Where a paper makes a claim ETFIQ’s data can test, "The ETFIQ take" states the paper’s figure and ETFIQ’s figure side by side, dated, with links to the fund, desk or research page. A summary that fails a check is held, never published. How the library is made --- Source: ETFIQ, independent ETF data. Recomputed nightly from public filings and prices.
