Analysis
Tianjin Ruixin Technology Co (300828) currently trades at ¥15.63, while our model-based Fair Value estimate is ¥4.46, implying the stock looks roughly 71.5% overvalued today. The Quality Score stands at 59/100 (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, Tianjin Ruixin Technology Co generated revenue of 609M CNY at a net margin of 4.5%. Revenue grew 10.7% year over year. It earns a return on equity of 3.5%. The balance sheet holds a net cash position of 42.2M CNY. Fundamentals as of Aug 13, 2026
Our scenario range runs from ¥3.35 (bear case) to ¥5.57 (bull case); at ¥15.63, 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 50% below its 52-week high and 5% above its 52-week low, currently below its 200-day average. For context, the median of 10 Basic Materials peers we cover trades at 10% fair-value upside, at -71%, 300828 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 24 models by family
Widest divergence: DCF Models (¥3.67) versus Earnings-Based (¥1.65). Highest evidence: Growth DCF (80).
