Analysis
Sinopec Oilfield Service Corporation (600871) currently trades at ¥2.21, while our model-based Fair Value estimate is ¥0.4900, implying the stock looks roughly 77.8% overvalued today. The Quality Score stands at 47/100 (below-average quality), in the Energy 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, Sinopec Oilfield Service Corporation generated revenue of 81.1B CNY at a net margin of 0.8%. Revenue grew 2.4% year over year. It earns a return on equity of 6.9%. Net debt stands at 24.8B CNY. Fundamentals as of Aug 8, 2026
Our scenario range runs from ¥0.3600 (bear case) to ¥0.7400 (bull case); at ¥2.21, 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 15% above its 52-week low, currently below its 200-day average. For context, the median of 10 Energy peers we cover trades at -45% fair-value upside, at -78%, 600871 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 26 models by family
Widest divergence: Growth DCF (¥2.41) versus Asset-Based (¥0.3300). Highest evidence: Growth DCF (80).
