Analysis
Giantec Semiconductor Corporation (688123) currently trades at ¥128.99, while our model-based Fair Value estimate is ¥39.47, implying the stock looks roughly 69.4% overvalued today. The Quality Score stands at 78/100 (high 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, Giantec Semiconductor Corporation generated revenue of 1.2B CNY at a net margin of 23.8%. Revenue grew 7.3% year over year. It earns a return on equity of 11.9%. The balance sheet holds a net cash position of 940M CNY. Fundamentals as of Aug 12, 2026
Our scenario range runs from ¥31.08 (bear case) to ¥48.53 (bull case); at ¥128.99, 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 33% below its 52-week high and 78% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -67% fair-value upside, at -69%, 688123 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 26 models by family
Widest divergence: DCF Models (¥61.06) versus Dividend Discount (¥4.81). Highest evidence: Residual Income (76).
