Analysis
Diamond Building Products Public Company (DRT) currently trades at 5.35 THB, while our model-based Fair Value estimate is 5.77 THB, implying the stock looks roughly 7.9% fairly valued today. The Quality Score stands at 63/100 (solid quality), in the Industrials 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, Diamond Building Products Public Company generated revenue of 4.6B THB at a net margin of 6.9%. Revenue declined 4.2% year over year. It earns a return on equity of 13.0%. Net debt stands at 1.0B THB. Fundamentals as of Jul 18, 2026
Our scenario range runs from 3.83 THB (bear case) to 8.32 THB (bull case); at 5.35 THB, 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. The share trades near its 52-week high and 29% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -33% fair-value upside, at 8%, DRT 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 25 models by family
