Interactive Brokers holds the cleaner structural position, with the lead spread across profitability and growth. BlackRock still leads on growth and valuation, which keeps the comparison from looking entirely one-sided. The market setup is mixed, without a decisive signal in either direction. The market is not adding a decisive signal either way — the structural read carries the weight.
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 stability adds another real layer to the result.
This comparison is anchored in long-term financial trajectory similarity within the selected peer universe.
This level of similarity signals a strong structural match, even though some dimensions still separate the two companies.
The clearest structural overlap shows up in investment intensity and recent revenue growth.
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.
Interactive Brokers Group, Inc. still looks cheaper, even though BlackRock, Inc. remains structurally stronger.
Valuation position uses peer-relative PE percentile (idx_pct_pe) where available.
Where BLK and IBKR 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 41-point operating margin advantage.
Earnings growth also leans toward BLK, which keeps the score lead from reading as a full growth sweep.
Profitability settles the comparison, while pricing and growth keep the broader setup from looking fully aligned.

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.
