IJR holdings
IJR reports 655 holdings and behaves like 356.1 equally weighted ones, computed from its SEC Form N-PORT filing for 2026-06-30. The fact sheet publishes the first number; this page computes the second, and traces it across 28 quarters of filings.
Measured concentration

What stands out
as of 2026-06-30The largest line in IJR's filing is not a stock but Blackrock Cash Funds, a short-term position at 2.08% of net assets. Ten companies are 7.46% of the fund; the other 645 share the rest. Among the 721 equity funds measured here, IJR behaves like 356.1 holdings against a median of 42.4 — 8.4 times the median. Across 28 quarterly filings IJR has held roughly steady since 2019-09-30 (413.1 then, 356.1 now). Between the 2026-03-31 and 2026-06-30 filings 33 positions were added and 36 dropped; 14.5% of the weight moved.

2Overlap with other funds

As filed, collateral included
5.45% collateralIJR's filing lists 656 positions including 5.45% of net assets in securities-lending cash collateral. Counted as filed the fund reads 173.5 effective holdings with a top ten of 12.4%; on its own investments — the figure above — it reads 356.1 with a top ten of 7.46%. The collateral is matched by a liability and is not a holding the fund chose; since 2026-09-18 every figure on this site sets it aside (methodology). Both numbers are in the data.

Who borrows IJR'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, $6.0bn was out to 30 borrowers, 5.41% of net assets. The largest, JP MORGAN SECURITIES LLC, held 15.4% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| JP MORGAN SECURITIES LLC | $927m | 15.4% |
| GOLDMAN SACHS INTERNATIONAL | $670m | 11.1% |
| MORGAN STANLEY & CO LLC | $644m | 10.7% |
| BofA Securities, Inc. | $614m | 10.2% |
| CITIGROUP GLOBAL MARKETS INC. | $575m | 9.6% |
Cash collateral reported against the loan: 5.45% of net assets, 100.7% 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 IJR has filed, with each borrower: IJR.json · all funds.

2026-03-31 → 2026-06-30606 positions became 603: 33 added (4.9% of the fund at the later date), 36 dropped (4.6% at the earlier date). Half the sum of all weight changes, a turnover proxy: 14.5%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

99.9% of IJR is carried at a quoted market price (fair-value level 1). Categories and levels are the filer's, from Form N-PORT; 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 $111.32B. Notional of an interest-rate or currency swap is not equity exposure.
| Swap counterparty | Notional | % of net assets |
|---|---|---|
| Goldman Sachs Bank USA | $28M | 0.03% |
| HSBC BANK PLC | $17M | 0.02% |
| JPMORGAN CHASE BANK, NATIONAL ASSOCIATION | $12M | 0.01% |
| Merrill Lynch International | $12M | 0.01% |
| BNP PARIBAS | $4M | 0% |
Financing leg as filed: the fund pays OVERNIGHT BANK FUNDING RATE + 0.379% on $72M of long swap notional . Issuers fill the spread field differently (some file the all-in rate), so compare within an issuer, not across.

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.
