ETF Constituent Overlap & Dual-Fund Concentration Engine

Inspect hidden equity duplication, shared capital weight, and genuine portfolio diversification across any two exchange-traded funds.

Many allocators hold redundant index funds unknowingly paying double management fees on identical mega-cap shares. Vantage computes mathematical look-through overlap from statutory Form N-PORT filings.

What it covers

What this capability surfaces

A grounded list of the features and outputs the matching workspace surface delivers today. Each row below maps directly to the corresponding element of the live product — nothing is aspirational or invented.

Illustrative Capability View
  1. 01
    Constituent-Weighted Overlap Math

    Computes the exact dollar-weighted intersection of identical equity holdings between fund pairs using the formula sum(min(w_A,i, w_B,i)).

  2. 02
    Look-Through Capital Duplication

    Decomposes dual-fund allocations into genuine unique equity exposure versus overlapping capital concentration across mega-cap market leaders.

  3. 03
    Top 20 Duplicate Holdings Matrix

    Surfaces individual company weightings inside both funds, identifying where single-stock exposure quietly exceeds institutional risk thresholds.

  4. 04
    Sector & Thematic Correlation Check

    Detects synthetic concentration risk across GICS sectors when holding thematic or growth sleeves alongside broad-market core anchors.

  5. 05
    Automated Form N-PORT SEC Sync

    100% authentic constituent schedules updated directly from statutory SEC EDGAR filings with zero estimated or synthetic baskets.
