Analysis

LeRain Technology Co (6921) currently trades at 65.20 TWD, while our model-based Fair Value estimate is 9.40 TWD, implying the stock looks roughly 85.6% overvalued today. The Quality Score stands at 43/100 (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).

Over the trailing twelve months, LeRain Technology Co generated revenue of 163M TWD at a net margin of -5.3%. Revenue declined 53.1% year over year. It earns a return on equity of -3.4%. The stock trades on a trailing P/E of 199.1. Fundamentals as of Jul 21, 2026

Our scenario range runs from 7.95 TWD (bear case) to 11.76 TWD (bull case); at 65.20 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 38% below its 52-week high and 19% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -67% fair-value upside, at -86%, 6921 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.

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
