IWP holdings
IWP reports 269 holdings and behaves like 104.8 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

3.7% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 91.7
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
3.7% collateralIWP's filing lists 270 positions including 3.7% of net assets in securities-lending cash collateral. Counted as filed the fund reads 91.7 effective holdings with a top ten of 21.85%; on its own investments — the figure above — it reads 104.8 with a top ten of 19.71%. 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 IWP'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, $833m was out to 26 borrowers, 3.86% of net assets. The largest, JP MORGAN SECURITIES LLC, held 22.9% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| JP MORGAN SECURITIES LLC | $191m | 22.9% |
| MORGAN STANLEY & CO LLC | $143m | 17.2% |
| GOLDMAN SACHS INTERNATIONAL | $113m | 13.5% |
| UBS AG | $62m | 7.5% |
| BofA Securities, Inc. | $58m | 7.0% |
Cash collateral reported against the loan: 3.70% of net assets, 95.8% 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 IWP has filed, with each borrower: IWP.json · all funds.

Asset categories and pricing
as of 2026-06-3096.32% equity, 3.67% 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 $21.57B. Notional of an interest-rate or currency swap is not equity exposure.
