ON Semiconductor holds the cleaner structural position, with the lead spread across profitability and growth. Westlake still leads on valuation and stability, which keeps the comparison from looking entirely one-sided. On the market side, ON Semiconductor is in better shape — its trend is intact while Westlake's trend has broken down. That puts structure and market broadly in agreement — ON Semiconductor's lead looks more confirmed than conflicted.
The comparison is based on similar long-term financial trajectories, not sector labels. Both peer scores are relative to the Russell 1000 universe, making them directly comparable.
The clearest separation starts in profitability, but growth adds another real layer to the result. The overall score gap is 11 points in favour of ON Semiconductor Corporation.
This pair is matched through long-term financial trajectory similarity within the selected peer universe.
This level of similarity points to a meaningful structural match, though not a tight one.
The clearest structural overlap shows up in margin trend and revenue growth trajectory.
Scores reflect position relative to comparable companies with similar long-term financial trajectories.
The largest gaps do not all point in the same direction.
Left means cheaper relative valuation. Higher means stronger structure.
ON Semiconductor Corporation is stronger, but the price setup still looks more supportive for Westlake Corporation.
Valuation position uses peer-relative PE percentile (idx_pct_pe) and Forward P/E where available.
Where ON and WLK each sit in their own 5-year price and valuation history.
Describes historical entry positioning only. Descriptive — not investment advice.
The profitability lead is mainly driven by a 25-point operating margin advantage.
Valuation still leans toward Westlake Corporation, so the lead is real without reading as one-way.
The lead is built on both profitability and growth — though valuation still provides a counterweight.

Rule-based, descriptive analysis only. Derived from peer percentile dimensions. Not investment advice. Peer groups are determined algorithmically based on structural similarity — not by sector classification alone.
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.
