What matters now
- The model range is unusually wide ($40.50 to $145.74). The outcome hinges heavily on assumptions, so read the point estimate with caution.
- Evidence is limited here (fewer models, shorter history), so the fair value is a rougher estimate than usual.

How to read this chart

Analysis
Westlake Corporation (WLK) currently trades at $77.47, while our model-based Fair Value estimate is $87.62, implying the stock looks roughly 13.1% undervalued today. We read business quality at 36/100 (below-average quality), in the Basic Materials sector. Bull case: trading below our estimate, it may offer upside if the fundamentals hold. Bear case: a low price can be a value trap when quality is weak or the data is thin (evidence: low), always confirm before acting.
Over the trailing twelve months, Westlake Corporation generated revenue of $11.0B at a net margin of -14.9%. Revenue declined 6.8% year over year. It earns a return on equity of -16.0%. Net debt stands at $3.7B. Fundamentals as of Jul 18, 2026
Our scenario range runs from $40.50 (bear case) to $145.74 (bull case); at $77.47, 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 37% below its 52-week high and 40% above its 52-week low, currently below its 200-day average. For context, the median of 10 Basic Materials peers we cover trades at -58% fair-value upside, at 13%, WLK 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.
All 3 models by family

A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
