Analysis
Tontek Design Technology Ltd (5487) currently trades at 29.25 TWD, while our model-based Fair Value estimate is 17.84 TWD, implying the stock looks roughly 39.0% overvalued today. The Quality Score stands at 60/100 (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: medium).
Over the trailing twelve months, Tontek Design Technology Ltd generated revenue of 157M TWD at a net margin of -9.0%. Revenue declined 15.6% year over year. It earns a return on equity of -2.7%. The balance sheet holds a net cash position of 243M TWD. Fundamentals as of Jul 23, 2026
Our scenario range runs from 15.50 TWD (bear case) to 20.18 TWD (bull case); at 29.25 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 14% below its 52-week high and 15% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -73% fair-value upside, at -39%, 5487 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 9 models by family
Widest divergence: Multiples (17.89 TWD) versus Dividend Discount (11.25 TWD). Highest evidence: Growth DCF (72).
