- Solid quality (53/100) at a price below fair value, the discount is the argument here, not the business quality.
- A fairly wide model range (7.53 THB to 14.98 THB) leaves room in how you read the outcome.

Analysis
Thai Optical Group (TOG) currently trades at 7.30 THB, while our model-based Fair Value estimate is 11.99 THB, implying the stock looks roughly 64.3% undervalued today. The Quality Score stands at 53/100 (solid quality), in the Healthcare 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, Thai Optical Group generated revenue of 3.6B THB at a net margin of 9.4%. Revenue grew 1.3% year over year. It earns a return on equity of 13.6%. Net debt stands at 1.4B THB. Fundamentals as of Jul 11, 2026
Our scenario range runs from 7.53 THB (bear case) to 14.98 THB (bull case); at 7.30 THB, the current price sits below 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 10% below its 52-week high and 22% above its 52-week low, currently above its 200-day average. For context, the median of 10 Healthcare peers we cover trades at -43% fair-value upside, at 64%, TOG 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 26 models by family

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