What matters now
- The large discount to fair value meets weak quality (38/100). That raises the risk this is a value trap rather than a bargain.
- The price is below even our cautious bear case ($47.75). The market is more pessimistic than our downside scenario.
Price vs Fair Value (5 years)
White line = price, green steps = our fair value per fiscal year, dashed = 300-day average. As of Aug 30, 2026.
How to read this chart
60‑month range $9.99 – $67.00 · fair‑value band $47.75 – $85.37 · the $40.99 price screens below the $66.56 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). 1 fiscal year is left out: there the valuation rested on only a fraction of the usual models. Dashed = 300-day average. As of Aug 30, 2026.
Analysis
Sumco Corp ADR (SUOPY) currently trades at $40.99, while our model-based Fair Value estimate is $66.56, implying the stock looks roughly 38.4% undervalued today. The Quality Score stands at 38/100 (below-average quality), in the Technology sector. Bull case: the Multiples group reads highest at a median of $66.56 per share, and 1 of the 4 models we run sit above the $40.99 price. Bear case: the Asset-Based group reads lowest at $13.75, and 3 of the 4 models stay below the price. Evidence for this calculation is medium.
Over the trailing twelve months, Sumco Corp ADR generated revenue of $409B at a net margin of −5.7%. Revenue declined 1.0% year over year. It earns a return on equity of −3.5%. Net debt stands at $287B. Fundamentals as of Aug 30, 2026
Our scenario range runs from $47.75 (bear case) to $85.37 (bull case); at $40.99, 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 26% below its 52-week high and 178% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at −71% fair-value upside, at 62%, SUOPY screens cheaper than that median.
Fair Value models
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 4 models by family
Widest divergence: Multiples ($66.56) versus Dividend Discount ($2.76). Highest evidence: EV/EBITDA (67).

Quality Score breakdown
Of which business quality 38 · Market factors (momentum, volatility) 61
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.
