- Solid quality (61/100) at a price below fair value, the discount is the argument here, not the business quality.
- A fairly wide model range (46.28 TWD to 103.46 TWD) leaves room in how you read the outcome.

Analysis
Sun Max Tech Limited (6591) currently trades at 44.90 TWD, while our model-based Fair Value estimate is 70.40 TWD, implying the stock looks roughly 56.8% undervalued today. The Quality Score stands at 61/100 (solid 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, Sun Max Tech Limited generated revenue of 1.6B TWD at a net margin of 10.7%. Revenue declined 25.5% year over year. It earns a return on equity of 8.5%. The balance sheet holds a net cash position of 410M TWD. Fundamentals as of Jul 21, 2026
Our scenario range runs from 46.28 TWD (bear case) to 103.46 TWD (bull case); at 44.90 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 56% below its 52-week high, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -67% fair-value upside, at 57%, 6591 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 25 models by family
Widest divergence: Multiples (93.64 TWD) versus Growth DCF (20.09 TWD). Highest evidence: Growth DCF (80).
