Analysis
Aethertek technology co., Ltd (3219) currently trades at 71.40 TWD, while our model-based Fair Value estimate is 31.72 TWD, implying the stock looks roughly 55.6% overvalued today. The Quality Score stands at 65/100 (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: medium).
Over the trailing twelve months, Aethertek technology co., Ltd generated revenue of 1.9B TWD at a net margin of 7.9%. Revenue grew 53.3% year over year. It earns a return on equity of 9.9%. The balance sheet holds a net cash position of 651M TWD. Fundamentals as of Jul 23, 2026
Our scenario range runs from 23.79 TWD (bear case) to 39.65 TWD (bull case); at 71.40 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 66% 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 -56%, 3219 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.
