Pentair vs The Weir Group: Which Stock Looks Stronger in 2026?

Pentair holds the cleaner structural position, with the lead spread across valuation and profitability. The Weir still has the edge on stability, which keeps the comparison from looking entirely one-sided. The market setup is currently leaning toward The Weir, which does not confirm the structural lead. That leaves a split case: the structural lead stays with Pentair, but the market is not currently confirming it.

The comparison is based on similar long-term financial trajectories, not sector labels.

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.

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.
