EFUN Technology Co (3523) Fair Value & Analysis
Technology · TW · Market cap 900M TWD
Fair value as of: Jul 21, 2026
From 3 valuation models · updated 20 days ago
Share price +2.3% over the past month.
Below-average quality, and screening another 72% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (6.63 TWD). The favourable scenario is already priced in.
- Weak quality (17/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
- A fairly wide model range (3.31 TWD to 6.63 TWD) leaves room in how you read the outcome.

Analysis
EFUN Technology Co (3523) currently trades at 15.75 TWD, while our model-based Fair Value estimate is 4.44 TWD, implying the stock looks roughly 71.8% overvalued today. The Quality Score stands at 17/100 (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: low).
Trailing-twelve-month revenue stands at 90.1M TWD. Revenue declined 55.5% year over year. It earns a return on equity of -21.0%. Net debt stands at 1.2B TWD. Fundamentals as of Jul 21, 2026
Our scenario range runs from 3.31 TWD (bear case) to 6.63 TWD (bull case); at 15.75 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 32% below its 52-week high and 65% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -73% fair-value upside, at -72%, 3523 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 3 models by family
Widest divergence: Dividend Discount (8.24 TWD) versus Asset-Based (4.44 TWD). Highest evidence: Gordon GGM (70).
