Who borrows UPRO's shares
2026-05-31The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-05-31, $555,286 was out to 9 borrowers, 0.01% of net assets. The largest, MORGAN STANLEY & CO LLC, held 56.1% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| MORGAN STANLEY & CO LLC | $311,645 | 56.1% |
| GOLDMAN SACHS & CO. | $100,392 | 18.1% |
| Wells Fargo Securities LLC | $60,632 | 10.9% |
| JP MORGAN SECURITIES LLC | $39,416 | 7.1% |
| UBS AG | $17,576 | 3.2% |
Cash collateral reported against the loan: 0.01% of net assets, 99.9% 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 UPRO has filed, with each borrower: UPRO.json · all funds.
Since the previous filing
2026-02-28 → 2026-05-31507 positions became 510: 11 added (5.6% of the fund at the later date), 8 dropped (4.5% at the earlier date). Half the sum of all weight changes, a turnover proxy: 23.9%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

70.8% of UPRO 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 2026-05-31A 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 $5.55B. Notional of an interest-rate or currency swap is not equity exposure.
| Swap counterparty | Notional | % of net assets |
|---|---|---|
| BNP PARIBAS | $1.99B | 35.95% |
| Barclays Bank plc | $1.98B | 35.68% |
| Bank of America NA | $1.96B | 35.27% |
| UBS AG | $1.87B | 33.63% |

| Morgan Stanley & Co. International plc | $365M | 6.59% |
| Wells Fargo Bank NA | $213M | 3.85% |
Financing leg as filed: the fund pays FEDL01 + 0.922% on $13.43B of long swap notional . Issuers fill the spread field differently (some file the all-in rate), so compare within an issuer, not across.
