ChipMOS TECHNOLOGIES Inc. (IMOS): fair value, margin of safety and Wheel Score
Ticker symbol IMOS · Technology · Semiconductors · Taiwan · ADR · Blend
IMOS is an American depositary share (ADR): the US listing of ChipMOS TECHNOLOGIES Inc., whose own shares trade on its home exchange. It trades in dollars during US hours; currency moves and the home country's rules also affect it, and the depositary bank charges a small yearly fee.
Is IMOS undervalued?
At 51.19 (close of 5 Nov 2026), IMOS trades 27% over the GLS average fair value of 40.18. 2 of the 8 models land above the price and 6 below. A negative margin of safety fails the "below fair value" Wheel Trade Filter - the models see no discount, which does not make the business a poor one, only the price a full one.
The 8 models disagree widely: GLS Growth gives 6.33 while Graham Growth gives 123.75. 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 IMOS, so the nightly engine files it under Blend (value score 31, growth score 31, out of 100).
Nine valuation models for IMOS
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 | 44.86 | -12% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 31.84 | -38% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 123.75 | +142% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 54.09 | +6% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 6.33 | -88% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 25.39 | -50% | 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 | 11.11 | -78% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | 24.04 | -53% | Earnings power value: current EPS capitalised at 9% with no growth |
| Zombie (liquidation) | 3.30 | -94% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 0.0000 | -100% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
On financial health IMOS scores 8/9 (Piotroski): most of the nine tests - positive earnings and cash flow, falling debt, rising margins and turnover - are passed, which is the kind of balance sheet a wheel trader is happy to be assigned. The GLS Moat score is low at 4.6 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 1.2%, ROE 2.1%, ROA 1.1% - with debt at 0.68 times equity and negative free cash flow.
The dividend yield is 1.47% with a payout ratio of 39% - a small yield that leaves most of the earnings in the business.
Institutional ownership scores 5/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 8 / 9 | ROIC | 1.2% |
|---|---|---|---|
| GLS Moat | 4.6 / 10 | ROE | 2.1% |
| Debt / equity | 0.68 | ROA | 1.1% |
| Free-cash-flow yield | -1.0% | Payout ratio | 39% |
| Institutions | 5 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 33: Weak
IMOS scores 33 out of 100 on the Wheel Score, in the Weak band (under 50): it fails filter 1, options that actually trade - options too quiet (263 open interest, 44 a day); and filter 3, below fair value - trades 27% above our fair value, and the parts are thin too - value weak, premium good, moat fair, health strong, red flags strong, option trading weak, 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 77% on the near-the-money contracts 20-60 days out - above the 60% top of the sweet spot. It still passes the 25-80% filter, but the Wheel Score rewards it less because volatility this high usually comes with a reason. Chain open interest is thin - 263 contracts across every expiry - so fills at a fair price are not guaranteed; a 30-45-day put may not exist at a usable strike.
Volume runs at 91k shares a day on a market cap of $1.8B, with a beta of 1.35 - 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 | Fails | options too quiet (263 open interest, 44 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 | Fails | trades 27% above our fair value |
| 4 | Financially healthy | Passes | Piotroski F-score 6 or more out of 9 (a company with no score on file passes) |
| 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 | Passes | Implied volatility 25-80% (enough premium, not a lottery ticket) |
| 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 | 27% above fair value | |
| Premium | Good | implied volatility 77% | |
| Moat | Fair | moat 4.6/10 | |
| Health | Strong | Piotroski 8/9 | |
| Red Flags | Strong | Red Flags score 100/100 | |
| Option trading | Weak | 44 contracts a day, 263 open interest | |
| Stability | Fair | beta 1.35, $1.8B company |
