Alpha and Omega Semiconductor Limited (AOSL): fair value, margin of safety and Wheel Score
Technology · Semiconductors · United States · Speculative / Distressed
Is AOSL undervalued?
Alpha and Omega Semiconductor Limited (AOSL) closed at 23.34 on 16 Oct 2026, 19% above the GLS average fair value of 19.58. Only 0 of the 1 models that produced a number value the shares above the current price. The margin of safety is negative, so the stock fails the "below fair value" rule of the Sunday Scan; a premium of this size is common for companies whose growth the models are conservative about.
The average is built from just 1 models (DCF) - the rest returned nothing because an input they need (dividends, free cash flow, book value) is zero or negative - so treat it with more caution than usual.
The nightly engine files AOSL under Speculative / Distressed - negative earnings or a Piotroski score of 3 or less - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.
Nine valuation models for AOSL
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 | 19.58 | -16% | 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 | - | - | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10%; no value tonight |
| Payback Time | - | - | Eight years of compounded free cash flow: the price at which the business pays for itself; no value tonight |
| DDM | - | - | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend; no value tonight |
| EPV | - | - | Earnings power value: current EPS capitalised at 9% with no growth; no value tonight |

Quality and financial health
Alpha and Omega Semiconductor Limited scores only 2 of 9 on the Piotroski F-score, which fails the Sunday Scan's "6 or more" rule. A reading this low means several of the basic tests - positive earnings, positive operating cash flow, falling debt, no new share issuance - are not met. A GLS Moat score of 0.7/10 is a weak reading: the ten-year history the score grades (revenue, EPS, book value, margins, cash flow, share count, ROIC) has not been steady, so the Moat part of the Wheel Score contributes little.
Returns on capital are thin or negative - ROIC -5.1%, ROE -5.3%, ROA -4.4% - with debt at 0.04 times equity and negative free cash flow.
Alpha and Omega Semiconductor Limited pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain. Revenue comes mainly from Power Discrete 67%, Power IC 33%, Packaging and testing services 1% (quarter Q4 FY2026).
Institutional ownership scores 10/10, insider activity 2/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 2 / 9 | ROIC | -5.1% |
|---|---|---|---|
| GLS Moat | 0.7 / 10 | ROE | -5.3% |
| Debt / equity | 0.04 | ROA | -4.4% |
| Free-cash-flow yield | -2.4% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 2 · 5 / 10 |
Wheel Score 31: Weak
With a Wheel Score of 31 Alpha and Omega Semiconductor Limited sits in the Weak band. The parts - Value 5/25, Health 4/20, Moat 1/15, Premium 14/20, Stability 8/20 - show where: Moat (1/15) scores lowest.
Implied volatility is 85% 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 (14 of 20) because volatility this high usually comes with a reason. Chain open interest is 12,859 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 660k shares a day on a market cap of $707M, with a beta of 2.64 - 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 gives that 8 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 5 / 25 | -19% margin of safety | |
| Health | 4 / 20 | Piotroski 2/9 | |
| Moat | 1 / 15 | moat 0.7/10 | |
| Premium | 14 / 20 | implied volatility 85% | |
| Stability | 8 / 20 | 660k shares/day, $707M cap, beta 2.64 |
