Analysis
Fulltech Fiber Glass Corp (1815) currently trades at 85.90 TWD, while our model-based Fair Value estimate is 21.14 TWD, implying the stock looks roughly 75.4% overvalued today. The Quality Score stands at 36/100 (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, Fulltech Fiber Glass Corp generated revenue of 6.5B TWD at a net margin of 17.7%. Revenue grew 36.1% year over year. It earns a return on equity of 10.8%. Net debt stands at 2.2B TWD. Fundamentals as of Jul 17, 2026
Our scenario range runs from 15.85 TWD (bear case) to 27.21 TWD (bull case); at 85.90 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 34% below its 52-week high and 154% 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 -75%, 1815 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 16 models by family
Widest divergence: Growth Earnings (35.63 TWD) versus Dividend Discount (1.21 TWD). Highest evidence: Residual Income (76).
