Corrections
If a figure looks wrong, send the ticker, the page and what you expected. Errors are corrected on the page where they appeared, with the date. A fix to the method corrects every page at once.
Issuers
ETFIQ publishes the same fields for every fund in a category, from every issuer. It takes no payment for placement, a ranking position or leaving a fund out. If a figure taken from your disclosure is stale or misread, write and ETFIQ will check it against the source.
Journalists and researchers
The underlying files are public at Open data. The figures ETFIQ computes are free to use with attribution. Issuer data stays under its owner's terms. For a figure not in the files, or the method behind one, write and ask.
