Healthcare · TW · Market cap 1.1B TWD
Fair value as of: Jul 21, 2026
From 1 valuation models · updated 20 days ago
Share price −5.1% over the past month.
Below-average quality, and screening another 85% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (4.64 TWD). The favourable scenario is already priced in.
- Weak quality (23/100) 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 (2.45 TWD to 4.64 TWD) leaves room in how you read the outcome.

Analysis
Diamond Biotechnology Co (6815) currently trades at 25.00 TWD, while our model-based Fair Value estimate is 3.71 TWD, implying the stock looks roughly 85.1% overvalued today. The Quality Score stands at 23/100 (below-average quality), in the Healthcare 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, Diamond Biotechnology Co generated revenue of 501M TWD at a net margin of -14.0%. Revenue declined 51.7% year over year. It earns a return on equity of -12.1%. Net debt stands at 83.2M TWD. Fundamentals as of Jul 21, 2026
Our scenario range runs from 2.45 TWD (bear case) to 4.64 TWD (bull case); at 25.00 TWD, 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 68% below its 52-week high, currently below its 200-day average. For context, the median of 10 Healthcare peers we cover trades at -22% fair-value upside, at -85%, 6815 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.
