Ambarella, Inc. (AMBA): fair value, margin of safety and Wheel Score
Ticker symbol AMBA · Technology · Semiconductors · United States · Speculative
Is AMBA undervalued?
At 60.92 (close of 5 Nov 2026), AMBA trades 702% over the GLS average fair value of 7.60, with 0 of 1 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 average is built from just 1 models (10 Cap) - 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 AMBA 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 AMBA
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.

Quality and financial health
Ambarella, Inc. scores 5 of 9 on the Piotroski F-score: a middling result that falls one point short of 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. A GLS Moat score of 3.7/10 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 -12.5%, ROE -12.8%, ROA -9.5% - with debt at 0.02 times equity and a free-cash-flow yield of 0.3%.
Ambarella, Inc. pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain.
Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 5 / 9 | ROIC | -12.5% |
|---|---|---|---|
| GLS Moat | 3.7 / 10 | ROE | -12.8% |
| Debt / equity | 0.02 | ROA | -9.5% |
| Free-cash-flow yield | 0.3% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 24: Weak
With a Wheel Score of 24 Ambarella, Inc. 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 702% above our fair value; and filter 4, financially healthy - Piotroski 5/9 (under 6); and filter 7, a premium worth selling - implied volatility 89% (over 80%); Value (weak) is its weakest part.
Implied volatility is 89%, 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 40,112 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 960k shares a day on a market cap of $2.7B, with a beta of 2.09 - 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 702% above our fair value |
| 4 | Financially healthy | Fails | Piotroski 5/9 (under 6) |
| 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 | Fails | implied volatility 89% (over 80%) |
| 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 | |

| Health | Fair | Piotroski 5/9 | |
| Red Flags | Weak | Red Flags score 60/100 | |
| Option trading | Good | 4,646 contracts a day, 40,112 open interest | |
