Data & sources | FundOverlapCheck

Bundled dataset

Top reported equity holdings for 7 widely held U.S. ETFs (VOO, VTI, QQQ, VGT, VYM, VUG, VTV), taken from each fund's most recent SEC Form N-PORT-P monthly portfolio report as filed with EDGAR. Weights are the filer-reported percent of net assets (pctVal) for each security; sector labels are a manual GICS-style assignment added for this site, since N-PORT does not carry a standardized sector field. N-PORT is filed with a reporting lag, so the reference date on each row is the fund's own report period, not today's date.

Classification: reviewed. Records: 84. Reference date: 2026-04-30. License or use basis: U.S. government record (SEC Form N-PORT-P), public domain; no restriction on republishing filed facts..

Data in this build is a snapshot, not a live connection. Your browser does not poll a market-data API. Importing a file changes this tab only. Public updates require the publisher to refresh, review, rebuild, and redeploy the snapshot.

Corrections and publication standards

Every publicly distributed observation should retain its source URL, period, units, and review trail. Buyback executions must match the same trading-volume coverage. Event-option quotes must precede the event. Holdings should retain their actual snapshot dates. Never refresh a timestamp without refreshing the underlying evidence.
