How this is computed

N-PORT months: money in is sales plus reinvestments; money out is redemptions. Months summed from daily data: money in adds the days money came in; money out adds the days it went out.

N-PORT months are the filed sales plus reinvestments less redemptions. Later months add up the daily data; the Source column names any missing day.

Source: ETFIQ, from the fund’s daily share counts and net asset values, and its SEC N-PORT filings. Data as of Oct 23, 2026.
