Analysis
StarPower Semiconductor Ltd (603290) currently trades at ¥88.53, while our model-based Fair Value estimate is ¥30.25, implying the stock looks roughly 65.8% overvalued today. The Quality Score stands at 42/100 (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: high).
Over the trailing twelve months, StarPower Semiconductor Ltd generated revenue of 4.0B CNY at a net margin of 8.3%. Revenue declined 6.0% year over year. It earns a return on equity of 4.8%. Net debt stands at 616M CNY. Fundamentals as of Aug 10, 2026
Our scenario range runs from ¥22.05 (bear case) to ¥38.46 (bull case); at ¥88.53, 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 39% below its 52-week high and 16% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -75% fair-value upside, at -66%, 603290 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 17 models by family
Widest divergence: Growth Earnings (¥57.93) versus Economic Profit (¥13.37). Highest evidence: Residual Income (76).
