Sumida Corporation (SDAEF) Fair Value & Analysis

Technology · US · Market cap $224M

Below-average quality, screening 121% undervalued on our models.

What matters now

• The large discount to fair value meets weak quality (44/100). That raises the risk this is a value trap rather than a bargain.
• The price is below even our cautious bear case ($10.69). The market is more pessimistic than our downside scenario.
• A fairly wide model range ($10.69 to $21.83) leaves room in how you read the outcome.

Analysis

Sumida Corporation (SDAEF) currently trades at $6.78, while our model-based Fair Value estimate is $15.00, implying the stock looks roughly 121.2% undervalued today. The Quality Score stands at 44/100 (below-average quality), in the Technology 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: medium), always confirm before acting.

Over the trailing twelve months, Sumida Corporation generated revenue of $150B at a net margin of 2.5%. Revenue grew 8.6% year over year. It earns a return on equity of 6.1%. Net debt stands at $50.3B. Fundamentals as of Jul 25, 2026

Our scenario range runs from $10.69 (bear case) to $21.83 (bull case); at $6.78, 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 near its 52-week high, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -73% fair-value upside, at 121%, SDAEF 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.

Widest divergence: Multiples ($16.19) versus Earnings-Based ($6.99). Highest evidence: Growth DCF (80).

Frequently asked questions

How we calculate Fair Value

Each company is valued through a stack of independent intrinsic-value models (DCF variants, residual-income, multiples and more), blended into one family-balanced consensus and weighted by how much trustworthy data backs it. A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
