Analysis
GSD Technologies Co (6641) currently trades at 18.20 TWD, while our model-based Fair Value estimate is 9.67 TWD, implying the stock looks roughly 46.9% overvalued today. The Quality Score stands at 63/100 (solid quality), in the Industrials 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, GSD Technologies Co generated revenue of 1.7B TWD at a net margin of 1.0%. Revenue declined 6.1% year over year. It earns a return on equity of 0.6%. The balance sheet holds a net cash position of 223M TWD. Fundamentals as of Jul 23, 2026
Our scenario range runs from 8.69 TWD (bear case) to 12.09 TWD (bull case); at 18.20 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 36% below its 52-week high and 3% above its 52-week low, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -48% fair-value upside, at -47%, 6641 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.
