SEC. 01 — WHAT THIS PILLAR DOES
Rotation, measured
Relative strength and trend state across the sector suite, scored consistently, so "energy is leading" is a measurement with a date on it — not a vibe.
Exposure, decomposed
What a fund actually holds: sector weights, top-name concentration and factor tilts from public issuer holdings files — because two ETFs with similar names can be very different risks.
Correlation, before you need it
Rolling correlations across funds and to the index, so diversification claims can be checked against data — especially in the drawdowns where correlations tend to rise.
SEC. 02 — WHAT DATA POWERS IT
US consolidated equity market data
ETF prices, volume and history via licensed consolidated-tape distributors.
Issuer holdings & exposure files
Publicly published daily holdings and sector weights from fund issuers.
SEC filings (N-PORT, prospectuses)
Public structural and fee data for covered funds.
FRED macro series
Rates and macro context used in the rotation and regime layers.
DATA MAY BE DELAYED. Holdings files are published on issuer schedules (typically T+1); free-tier prices are delayed.

SEC. 07 — RISK DISCLOSURE
ETFs carry market risk, tracking error, and — for leveraged and inverse products — daily-reset decay that can produce losses even when the index view is right. Correlations shift, especially in stress. Read the full risk disclosure before using this pillar.
SOURCE DISCLOSURE: ETF analytics are computed from licensed US consolidated market data, publicly published issuer holdings files, public SEC filings and FRED macro series. Data may be delayed. Rotation and correlation readouts are statistical descriptions of past data, not predictions.
