Below-average quality, and screening another 40% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (131.26 TWD). The favourable scenario is already priced in.
- Weak quality (36/100) and above fair value at the same time, the margin of safety is missing on both counts.
- A fairly wide model range (70.68 TWD to 131.26 TWD) leaves room in how you read the outcome.

Analysis
Sino-American Silicon Products Inc (5483) currently trades at 168.50 TWD, while our model-based Fair Value estimate is 100.97 TWD, implying the stock looks roughly 40.1% overvalued today. The Quality Score stands at 36/100 (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, Sino-American Silicon Products Inc generated revenue of 78.2B TWD at a net margin of 5.8%. It earns a return on equity of 8.7%. Net debt stands at 53.4B TWD. The stock trades on a trailing P/E of 22.8. Fundamentals as of Jul 19, 2026
Our scenario range runs from 70.68 TWD (bear case) to 131.26 TWD (bull case); at 168.50 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 6% below its 52-week high and 103% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -75% fair-value upside, at -40%, 5483 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 16 models by family
Widest divergence: Dividend Discount (203.86 TWD) versus Earnings-Based (53.78 TWD). Highest evidence: Residual Income (76).
