Alpha and Omega Semiconductor Limited (AOSL): fair value, margin of safety and Wheel Score
Ticker symbol AOSL · Technology · Semiconductors · United States · Speculative
Is AOSL undervalued?
Alpha and Omega Semiconductor Limited (AOSL) closed at 21.17 on 5 Nov 2026, close to the GLS average fair value of 19.70 (7.5% above fair value). 0 of the 1 models that produced a number sit above the price, 1 below - the market and our models roughly agree. With little margin of safety either way, the case for or against the stock rests on the quality numbers and the option premium rather than on price.
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 - it is losing money or its Piotroski health score is 3 or lower - 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 | 19.70 | -7% | 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 |
| Zombie (liquidation) | 8.98 | -58% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 45.50 | +115% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Alpha and Omega Semiconductor Limited scores only 4 of 9 on the Piotroski F-score, which fails the "Piotroski 6 or more" Wheel Trade Filter. 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 2.4/10 is a weak reading: the accounts do not show returns and margins that competitors have been unable to wear down, 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 | 4 / 9 | ROIC | -5.1% |
|---|---|---|---|
| GLS Moat | 2.4 / 10 | ROE | -5.3% |
| Debt / equity | 0.04 | ROA | -4.4% |
| Free-cash-flow yield | -2.6% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 2 · 5 / 10 |
Wheel Score 17: Weak
With a Wheel Score of 17 Alpha and Omega Semiconductor Limited sits in the Weak band. It fails filter 2, a real business, not a gamble - speculative (a loss, or a weak Piotroski score); and filter 3, below fair value - trades 7% above our fair value; and filter 4, financially healthy - Piotroski 4/9 (under 6); and filter 5, can repay its debt - debt with no positive cash flow to repay it; and filter 6, no serious red flags - Red Flags score 55 (under 60); and filter 7, a premium worth selling - implied volatility 91% (over 80%); and filter 8, big enough - market cap $642M (under $1.0B); Value (weak) is its weakest part.
Implied volatility is 91%, above the 80% ceiling of the Wheel Trade Filter on premium. The premium looks generous, but moves of that size can blow through any strike. Chain open interest is 7,755 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 533k shares a day on a market cap of $642M, with a beta of 2.70 - 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 | Fails | speculative (a loss, or a weak Piotroski score) |
| 3 | Below fair value | Fails | trades 7% above our fair value |
| 4 | Financially healthy | Fails | Piotroski 4/9 (under 6) |
| 5 | Can repay its debt | Fails | debt with no positive cash flow to repay it |
| 6 | No serious red flags | Fails | Red Flags score 55 (under 60) |
| 7 | A premium worth selling | Fails | implied volatility 91% (over 80%) |
| 8 | Big enough | Fails | market cap $642M (under $1.0B) |
| 9 | Not a penny stock | Passes | Share price $5 or more |
| How it ranks | Rating | From | |
|---|---|---|---|
| Value | Weak | 7% above fair value | |
| Premium | Fair | implied volatility 91% | |
| Moat | Weak | moat 2.4/10 | |
| Health | Fair | Piotroski 4/9 | |
| Red Flags | Weak | Red Flags score 55/100 | |
| Option trading | Fair | 1,331 contracts a day, 7,755 open interest | |
