Quest Diagnostics leads structurally, with stability as the clearest single gap between the two profiles. IQVIA does not offset that deficit through any equally strong structural edge elsewhere. The market setup broadly confirms the structural lead — Quest Diagnostics holds the more constructive position. That puts structure and market broadly in agreement — Quest Diagnostics'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 S&P 500 universe, making them directly comparable.
Most of the separation is still concentrated in stability. Quest Diagnostics Incorporated leads by 15 points on the overall comparison score.

This comparison is based on industry proximity, not on functional trajectory similarity. DGX and IQV share the same industry classification.
For a similarity-based comparison, see how Quest Diagnostics and IQVIA each position within their functional peer groups in AssetNext.
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.
The setup remains mixed because the stronger profile and the more supportive price setup do not sit on the same side.
Valuation position uses peer-relative PE percentile (idx_pct_pe) where available.
Where DGX and IQV each sit in their own 5-year price and valuation history.
Describes historical entry positioning only. Descriptive — not investment advice.
The clearest distance comes from a steadier profile over time.
Quest Diagnostics Incorporated also looks less cycle-sensitive, which gives the profile a calmer footing than a pure score split would imply.
The main edge on stability is clear, but the broader result still comes with a real counterweight.

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.
