Analysis
Sea Sonic Electronics Co (6203) currently trades at 61.00 TWD, while our model-based Fair Value estimate is 109.62 TWD, implying the stock looks roughly 79.7% undervalued today. The Quality Score stands at 86/100 (high quality), in the Technology sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: high), always confirm before acting.
Over the trailing twelve months, Sea Sonic Electronics Co generated revenue of 2.6B TWD at a net margin of 15.8%. Revenue declined 21.0% year over year. It earns a return on equity of 13.2%. The balance sheet holds a net cash position of 1.0B TWD. Fundamentals as of Jul 21, 2026
Our scenario range runs from 82.64 TWD (bear case) to 133.84 TWD (bull case); at 61.00 TWD, the current price sits below 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 30% below its 52-week high and 1% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -73% fair-value upside, at 80%, 6203 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 24 models by family
Widest divergence: DCF Models (129.66 TWD) versus Asset-Based (25.29 TWD). Highest evidence: Growth DCF (80).
