Analysis
LongDa Construction & Development Corporation (5519) currently trades at 27.85 TWD, while our model-based Fair Value estimate is 80.35 TWD, implying the stock looks roughly 188.5% undervalued today. The Quality Score stands at 72/100 (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, LongDa Construction & Development Corporation generated revenue of 5.4B TWD at a net margin of 20.3%. Revenue declined 9.5% year over year. It earns a return on equity of 20.1%. Net debt stands at 3.9B TWD. Fundamentals as of Jul 21, 2026
Our scenario range runs from 57.59 TWD (bear case) to 100.44 TWD (bull case); at 27.85 TWD, 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 22% below its 52-week high and 3% above its 52-week low, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -45% fair-value upside, at 189%, 5519 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
