Analysis
TSEC Corporation (6443) currently trades at 26.00 TWD, while our model-based Fair Value estimate is 24.20 TWD, implying the stock looks roughly 6.9% fairly valued today. The Quality Score stands at 38/100 (below-average quality), in the Technology 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).
Trailing-twelve-month revenue stands at 1.5B TWD. Revenue declined 45.2% year over year. It earns a return on equity of -62.1%. Net debt stands at 1.9B TWD. Fundamentals as of Jul 21, 2026
Our scenario range runs from 24.20 TWD (bear case) to 66.80 TWD (bull case); at 26.00 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 54% below its 52-week high and 118% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -7% fair-value upside, at -7%, 6443 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 9 models by family
Widest divergence: Asset-Based (4.75 TWD) versus DCF Models (2.87 TWD). Highest evidence: Growth DCF (80).
