Analysis
Big Yellow Group (BYG) currently trades at £8.85, while our model-based Fair Value estimate is £9.01, implying the stock looks roughly 1.8% fairly valued today. The Quality Score stands at 49/100 (below-average quality), in the Real Estate 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: high), always confirm before acting.
Over the trailing twelve months, Big Yellow Group generated revenue of £209M at a net margin of 59.7%. Revenue grew 2.5% year over year. It earns a return on equity of 4.8%. Net debt stands at £493M. Fundamentals as of Jul 17, 2026
Our scenario range runs from £6.13 (bear case) to £10.31 (bull case); at £8.85, 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 Real Estate peers we cover trades at -45% fair-value upside, at 2%, BYG 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 14 models by family
Widest divergence: Economic Profit (£9.63) versus Growth DCF (£4.02). Highest evidence: Residual Income (76).

A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
