What matters now
- The large discount to fair value meets weak quality (20/100). That raises the risk this is a value trap rather than a bargain.
- 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 (£0.0540 to £0.1020) leaves room in how you read the outcome.

Analysis
Petra Diamonds Limited (PDL) currently trades at £0.0595, while our model-based Fair Value estimate is £0.0780, implying the stock looks roughly 31.1% undervalued today. The Quality Score stands at 20/100 (below-average quality), in the Basic Materials sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: low), always confirm before acting.
Over the trailing twelve months, Petra Diamonds Limited generated revenue of £192M at a net margin of -95.8%. Revenue declined 13.0% year over year. Net debt stands at £212M. Fundamentals as of Aug 13, 2026
Our scenario range runs from £0.0540 (bear case) to £0.1020 (bull case); at £0.0595, the current price sits within 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. For context, the median of 10 Basic Materials peers we cover trades at -45% fair-value upside, at 31%, PDL 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.
All 3 models by family
Widest divergence: Asset-Based (£0.1500) versus Dividend Discount (£0.0600). Highest evidence: Gordon GGM (70).
