## IWF and VONG: money in and out, side by side

In the three months to Oct 8, 2026, IWF, the only Russell 1000 Growth ETF counted all three months, lost $1.4bn .

Two bases on one page. IWF has daily figures: IWF from iShares. VONG has monthly figures only, from SEC Form N-PORT, which reports all of a fund’s share classes together, so VONG’s month includes the mutual fund classes of the same portfolio. VONG’s bars are months and sit beside the others’ days; its cells below print the latest month filed and no figure, and are not blank; the total column adds the daily funds only.

| 1 week · Oct 2 to Oct 8 | +$170m | monthly only · to May 2026 | +$170m |

| 3 months · Jul 9 to Oct 8 | −$1.4bn | monthly only · to May 2026 | −$1.4bn |
| Year to date | −$5.4bn | monthly only · to May 2026 | −$5.4bn |
| 1 year | +$7.0m | monthly only · to May 2026 | +$7.0m |

VONG’s latest filed month is May 2026, so its cells print that month and no figure: a month is never summed into a window or carried forward.
