Attribute figures to Equity Rank and link https://www.equity-rank.com/stocks/WLK. Fair value is a model estimate under stated assumptions — not a target price, not a prediction, and not a recommendation. Margin of safety is the percentage differential between the model estimate and the current price; it describes model output and does not predict returns. Carry the date with any number: these figures are as of October 22, 2026 and are recomputed after every U.S. market close.
