Analysis
Gallant Micro. Machining Co (6640) currently trades at 918.00 TWD, while our model-based Fair Value estimate is 212.15 TWD, implying the stock looks roughly 76.9% overvalued today. The Quality Score stands at 47/100 (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, Gallant Micro. Machining Co generated revenue of 3.1B TWD at a net margin of 14.9%. Revenue grew 93.0% year over year. It earns a return on equity of 19.0%. Net debt stands at 726M TWD. Fundamentals as of Jul 21, 2026
Our scenario range runs from 159.11 TWD (bear case) to 265.19 TWD (bull case); at 918.00 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 51% below its 52-week high and 77% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -75% fair-value upside, at -77%, 6640 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 15 models by family
Widest divergence: Growth Earnings (324.83 TWD) versus Asset-Based (57.35 TWD). Highest evidence: Residual Income (76).
