Analysis
L&K Engineering Co (6139) currently trades at 802.00 TWD, while our model-based Fair Value estimate is 636.93 TWD, implying the stock looks roughly 20.6% overvalued today. The Quality Score stands at 73/100 (solid quality), in the Industrials sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: medium).
Over the trailing twelve months, L&K Engineering Co generated revenue of 77.5B TWD at a net margin of 9.2%. Revenue grew 141.3% year over year. It earns a return on equity of 39.0%. The balance sheet holds a net cash position of 43.5B TWD. Fundamentals as of Jul 19, 2026
Our scenario range runs from 477.69 TWD (bear case) to 1,018 TWD (bull case); at 802.00 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 216% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -45% fair-value upside, at -21%, 6139 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: DCF Models (1,494 TWD) versus Asset-Based (55.36 TWD). Highest evidence: Growth DCF (80).
