Analysis

Acon Optics Communications Inc (6820) currently trades at 294.00 TWD, while our model-based Fair Value estimate is 265.42 TWD, implying the stock looks roughly 9.7% fairly valued 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: medium).

Over the trailing twelve months, Acon Optics Communications Inc generated revenue of 840M TWD at a net margin of 0.8%. Revenue declined 12.3% year over year. It earns a return on equity of 1.7%. The balance sheet holds a net cash position of 66.9M TWD. Fundamentals as of Jul 21, 2026

Our scenario range runs from 199.15 TWD (bear case) to 296.46 TWD (bull case); at 294.00 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 34% below its 52-week high, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -61% fair-value upside, at -10%, 6820 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.

Model Bear Bear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull Bull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. Evidence
