Data sources

ETF Research aggregates information from several independent providers and public regulatory filings. We are grateful to these sources; their inclusion here does not imply any endorsement or affiliation.

• Tiingo — fund metadata and descriptions, intraday (real-time / delayed) quotes, adjusted end-of-day price history used for our return calculations, and news.
• Nasdaq — the ETF universe, real-time quote details, and fund summary statistics including net assets, 52-week range, average volume, and beta.
• Finnhub — a secondary quote source and additional company news.
• SEC EDGAR — the U.S. Securities and Exchange Commission’s public filing system, used for prospectus and registration links and portfolio (N-PORT) holdings.

Figures are aggregated automatically, may be delayed at least 20 minutes, and may be incomplete or contain errors. Always verify against a fund’s official prospectus and your broker before making any investment decision. See our disclaimers.
