ChipMOS TECHNOLOGIES Inc. (IMOS): fair value, margin of safety and Wheel Score
Technology · Semiconductors · Taiwan · ADR · Blend
Is IMOS undervalued?
At 65.14 (close of 16 Oct 2026), IMOS trades 57% below the GLS average fair value of 152.05. That average comes from 8 models run on the latest filings, and 3 of them land above the current price. Margins of safety over 30% are the exception rather than the rule across the ~7,400 stocks we value each night, so the number earns ChipMOS TECHNOLOGIES Inc. the full Value points in the Wheel Score - and a closer look at what the market is pricing in.
The 8 models disagree widely: GLS Growth gives 5.81 while 10 Cap gives 567.49. 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.

|---|---|---|---|
| DCF | 45.44 | -30% | Present value of the projected free cash flows, discounted at the cost of capital |

| Lynch | 49.58 | -24% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |

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 2.8 out of 10, which says the ten-year record of revenue, earnings, margins and returns on capital has been inconsistent - growth and shocks rather than steady compounding.
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 1.17% 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 | 2.8 / 10 | ROE | 2.1% |
| Debt / equity | 0.68 | ROA | 1.1% |
| Free-cash-flow yield | -0.7% | Payout ratio | 39% |
| Institutions | 5 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 74: Good
IMOS scores 74 out of 100 on the Wheel Score (Good band, 65-79). The score blends the margin of safety (Value, 25/25), Piotroski health (18/20), the GLS moat (4/15), the option premium on offer (18/20) and how easily the stock trades (9/20). Moat (4/15) is the part holding the score back.
Implied volatility is 67% on the near-the-money contracts 20-60 days out - above the 60% ceiling of the sweet spot. Premiums are large, but the Wheel Score tapers the Premium points (18 of 20) because volatility this high usually comes with a reason. Chain open interest is thin - 1,273 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 93k shares a day on a market cap of $2.3B, with a beta of 1.25 - 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 gives that 9 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 25 / 25 | 57% margin of safety | |
| Health | 18 / 20 | Piotroski 8/9 | |
| Moat | 4 / 15 | moat 2.8/10 | |
| Premium | 18 / 20 | implied volatility 67% | |
| Stability | 9 / 20 | 93k shares/day, $2.3B cap, beta 1.25 |
