Analysis
Zhejiang Tuna Environmental Science & TechnologyCo.,Ltd. (603177) currently trades at ¥9.35, while our model-based Fair Value estimate is ¥2.42, implying the stock looks roughly 74.1% overvalued today. The Quality Score stands at 40/100 (below-average quality), in the Industrials 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, Zhejiang Tuna Environmental Science & TechnologyCo.,Ltd. generated revenue of 1.1B CNY at a net margin of -5.0%. Revenue declined 9.0% year over year. It earns a return on equity of -15.4%. Net debt stands at 534M CNY. Fundamentals as of Aug 10, 2026
Our scenario range runs from ¥2.25 (bear case) to ¥3.55 (bull case); at ¥9.35, 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 47% below its 52-week high and 13% above its 52-week low, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -46% fair-value upside, at -74%, 603177 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 15 models by family
Widest divergence: Multiples (¥4.39) versus Asset-Based (¥1.10). Highest evidence: Growth DCF (80).
