- The price sits above even our optimistic bull case (39.19 TWD). The favourable scenario is already priced in.
- Solid but not exceptional quality (56/100) and above fair value, neither a clear bargain nor a standout compounder.

Analysis
Zyxel Group (3704) currently trades at 45.85 TWD, while our model-based Fair Value estimate is 30.95 TWD, implying the stock looks roughly 32.5% overvalued today. The Quality Score stands at 56/100 (solid 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: high).
Over the trailing twelve months, Zyxel Group generated revenue of 24.6B TWD at a net margin of 1.9%. Revenue declined 10.3% year over year. It earns a return on equity of 4.1%. Net debt stands at 568M TWD. Fundamentals as of Jul 21, 2026
Our scenario range runs from 20.78 TWD (bear case) to 39.19 TWD (bull case); at 45.85 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 8% below its 52-week high and 78% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -61% fair-value upside, at -33%, 3704 screens cheaper 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 25 models by family
Widest divergence: Multiples (31.35 TWD) versus Dividend Discount (4.31 TWD). Highest evidence: Growth DCF (80).
