What matters now
- A fairly wide model range ($15.06 to $29.67) leaves room in how you read the outcome.
- The price sits in the lower half of our model range, the side with the larger margin of safety.
- Read the verdict with care: some models are missing inputs, so the estimate scatters more than usual.

How to read this chart
60‑month range $4.37 – $27.53 · fair‑value band $15.06 – $29.67 · the $19.86 price screens below the $21.88 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Aug 20, 2026.
Analysis
United Microelectronics (UMC) currently trades at $19.86, while our model-based Fair Value estimate is $21.88, implying the stock looks roughly 9.2% undervalued today. The Quality Score stands at 65/100 (solid quality), in the Technology sector. Bull case: the Dividend Discount group reads highest at a median of $199.38 per share, and 25 of the 25 models we run sit above the $19.86 price. Bear case: the Asset-Based group reads lowest at $101.40, and 0 of the 25 models stay below the price. Evidence for this calculation is medium.
Over the trailing twelve months, United Microelectronics generated revenue of $241B at a net margin of 20.8%. Revenue grew 5.5% year over year. It earns a return on equity of 12.5%. The balance sheet holds a net cash position of $50.9B. Fundamentals as of Aug 20, 2026
Our scenario range runs from $15.06 (bear case) to $29.67 (bull case); at $19.86, 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 about 16% below its 52-week high and 203% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at −59% fair-value upside, at 10%, UMC 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 25 models by family
Widest divergence: Growth Earnings ($377.04) versus Asset-Based ($101.40). Highest evidence: FCF DCF (81).

Quality Score breakdown
Of which business quality 65 · Market factors (momentum, volatility) 62
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.
