A solid business, but screening 39% overvalued on our models.

What matters now

  • The price sits above even our optimistic bull case (1,672 KRW). The favourable scenario is already priced in.
  • Solid but not exceptional quality (56/100) and above fair value, neither a clear bargain nor a standout compounder.
  • A fairly wide model range (898.77 KRW to 1,672 KRW) leaves room in how you read the outcome.

Analysis

Rnt-X Co (123010) currently trades at 2,100 KRW, while our model-based Fair Value estimate is 1,285 KRW, implying the stock looks roughly 38.8% overvalued today. The Quality Score stands at 56/100 (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, Rnt-X Co generated revenue of 37.3B KRW at a net margin of -5.2%. Revenue declined 10.2% year over year. It earns a return on equity of -6.7%. Net debt stands at 8.9B KRW. Fundamentals as of Jul 22, 2026

Our scenario range runs from 898.77 KRW (bear case) to 1,672 KRW (bull case); at 2,100 KRW, 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 33% below its 52-week high and 222% above its 52-week low, currently above its 200-day average. For context, the median of 10 Technology peers we cover trades at -75% fair-value upside, at -39%, 123010 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
