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
    Pairwise Constituent Overlap Math

    Calculates exact capital duplication between any two funds using Σ min(w_A,i, w_B,i) with shared constituent counts and unique weight distributions.

  2. 02
    True Total Cost of Ownership (TCO)

    Unifies statutory expense ratio, median 30-day bid-ask spread drag amortized across holding horizons, and annual tracking difference into a single effective cost metric.

  3. 03
    Breakeven Holding Horizon (H*)

    Computes the exact holding duration required for a lower annual expense ratio to fully amortize wider secondary market trading spreads.

  4. 04
    Full 11 GICS Sector Parity

    Institutional coverage across all 11 GICS sector ETFs, major style boxes, aggregate bond ladders, international developed & emerging markets, and REITs.

  5. 05
    Top 25 U.S. Sponsor Intelligence

    Forensic directory covering $10.8T+ in U.S. ETF assets, tracking the Big Three 79.2% market concentration and asset-weighted fee efficiency (c̄).

  6. 06
    Statutory SEC Provenance

    100% authentic observations sourced directly from SEC EDGAR Form 497K prospectuses, Form N-PORT schedules, and Form N-CEN census filings with zero synthetic models.

How it works

Inputs, analysis, outputs

A high-level description of how the capability goes from raw inputs to the outputs you see inside the workspace.

  1. 01Step 1

    1. Select & Pair Funds

    Choose any two exchange-traded funds across index, sector, factor, or income sleeves to inspect underlying holdings.

  2. 02Step 2

    2. Compute Capital Look-Through

    Algorithms evaluate identical underlying equity weights and compute effective capital duplication percentage alongside unique sleeve exposure.

  3. 03Step 3

    3. Optimize Execution & Horizon

    Review the True TCO curve and breakeven holding period to determine optimal vehicle selection for short-term trading versus multi-year compounding.
