What matters now
- The price sits above even our optimistic bull case (4.55 TWD). The favourable scenario is already priced in.

Analysis
Edison Opto Corporation (3591) currently trades at 21.70 TWD, while our model-based Fair Value estimate is 4.39 TWD, implying the stock looks roughly 79.8% overvalued today. The Quality Score stands at 44/100 (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: medium).
Over the trailing twelve months, Edison Opto Corporation generated revenue of 2.3B TWD at a net margin of -1.9%. Revenue grew 1.5% year over year. It earns a return on equity of -1.2%. The balance sheet holds a net cash position of 532M TWD. Fundamentals as of Jul 23, 2026
Our scenario range runs from 4.29 TWD (bear case) to 4.55 TWD (bull case); at 21.70 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 27% below its 52-week high and 33% 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 -80%, 3591 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: Asset-Based (13.23 TWD) versus Earnings-Based (4.30 TWD). Highest evidence: Growth DCF (80).
