Ticker symbol SIMO · Technology · Semiconductors · Hong Kong SAR China · ADR · Blend

Is SIMO undervalued?
SIMO has a margin of safety of 79%: the stock closed at 182.54 on 5 Nov 2026 against a GLS average fair value of 862.57. 4 of the 7 valuation models that produced a number sit above the price. Our scans treat a discount this large as a strong starting point for a cash-secured put, not as a verdict - the fair value is a model output, and a wide gap can mean the models are missing something the market knows.
The 7 models disagree widely: DDM gives 30.53 while GLS Growth gives 2,282.61. A spread that wide means the average is sensitive to which methods you trust; the model table below shows where each one lands, and the Quote page lets you switch any of them off.
Ranked against every other company we cover, neither cheapness nor growth clearly wins for SIMO, so the nightly engine files it under Blend (value score 81, growth score 73, out of 100).
Nine valuation models for SIMO
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 | 162.11 | -11% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 83.63 | -54% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 2,132.72 | +1068% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 932.13 | +411% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 2,282.61 | +1150% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 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 | 30.53 | -83% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | 414.28 | +127% | Earnings power value: current EPS capitalised at 9% with no growth |

Quality and financial health
Financial health is average - SIMO 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 7.5 out of 10 - high returns on capital, steady margins and growth that held up through bad years point to a durable business.
Returns on capital are high - ROIC 14.8%, ROE 14.8%, ROA 10.0% - with debt at 0.00 times equity and negative free cash flow.
The dividend yield is 1.14% with a payout ratio of 21% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from Mobile Storage 99%, Other products 1% (fiscal year FY2025).
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 | 14.8% |
|---|---|---|---|
| GLS Moat | 7.5 / 10 | ROE | 14.8% |
| Debt / equity | 0.00 | ROA | 10.0% |
| Free-cash-flow yield | -6.6% | Payout ratio | 21% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 48: Weak
SIMO scores 48 out of 100 on the Wheel Score, in the Weak band (under 50): it fails filter 4, financially healthy - Piotroski 5/9 (under 6); and filter 7, a premium worth selling - implied volatility 85% (over 80%), and the parts are thin too - value strong, premium fair, moat good, health fair, red flags strong, 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 is 85%, 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 18,938 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 1.9M shares a day on a market cap of $6.1B, with a beta of 1.77 - 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 | Passes | Profitable over the last twelve months - not a speculative stock, fund or note |
| 3 | Below fair value | Passes | Trading below the nine-model average fair value (margin of safety above 0) |
| 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 85% (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 | |
|---|---|---|---|
| Value | Strong | 79% below fair value | |
| Premium | Fair | implied volatility 85% | |
| Moat | Good | moat 7.5/10 | |
| Health | Fair | Piotroski 5/9 | |
| Red Flags | Strong | Red Flags score 95/100 | |
| Option trading | Fair | 2,801 contracts a day, 18,938 open interest | |
| Stability | Fair | beta 1.77, $6.1B company |
