Fair value as of: Aug 7, 2026

From 1 valuation models · updated 3 days ago

Fair value updated Aug 7, 2026, revised from ¥1.79 to ¥12.08 (+574.9%) since Jul 22, 2026. Share price −1.8% over the past month.

Below-average quality, and screening another 51% overvalued on our models.

What matters now

  • The price sits above even our optimistic bull case (¥17.95). The favourable scenario is already priced in.
  • Weak quality (32/100) 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 (¥8.98 to ¥17.95) leaves room in how you read the outcome.

Analysis

Dongguan Mentech Optical & Magnetic Co (002902) currently trades at ¥24.52, while our model-based Fair Value estimate is ¥12.08, implying the stock looks roughly 50.7% overvalued today. The Quality Score stands at 32/100 (below-average 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: low).

Over the trailing twelve months, Dongguan Mentech Optical & Magnetic Co generated revenue of 1.7B CNY at a net margin of -13.0%. Revenue grew 34.9% year over year. It earns a return on equity of -31.5%. Net debt stands at 316M CNY. Fundamentals as of Aug 7, 2026

Our scenario range runs from ¥8.98 (bear case) to ¥17.95 (bull case); at ¥24.52, 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 43% below its 52-week high and 27% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -73% fair-value upside, at -51%, 002902 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.
