Analysis
Taiwan Steel Union Co (6581) currently trades at 108.00 TWD, while our model-based Fair Value estimate is 123.89 TWD, implying the stock looks roughly 14.7% undervalued today. The Quality Score stands at 69/100 (solid quality), in the Industrials 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, Taiwan Steel Union Co generated revenue of 2.2B TWD at a net margin of 31.3%. Revenue declined 11.7% year over year. It earns a return on equity of 16.9%. The balance sheet holds a net cash position of 157M TWD. Fundamentals as of Jul 21, 2026
Our scenario range runs from 78.88 TWD (bear case) to 162.01 TWD (bull case); at 108.00 TWD, 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 6% below its 52-week high and 10% above its 52-week low, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -40% fair-value upside, at 15%, 6581 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
Widest divergence: Growth Earnings (111.70 TWD) versus Asset-Based (27.02 TWD). Highest evidence: Growth DCF (80).
