Analysis
Chengdu Shengbang Seals Co (301233) currently trades at ¥36.10, while our model-based Fair Value estimate is ¥26.87, implying the stock looks roughly 25.6% overvalued today. The Quality Score stands at 63/100 (solid quality), in the Basic Materials 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, Chengdu Shengbang Seals Co generated revenue of 432M CNY at a net margin of 18.8%. Revenue declined 8.1% year over year. It earns a return on equity of 8.3%. The stock trades on a trailing P/E of 32.7. Fundamentals as of Jul 9, 2026
Our scenario range runs from ¥17.29 (bear case) to ¥35.97 (bull case); at ¥36.10, 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 48% below its 52-week high, currently below its 200-day average. For context, the median of 10 Basic Materials peers we cover trades at -58% fair-value upside, at -26%, 301233 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: Multiples (¥27.66) versus Asset-Based (¥12.82). Highest evidence: Residual Income (76).
