G-TECH Optoelectronics Corporation (3149) Fair Value & Analysis
Technology · TW · Market cap 17.5B TWD
Fair value as of: Jul 23, 2026
From 3 valuation models · updated 18 days ago
Share price −26.5% over the past month.
Below-average quality, and screening another 76% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (24.20 TWD). The favourable scenario is already priced in.
- Weak quality (18/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The model range is unusually wide (8.30 TWD to 24.20 TWD). The outcome hinges heavily on assumptions, so read the point estimate with caution.
- 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 16.50 TWD – 104.50 TWD · fair‑value band 8.30 TWD – 24.20 TWD · the 62.80 TWD price screens above the 15.21 TWD fair value. Dashed = 300-day average. As of Jul 23, 2026.
Analysis
G-TECH Optoelectronics Corporation (3149) currently trades at 62.80 TWD, while our model-based Fair Value estimate is 15.21 TWD, implying the stock looks roughly 75.8% overvalued today. The Quality Score stands at 18/100 (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).
Over the trailing twelve months, G-TECH Optoelectronics Corporation generated revenue of 2.4B TWD at a net margin of -22.6%. Revenue grew 25.4% year over year. It earns a return on equity of -25.3%. Net debt stands at 890M TWD. Fundamentals as of Jul 23, 2026
Our scenario range runs from 8.30 TWD (bear case) to 24.20 TWD (bull case); at 62.80 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 35% below its 52-week high and 115% 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 -76%, 3149 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
Widest divergence: Dividend Discount (15.34 TWD) versus Asset-Based (7.11 TWD). Highest evidence: Gordon GGM (70).
