Analysis
Oriental System Technology Inc (6819) currently trades at 38.95 TWD, while our model-based Fair Value estimate is 9.95 TWD, implying the stock looks roughly 74.5% overvalued today. The Quality Score stands at 54/100 (solid 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: high).
Over the trailing twelve months, Oriental System Technology Inc generated revenue of 224M TWD at a net margin of -7.4%. Revenue declined 2.1% year over year. It earns a return on equity of -5.0%. The balance sheet holds a net cash position of 73.5M TWD. Fundamentals as of Jul 23, 2026
Our scenario range runs from 8.01 TWD (bear case) to 11.90 TWD (bull case); at 38.95 TWD, the current price sits above 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 47% below its 52-week high and 95% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -67% fair-value upside, at -74%, 6819 screens richer 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 16 models by family
Widest divergence: Dividend Discount (42.42 TWD) versus Asset-Based (6.42 TWD). Highest evidence: Growth DCF (80).
