Analysis
Dongguan Golden Sun Abrasives Co Ltd (300606) currently trades at ¥36.20, while our model-based Fair Value estimate is ¥20.33, implying the stock looks roughly 43.8% overvalued today. The Quality Score stands at 61/100 (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, Dongguan Golden Sun Abrasives Co Ltd generated revenue of 544M CNY at a net margin of 3.7%. Revenue declined 0.4% year over year. It earns a return on equity of 3.1%. Net debt stands at 108M CNY. Fundamentals as of Aug 13, 2026
Our scenario range runs from ¥15.28 (bear case) to ¥25.45 (bull case); at ¥36.20, 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 20% below its 52-week high and 97% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -57% fair-value upside, at -44%, 300606 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 23 models by family
Widest divergence: DCF Models (¥6.76) versus Earnings-Based (¥1.24). Highest evidence: Growth DCF (80).
