Amkor Technology, Inc. (AMKR): fair value, margin of safety and Wheel Score
Ticker symbol AMKR · Technology · Semiconductors · United States · Blend
Is AMKR undervalued?
At 35.66 (close of 5 Nov 2026), AMKR trades 10% over the GLS average fair value of 32.40. 3 of the 9 models land above the price and 6 below. A negative margin of safety fails the "below fair value" Wheel Trade Filter - the models see no discount, which does not make the business a poor one, only the price a full one.
There is a wide gap between DDM (4.92) and 10 Cap (73.76). 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, neither cheapness nor growth clearly wins for AMKR, so the nightly engine files it under Blend (value score 45, growth score 32, out of 100).

Quality and financial health
Amkor Technology, 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 AMKR scores 5.9/10 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 moderate - ROIC 6.2%, ROE 8.4%, ROA 4.6% - with debt at 0.35 times equity and a free-cash-flow yield of 6.0%.
The dividend yield is 0.94% with a payout ratio of 13% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from Advanced Products 82%, Mainstream Products 18% (quarter Q3 FY2026).
Institutional ownership scores 6/10, insider activity 6/10 and Congressional trading 5/10 on the GLS smart-money scales; the last recorded insider buy was on 22 Sep 2026.
| Piotroski F-score | 6 / 9 | ROIC | 6.2% |
|---|---|---|---|
| GLS Moat | 5.9 / 10 | ROE | 8.4% |
| Debt / equity | 0.35 | ROA | 4.6% |
| Free-cash-flow yield | 6.0% | Payout ratio | 13% |
| Institutions | 6 / 10 | Insiders · Congress | 6 · 5 / 10 |
Wheel Score 35: Weak
With a Wheel Score of 35 Amkor Technology, Inc. sits in the Weak band. It fails filter 3, below fair value - trades 10% above our fair value; Value (weak) is its weakest part.
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: 72,386 contracts of open interest across all expiries, which means tight fills at most strikes.
Volume runs at 4.3M shares a day on a market cap of $8.8B, with a beta of 2.40 - 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 weak.
| 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 10% 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 | 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 | Weak | 10% above fair value | |
| Premium | Good | implied volatility 70% | |
| Moat | Fair | moat 5.9/10 | |
| Health | Good | Piotroski 6/9 | |
| Red Flags | Fair | Red Flags score 75/100 | |
| Option trading | Strong | 7,016 contracts a day, 72,386 open interest | |
| Stability | Weak | beta 2.40, $8.8B company |
