What matters now
- A high-quality business (quality 79/100), yet the market already pays well above fair value. Quality at a full price, with little margin of safety.
- The price sits above even our optimistic bull case (¥334.34). The favourable scenario is already priced in.
- The model range is unusually wide (¥91.61 to ¥334.34). The outcome hinges heavily on assumptions, so read the point estimate with caution.

Analysis
Eoptolink Technology Inc (300502) currently trades at ¥421.87, while our model-based Fair Value estimate is ¥155.05, implying the stock looks roughly 63.3% overvalued today. We read business quality at 79/100 (high quality), in the Technology 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, Eoptolink Technology Inc generated revenue of 29.1B CNY at a net margin of 36.9%. Revenue grew 105.8% year over year. It earns a return on equity of 70.7%. The balance sheet holds a net cash position of 1.6B CNY. Fundamentals as of Jul 17, 2026
Our scenario range runs from ¥91.61 (bear case) to ¥334.34 (bull case); at ¥421.87, 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 48% below its 52-week high and 334% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -61% fair-value upside, at -63%, 300502 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 Earnings (¥308.33) versus Dividend Discount (¥3.94). Highest evidence: Residual Income (76).
