Silicon Laboratories Inc. (SLAB): fair value, margin of safety and Wheel Score
Ticker symbol SLAB · Technology · Semiconductors · United States · Speculative
Is SLAB undervalued?
At 222.00 (close of 5 Nov 2026), SLAB trades 2962% over the GLS average fair value of 7.25, with 0 of 2 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.
Only 2 of the nine models produced a value (DCF, 10 Cap); the others need a dividend, positive free cash flow or positive book value the company does not have yet, so the average rests on a narrow base.
The nightly engine files SLAB 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 SLAB
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 | 6.62 | -97% | 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 | 7.88 | -96% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| 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) | 14.96 | -93% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 183.40 | -17% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is average - SLAB passes 5 of the nine Piotroski tests, which falls one point short of the "Piotroski 6 or more" Wheel Trade Filter. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is low at 3.8 out of 10: returns on capital, margins or the balance sheet have not shown a lasting edge yet - often a young company, a thin-margin business or one that has only recently turned profitable.
Returns on capital are thin or negative - ROIC -5.9%, ROE -5.9%, ROA -5.1% - with debt at 0.00 times equity and negative free cash flow.
Silicon Laboratories Inc. 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 Industrial & Commercial 59%, Home & Life 41% (quarter Q2 FY2026).
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 | -5.9% |
|---|---|---|---|
| GLS Moat | 3.8 / 10 | ROE | -5.9% |
| Debt / equity | 0.00 | ROA | -5.1% |
| Free-cash-flow yield | -0.1% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 23: Weak
SLAB scores 23 out of 100 on the Wheel Score, in the Weak band (under 50): 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 2962% above our fair value; and filter 4, financially healthy - Piotroski 5/9 (under 6); and filter 7, a premium worth selling - implied volatility 21% (under 25%), and the parts are thin too - value weak, premium weak, moat fair, health fair, red flags good, option trading fair, stability fair. The score is not a judgement on the company; it says the price, quality and premium do not line up for selling puts on it today.
Implied volatility on the near-the-money contracts is 21%, below the 25% the Wheel Trade Filter on premium asks for: a put pays too little to be worth selling. Chain open interest is 18,242 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 427k shares a day on a market cap of $7.4B, with a beta of 1.21 - 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 | Fails | speculative (a loss, or a weak Piotroski score) |
| 3 | Below fair value | Fails | trades 2962% 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 21% (under 25%) |
| 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 | 2962% above fair value | |
| Premium | Weak | implied volatility 21% | |
| Moat | Fair | moat 3.8/10 | |
| Health | Fair | Piotroski 5/9 | |
| Red Flags | Good | Red Flags score 85/100 | |
| Option trading | Fair | 922 contracts a day, 18,242 open interest | |
| Stability | Fair | beta 1.21, $7.4B company |
