Analysis
Grand-Tek Technology Co (3684) currently trades at 52.90 TWD, while our model-based Fair Value estimate is 69.25 TWD, implying the stock looks roughly 30.9% undervalued today. The Quality Score stands at 71/100 (solid quality), in the Technology sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: high), always confirm before acting.
Over the trailing twelve months, Grand-Tek Technology Co generated revenue of 1.2B TWD at a net margin of 9.3%. Revenue grew 12.2% year over year. It earns a return on equity of 15.1%. Net debt stands at 50.1M TWD. Fundamentals as of Jul 23, 2026
Our scenario range runs from 51.79 TWD (bear case) to 86.57 TWD (bull case); at 52.90 TWD, the current price sits within 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 29% below its 52-week high and 30% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -73% fair-value upside, at 31%, 3684 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 26 models by family
Widest divergence: DCF Models (95.95 TWD) versus Asset-Based (15.92 TWD). Highest evidence: Growth DCF (80).
