Formosa Electronic Industries Inc (8171) Fair Value & Analysis
Technology · TW · Market cap 2.3B TWD
Fair value as of: Jul 22, 2026
From 3 valuation models · updated 20 days ago
Share price −1.5% over the past month.
Below-average quality, and screening another 80% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (4.72 TWD). The favourable scenario is already priced in.
- Weak quality (9/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.

How to read this chart
60‑month range 19.25 TWD – 66.76 TWD · fair‑value band 3.75 TWD – 4.72 TWD · the 20.20 TWD price screens above the 4.13 TWD fair value. Dashed = 300-day average. As of Jul 22, 2026.
Analysis
Formosa Electronic Industries Inc (8171) currently trades at 20.20 TWD, while our model-based Fair Value estimate is 4.13 TWD, implying the stock looks roughly 79.6% overvalued today. The Quality Score stands at 9/100 (below-average quality), in the Technology sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: low).
Trailing-twelve-month revenue stands at 315M TWD. Revenue grew 2.3% year over year. It earns a return on equity of -29.0%. Net debt stands at 55.1M TWD. Fundamentals as of Jul 22, 2026
Our scenario range runs from 3.75 TWD (bear case) to 4.72 TWD (bull case); at 20.20 TWD, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 39% below its 52-week high, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -73% fair-value upside, at -80%, 8171 screens richer than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
All 3 models by family
