Fair value as of: Jul 23, 2026

Fair value updated Jul 23, 2026, revised from 19.90 TWD to 20.07 TWD (+0.9%) since Jul 11, 2026. Share price −16.8% over the past month.
Below-average quality, screening 40% undervalued on our models.
What matters now
- The large discount to fair value meets weak quality (40/100). That raises the risk this is a value trap rather than a bargain.
- 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 (13.27 TWD to 24.93 TWD) leaves room in how you read the outcome.

Analysis
Tainergy Tech Co (4934) currently trades at 14.35 TWD, while our model-based Fair Value estimate is 20.07 TWD, implying the stock looks roughly 39.9% undervalued today. The Quality Score stands at 40/100 (below-average quality), in the Technology 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: low), always confirm before acting.
Trailing-twelve-month revenue stands at 111M TWD. Revenue grew 133.2% year over year. It earns a return on equity of -21.0%. The balance sheet holds a net cash position of 124M TWD. Fundamentals as of Jul 23, 2026
Our scenario range runs from 13.27 TWD (bear case) to 24.93 TWD (bull case); at 14.35 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 37% below its 52-week high and 57% 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 40%, 4934 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 (8.08 TWD) versus Asset-Based (4.63 TWD). Highest evidence: Gordon GGM (70).
