Analysis
Zhejiang Goldensea Envi Tech C (603311) currently trades at ¥28.33, while our model-based Fair Value estimate is ¥5.66, implying the stock looks roughly 80.0% overvalued today. The Quality Score stands at 63/100 (solid 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 Goldensea Envi Tech C generated revenue of 850M CNY at a net margin of 8.3%. Revenue declined 2.6% year over year. It earns a return on equity of 5.2%. The balance sheet holds a net cash position of 191M CNY. Fundamentals as of Aug 13, 2026
Our scenario range runs from ¥4.45 (bear case) to ¥7.07 (bull case); at ¥28.33, 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 31% below its 52-week high and 181% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -31% fair-value upside, at -80%, 603311 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.

Quality Score breakdown
Of which business quality 63 · Market factors (momentum, volatility) 68
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
