Parker-Hannifin holds the cleaner structural position, with profitability as the main driver and growth adding further support. On the market side, Parker-Hannifin is in better shape — its trend is intact while The Weir's trend has broken down. That puts structure and market broadly in agreement — Parker-Hannifin'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 (PH: S&P 500, WEIR.L: STOXX 600).
The clearest separation starts in profitability, but growth adds another real layer to the result. The overall score gap is 12 points in favour of Parker-Hannifin Corporation.
Both operate in: Specialty Industrial Machinery
This comparison is based on industry proximity, not on functional trajectory similarity. PH and WEIR.L share the same industry classification.

Score differences across key dimensions.
Left means cheaper relative valuation. Higher means stronger structure.
Parker-Hannifin Corporation still looks stronger overall, though current pricing looks more supportive for The Weir Group PLC.

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.
