Returns the fund reported
2019-07 – 2026-06Monthly total returns from Item B.5 of IVV's own filings, 84 months on record. Not computed here and not from a price feed.
Cross-checked against a series computed separately from prices: median difference 0.05 percentage points over 84 months, which is roughly the distributions. Every month with the filing it came from: IVV.json · all funds.
Who borrows IVV's shares
2026-06-30The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-06-30, $1.5bn was out to 21 borrowers, 0.17% of net assets. The largest, CITIGROUP GLOBAL MARKETS INC., held 24.7% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| CITIGROUP GLOBAL MARKETS INC. | $368m | 24.7% |
| JP MORGAN SECURITIES LLC | $259m | 17.4% |
| UBS AG | $167m | 11.2% |
| BNP PARIBAS PRIME BROKERAGE INTERNATIONAL LIMITED | $132m | 8.9% |
| MORGAN STANLEY & CO LLC | $130m | 8.7% |
Cash collateral reported against the loan: 0.17% of net assets, 101.5% of the amount lent. That is a floor on the collateral, not the whole of it — collateral the fund does not hold as a position is not in this filing, so a figure under 100% is not evidence of under-collateralisation. How that figure behaves across all funds. Every quarter IVV has filed, with each borrower: IVV.json · all funds.
Since the previous filing
2026-03-31 → 2026-06-30504 positions became 506: 11 added (0.9% of the fund at the later date), 9 dropped (0.5% at the earlier date). Half the sum of all weight changes, a turnover proxy: 8.8%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

Asset categories and pricing
as of 2026-06-3099.72% equity, 0.28% short-term investment as filed; 100.0% carried at a quoted market price (fair-value level 1). Categories and levels are the filer's; what a low level-1 share does and does not mean is in the measure's page.
Derivative exposure and counterparties
as of 2026-06-30A position count cannot describe a fund that uses derivatives, because a swap is filed at its unrealised gain, not its exposure. These are the notionals the fund itself reported, against net assets of $888.13B. Notional of an interest-rate or currency swap is not equity exposure.

Why 2,017 IWM Holdings Read as 33: Securities Lending in the Russell 2000 ETF
IWM, the iShares Russell 2000 ETF, files 2,017 holdings but our concentration measure read it as 33. The cause is a 17% cash-collateral position from securities lending, flagged in the filing itself; set it aside and the fund's own investments behave like about 840. Seventy-three funds on this site, including IJH, IJR, RSP, LQD and HYG, had the same problem. What we found, what we changed today, and what is still open.
