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

as of 2026-06-30

Read this figure with the following in mind

5.5% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 173.5

The figure below is what the filing says, published unchanged. What it may not do is sit beside a plain long-only fund and be read as the same quantity. How comparability is decided.

What stands out

as of 2026-06-30

The 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.

Each sentence is read from the fund's own SEC filing; the class median is computed across the comparable equity funds on this site. Nothing here is a view on the fund.

As filed, collateral included

5.45% collateral

IJR'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

2026-06-30

The 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.

BorrowerOn loanShare 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.

Since the previous filing

2026-03-31 → 2026-06-30

606 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 2026-06-30

A 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.

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.
