Goldkey Technology Corporation (3135) Fair Value & Analysis
Technology · TW · Market cap 13.5B TWD
Fair value as of: Jul 23, 2026
From 17 valuation models · updated 18 days ago
Share price −2.0% over the past month.
Below-average quality, and screening another 52% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (134.66 TWD). The favourable scenario is already priced in.
- Weak quality (40/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The model range is unusually wide (30.80 TWD to 134.66 TWD). The outcome hinges heavily on assumptions, so read the point estimate with caution.

Analysis
Goldkey Technology Corporation (3135) currently trades at 168.00 TWD, while our model-based Fair Value estimate is 80.21 TWD, implying the stock looks roughly 52.3% overvalued today. The Quality Score stands at 40/100 (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: high).
Over the trailing twelve months, Goldkey Technology Corporation generated revenue of 7.7B TWD at a net margin of 5.8%. Revenue grew 51.5% year over year. It earns a return on equity of 26.9%. Net debt stands at 2.6B TWD. Fundamentals as of Jul 23, 2026
Our scenario range runs from 30.80 TWD (bear case) to 134.66 TWD (bull case); at 168.00 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 37% below its 52-week high, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -67% fair-value upside, at -52%, 3135 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 17 models by family
Widest divergence: Growth Earnings (174.82 TWD) versus Asset-Based (15.86 TWD). Highest evidence: Residual Income (76).
