Analysis
TAI-TECH Advanced Electronics Co (3357) currently trades at 207.00 TWD, while our model-based Fair Value estimate is 148.99 TWD, implying the stock looks roughly 28.0% overvalued today. The Quality Score stands at 57/100 (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, TAI-TECH Advanced Electronics Co generated revenue of 6.8B TWD at a net margin of 16.4%. Revenue grew 11.3% year over year. It earns a return on equity of 12.6%. Net debt stands at 416M TWD. Fundamentals as of Jul 23, 2026
Our scenario range runs from 80.70 TWD (bear case) to 205.71 TWD (bull case); at 207.00 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 37% below its 52-week high and 128% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -73% fair-value upside, at -28%, 3357 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: Growth Earnings (209.34 TWD) versus Growth DCF (48.13 TWD). Highest evidence: Growth DCF (80).
