payout ratio | 1% |
| Institutions | 1 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 84: Good
With a Wheel Score of 84 - the Good band - SK hynix Inc. passes all 9 Wheel Trade Filters. How it ranks: value strong, premium strong, moat good, health good, red flags strong, option trading strong, stability fair. Stability (fair) is the part keeping it out of the Prime band.
Implied volatility is 70% 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: 646,792 contracts of open interest across all expiries, which means tight fills at most strikes.
Volume runs at 20.6M shares a day on a market cap of $1.02T, with a beta of 2.39 - 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 fair.
| 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 | 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 | 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 | 79% below fair value | |
| Premium | Strong | implied volatility 70% | |
| Moat | Good | moat 6.3/10 | |
| Health | Good | Piotroski 6/9 | |
| Red Flags | Strong | Red Flags score 92/100 | |
| Option trading | Strong | 78,062 contracts a day, 646,792 open interest | |
| Stability | Fair | beta 2.39, $1.02T company |
