ArcelorMittal vs Westlake: Which Stock Looks Stronger in 2026?

ArcelorMittal holds the cleaner structural position, with the lead spread across profitability and growth. Westlake does not offset that deficit through any equally strong structural edge elsewhere. On the market side, ArcelorMittal is in better shape — its trend is intact while Westlake's trend has broken down. That puts structure and market broadly in agreement — ArcelorMittal's lead looks more confirmed than conflicted.

The comparison is based on similar long-term financial trajectories, not sector labels. Peer scores are normalised within each company's primary universe (MT.AS: STOXX 600, WLK: Russell 1000).

How AssetNext Peer Scores Work

AssetNext scores reflect each company's structural position within its functional peer group — not a ranking against all stocks simultaneously. Peers are identified by similarity across eight financial dimensions, including revenue growth trajectory, margin structure, capital intensity, and earnings stability. A score of 75 means the company ranks in the top quartile within its own peer group, not the entire market.

Four dimension scores drive the overall peer score: Growth (revenue trajectory and expansion dynamics), Quality (margin structure and capital efficiency), Valuation (peer-relative pricing on standard multiples), and Stability (earnings consistency and financial predictability). Each dimension is scored 0–100 relative to the peer group, then combined into an overall peer score using equal weighting.

Because scores are peer-relative, the same company can have slightly different scores in different index universes. On comparison pages, both companies are shown within their shared peer universe wherever possible — so the scores are directly comparable. The peer basis is stated on each score card.

Scores are recalculated periodically as underlying financial data is updated. All analysis is descriptive and rule-based — AssetNext describes structural realities and never issues buy, sell or hold recommendations.
