Analysis
STL Technology Co (4931) currently trades at 216.50 TWD, while our model-based Fair Value estimate is 62.33 TWD, implying the stock looks roughly 71.2% overvalued today. The Quality Score stands at 72/100 (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, STL Technology Co generated revenue of 2.6B TWD at a net margin of 8.1%. Revenue grew 20.5% year over year. It earns a return on equity of 16.2%. The balance sheet holds a net cash position of 321M TWD. Fundamentals as of Jul 23, 2026
Our scenario range runs from 45.79 TWD (bear case) to 77.86 TWD (bull case); at 216.50 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 25% below its 52-week high and 171% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -48% fair-value upside, at -71%, 4931 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 24 models by family
