What matters now
- The price sits above even our optimistic bull case (¥1.22). The favourable scenario is already priced in.
- Weak quality (44/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
- A fairly wide model range (¥0.6400 to ¥1.22) leaves room in how you read the outcome.

Analysis
Dongguan Kingsun Optoelectronic Co (002638) currently trades at ¥3.71, while our model-based Fair Value estimate is ¥0.9800, implying the stock looks roughly 73.6% overvalued today. The Quality Score stands at 44/100 (below-average 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: low).
Over the trailing twelve months, Dongguan Kingsun Optoelectronic Co generated revenue of 350M CNY at a net margin of -98.2%. Revenue declined 24.2% year over year. It earns a return on equity of -16.7%. The balance sheet holds a net cash position of 191M CNY. Fundamentals as of Jul 22, 2026
Our scenario range runs from ¥0.6400 (bear case) to ¥1.22 (bull case); at ¥3.71, 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 28% below its 52-week high and 69% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -48% fair-value upside, at -74%, 002638 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.
