Terms of Service

What OverlapCheck is

OverlapCheck provides informational analysis of publicly available financial data: ETF holdings from official issuer files and SEC filings. The free tools are provided as-is, for everyone, without an account.

Not investment advice

Nothing on this site is investment advice, a recommendation, or an offer to buy or sell any security. Metrics like fund overlap, max pain, and gamma exposure are positioning context derived from public data under simplifying assumptions - they are not predictions. Do your own research; consider consulting a licensed financial advisor before making investment decisions.

Data accuracy

We compute from official sources and re-check them nightly, but issuers publish on different schedules and errors can occur upstream or in our processing. The data is provided without warranty of accuracy, completeness, or timeliness. Our methodology documents exactly how each number is computed.

Holdings watch (free email alerts)

The holdings watch is a free service for manually entered ETF tickers. You give us an email address and a list of supported ETFs; we record each fund's current holdings date and email you when a fund in your list publishes new holdings, with a link that recalculates the overlap on the new data. There is no charge, no account, and no card.

You can stop at any time by replying “stop” to any email or contacting info@overlapcheck.com. Stopping deletes the saved list.

The holdings watch does not connect to a brokerage account, is not real-time, and produces informational analysis rather than trading signals or recommendations. Delivery timing is best-effort and depends on when fund issuers publish updated holdings. Funds outside the supported universe are not watched.

Before 2026-09-13 OverlapCheck sold an annual Portfolio Review + Monitoring service. It is no longer offered. Anyone who purchased it continues to receive it under the terms shown at purchase, and can cancel or ask for a refund at info@overlapcheck.com.

Acceptable use

Don't abuse the service: no scraping at disruptive rates, no attempting to disrupt the site, no misrepresenting OverlapCheck content as your own or as financial advice from us.

Our content and social media

OverlapCheck publishes derived data and commentary on this site and on social platforms (including X and TikTok). You may share and quote it with attribution. It remains informational content, not advice, wherever it appears.

Changes and contact

We may update these terms; the date above reflects the latest revision. Questions: info@overlapcheck.com.
