How this is computed
Percentages are of net assets at the start of each window. Numbers are net: money in less money out. Checked against the filing: The month’s daily sum and the filing’s B.6 number agree within rounding or, where the filing’s is larger, within rounding plus the fund’s creation and redemption fees. The full rule is in the fund’s flows file. Every day and month ETFIQ holds for IWB, back to Jul 2019, is in its flows file.
