Analysis
Keystone Microtech Corporation (6683) currently trades at 1,120 TWD, while our model-based Fair Value estimate is 304.13 TWD, implying the stock looks roughly 72.9% overvalued today. The Quality Score stands at 73/100 (solid 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, Keystone Microtech Corporation generated revenue of 2.3B TWD at a net margin of 20.7%. Revenue grew 46.3% year over year. It earns a return on equity of 17.5%. The balance sheet holds a net cash position of 1.3B TWD. Fundamentals as of Jul 19, 2026
Our scenario range runs from 228.10 TWD (bear case) to 380.16 TWD (bull case); at 1,120 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 56% below its 52-week high and 252% 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 -73%, 6683 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 26 models by family
Widest divergence: DCF Models (528.64 TWD) versus Asset-Based (65.99 TWD). Highest evidence: Residual Income (76).
