UPRO holdings

UPRO reports 523 holdings and behaves like 14.3 equally weighted ones, computed from its SEC Form N-PORT filing for 2026-05-31. The fact sheet publishes the first number; this page computes the second, and traces it across 27 quarters of filings.

Measured concentration

23.9% of net assets carries no asset category in the filing

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.

Who borrows UPRO's shares

2026-05-31

The 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.

BorrowerOn loanShare 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 → 2026-05-31

507 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 2026-05-31

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 $5.55B. Notional of an interest-rate or currency swap is not equity exposure.
