What matters now
- The price is below even our cautious bear case ($71.89). The market is more pessimistic than our downside scenario.
- The model range is unusually wide ($71.89 to $222.36). The outcome hinges heavily on assumptions, so read the point estimate with caution.
- Solid quality (67/100) at a price below fair value, the discount is the argument here, not the business quality.

How to read this chart
60‑month range $6.70 – $50.96 · fair‑value band $71.89 – $222.36 · the $46.18 price screens below the $119.47 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Aug 30, 2026.
Analysis
Rigel Pharmaceuticals Inc (RIGL) currently trades at $46.18, while our model-based Fair Value estimate is $119.47, implying the stock looks roughly 61.3% undervalued today. The Quality Score stands at 67/100 (solid quality), in the Healthcare sector. Bull case: the Growth Earnings group reads highest at a median of $921.62 per share, and 22 of the 23 models we run sit above the $46.18 price. Bear case: the Asset-Based group reads lowest at $14.18, and 1 of the 23 models stay below the price. Evidence for this calculation is high.
Trailing-twelve-month revenue stands at $300M. Revenue grew 10.3% year over year. It earns a return on equity of 174.1%. Net debt stands at $12.7M. Fundamentals as of Aug 30, 2026
Our scenario range runs from $71.89 (bear case) to $222.36 (bull case); at $46.18, 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 12% below its 52-week high and 155% above its 52-week low, currently above its 200-day average. For context, the median of 10 Healthcare peers we cover trades at −59% fair-value upside, at 159%, RIGL screens cheaper than that median.
Fair Value models
This estimate rests on fiscal year 2025 figures, and about 8 months have passed since. In that time the company retained roughly $12.90 per share, which is 10.8 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced 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. Every input is real reported data, nothing guessed.
All 23 models by family
Widest divergence: Growth Earnings ($921.62) versus Asset-Based ($14.18). Highest evidence: FCF DCF (75).

Quality Score breakdown
Of which business quality 69 · Market factors (momentum, volatility) 55
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
