Analysis
Xiamen Amoytop Biotech Co (688278) currently trades at ¥55.96, while our model-based Fair Value estimate is ¥48.18, implying the stock looks roughly 13.9% overvalued today. The Quality Score stands at 68/100 (solid quality), in the Healthcare 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: medium).
Over the trailing twelve months, Xiamen Amoytop Biotech Co generated revenue of 3.8B CNY at a net margin of 26.5%. Revenue grew 18.5% year over year. It earns a return on equity of 31.8%. The balance sheet holds a net cash position of 369M CNY. Fundamentals as of Jul 12, 2026
Our scenario range runs from ¥30.43 (bear case) to ¥117.47 (bull case); at ¥55.96, the current price sits within 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 40% below its 52-week high and 5% above its 52-week low, currently below its 200-day average. For context, the median of 10 Healthcare peers we cover trades at -43% fair-value upside, at -14%, 688278 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 26 models by family
