What matters now

  • The price sits above even our optimistic bull case (33.01 TWD). The favourable scenario is already priced in.
  • The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
  • Solid but not exceptional quality (66/100) and above fair value, neither a clear bargain nor a standout compounder.

Analysis

Formosa Petrochemical Corp (6505) currently trades at 78.10 TWD, while our model-based Fair Value estimate is 26.41 TWD, implying the stock looks roughly 195.8% overvalued today. The Quality Score stands at 66/100 (solid quality), in the Energy sector. Bull case: the Growth DCF group reads highest at a median of 31.71 TWD per share, and 0 of the 24 models we run sit above the 78.10 TWD price. Bear case: the Dividend Discount group reads lowest at 8.60 TWD, and 24 of the 24 models stay below the price. Evidence for this calculation is low.

Over the trailing twelve months, Formosa Petrochemical Corp generated revenue of 615B TWD at a net margin of 4.3%. Revenue declined 6.5% year over year. It earns a return on equity of 7.8%. The balance sheet holds a net cash position of 26.4B TWD. Fundamentals as of Aug 22, 2026

Our scenario range runs from 19.81 TWD (bear case) to 33.01 TWD (bull case); at 78.10 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 near its 52-week high and 124% above its 52-week low, currently above its 200-day average. For context, the median of 10 Energy peers we cover trades at −59% fair-value upside, at −66%, 6505 screens richer than that median.

Fair Value models

Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced 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. Every input is real reported data, nothing guessed.

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

Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.

All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
