Returns the fund reported
2019-07 – 2026-06Monthly total returns from Item B.5 of IYR'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: IYR.json · all funds.
Who borrows IYR'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, $608,578 was out to 1 borrower, 0.01% of net assets.
| Borrower | On loan | Share of the loan |
|---|---|---|
| VIRTU AMERICAS, LLC | $608,578 | 100.0% |
Cash collateral reported against the loan: 0.01% of net assets, 76.8% 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 IYR has filed, with each borrower: IYR.json · all funds.
Since the previous filing
2026-03-31 → 2026-06-3062 positions became 62: 0 added (0.0% of the fund at the later date), 0 dropped (0.0% at the earlier date). Half the sum of all weight changes, a turnover proxy: 3.8%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

Asset categories and pricing
as of 2026-06-3099.84% equity, 0.16% 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 $4.67B. Notional of an interest-rate or currency swap is not equity exposure.
