Share price −16.5% over the past month.

Below-average quality, and screening another 80% overvalued on our models.

What matters now

  • The price sits above even our optimistic bull case (¥7.26). The favourable scenario is already priced in.
  • Weak quality (43/100) and above fair value at the same time, the margin of safety is missing on both counts.
  • A fairly wide model range (¥3.91 to ¥7.26) leaves room in how you read the outcome.

Analysis

Guangdong Jiayuan Technology Co (688388) currently trades at ¥28.05, while our model-based Fair Value estimate is ¥5.59, implying the stock looks roughly 80.1% overvalued today. The Quality Score stands at 43/100 (below-average quality), in the Basic Materials 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, Guangdong Jiayuan Technology Co generated revenue of 11.1B CNY at a net margin of 1.4%. Revenue grew 73.9% year over year. It earns a return on equity of 2.0%. Net debt stands at 2.6B CNY. Fundamentals as of Jul 12, 2026

Our scenario range runs from ¥3.91 (bear case) to ¥7.26 (bull case); at ¥28.05, 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 58% below its 52-week high and 72% above its 52-week low, currently below its 200-day average. For context, the median of 10 Basic Materials peers we cover trades at -46% fair-value upside, at -80%, 688388 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.

Model Bear Bear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull Bull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. Evidence
