IYZ holdings

IYZ reports 25 holdings and behaves like 10.9 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

8.7% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 10.1

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.

As filed, collateral included

8.67% collateral

IYZ's filing lists 26 positions including 8.67% of net assets in securities-lending cash collateral. Counted as filed the fund reads 10.1 effective holdings with a top ten of 74.97%; on its own investments — the figure above — it reads 10.9 with a top ten of 69.49%. 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 IYZ'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, $119m was out to 8 borrowers, 9.53% of net assets. The largest, BofA Securities, Inc., held 34.1% of it.

BorrowerOn loanShare of the loan
BofA Securities, Inc. $40m 34.1%
JP MORGAN SECURITIES LLC $33m 27.7%
GOLDMAN SACHS & CO. $21m 18.0%
MORGAN STANLEY & CO LLC $16m 13.7%
BNP PARIBAS PRIME BROKERAGE INTERNATIONAL LIMITED $6m 4.7%

Cash collateral reported against the loan: 8.67% of net assets, 91% 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 IYZ has filed, with each borrower: IYZ.json · all funds.

Since the previous filing

2026-03-31 → 2026-06-30

23 positions became 25: 5 added (12.9% of the fund at the later date), 3 dropped (3.3% at the earlier date). Half the sum of all weight changes, a turnover proxy: 23.4%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

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 $1.24B. Notional of an interest-rate or currency swap is not equity exposure.
