Methodology

The ETF universe

We enumerate the complete list of U.S.-listed exchange-traded funds and refresh it regularly so newly launched funds appear and delisted ones drop off. Each fund gets its own page at /etf/<TICKER>.

Quotes

Prices are real-time where the data provider marks them as such, and otherwise delayed by at least 20 minutes. Each fund page labels whether its quote is real-time or delayed and shows the quote timestamp. Quotes are cached briefly and refreshed when a page is viewed.

Performance

Trailing returns (1 month, 3 months, 6 months, year-to-date, 1, 3, and 5 years) are total returns computed from adjusted closing prices, which account for distributions and splits. Returns are point-to-point using the most recent close versus the close on (or just before) the start of each window.

Fund classification

We group funds into browsable sectors and themes (technology, healthcare, bonds, dividends, gold and commodities, international, leveraged/inverse, and more) using a rules-based classifier applied to each fund’s name. This is a convenience for browsing and is not a regulatory or issuer classification.

Holdings, fees, and prospectus

Net assets, expense ratios, holdings, and prospectus links are drawn from fund-stat providers and public SEC filings (including N-PORT portfolio filings and registration documents). Holdings and fees can lag the fund’s own latest disclosures; always confirm against the official prospectus.
