How are these flows measured?
A flow here is an ETF's net creations or redemptions of its own shares, in dollars. It is read from the ETF's holdings: each of the 625 US ETFs read every weekday night from its issuer's own file (Global X, Invesco, SPDR, Vanguard, iShares) is compared with its previous file. The value of what it bought less what it sold, and its own growth on its net assets, measure the same flow twice; it is published when the two agree within 10%, as their mean. On this close 57 ETFs were not measured: their two measures disagreed, as they do on a rebalance or a corporate action.
Each flow is dated at the market close of the file whose holdings changed, the day the creation reached the portfolio. Read from the holdings, it is unaffected by a split of the ETF's shares or by a distribution. The Vanguard ETFs that are a share class of a mutual fund (VOO, VTI) are not counted, since their files hold the whole fund. Every step is on how the numbers are produced.
