Fair value as of: Jul 22, 2026

From 2 valuation models · updated 19 days ago

Fair value updated Jul 22, 2026, revised from 4,875 KRW to 4,800 KRW (−1.5%) since Jun 25, 2026. Share price +6.6% over the past month.

Below-average quality, and screening another 56% overvalued on our models.

What matters now

  • The price sits above even our optimistic bull case (7,164 KRW). The favourable scenario is already priced in.
  • Weak quality (43/100) 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 (3,582 KRW to 7,164 KRW) leaves room in how you read the outcome.

Analysis

Seronics Co (042600) currently trades at 10,820 KRW, while our model-based Fair Value estimate is 4,800 KRW, implying the stock looks roughly 55.6% 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: low).

Over the trailing twelve months, Seronics Co generated revenue of 159B KRW at a net margin of -10.8%. Revenue declined 10.9% year over year. It earns a return on equity of -16.9%. Net debt stands at 66.3B KRW. Fundamentals as of Jul 22, 2026

Our scenario range runs from 3,582 KRW (bear case) to 7,164 KRW (bull case); at 10,820 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 53% below its 52-week high and 64% 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 -56%, 042600 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
