How this is computed

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 Nov 11, 2026.
