Returns the fund reported
2019-09 – 2026-05Monthly total returns from Item B.5 of JPST's own filings, 81 months on record. Not computed here and not from a price feed.
Cross-checked against a series computed separately from prices: median difference 0.04 percentage points over 81 months, which is roughly the distributions. Every month with the filing it came from: JPST.json · all funds.
Who borrows JPST'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, $15m was out to 8 borrowers, 0.04% of net assets. The largest, PERSHING, LLC, held 31.9% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| PERSHING, LLC | $5m | 31.9% |
| BMO Capital Markets | $3m | 23.0% |
| BARCLAYS BANK PLC | $2m | 14.1% |
| BofA Securities, Inc. | $1m | 10.1% |
| BNP PARIBAS PRIME BROKERAGE INTERNATIONAL LIMITED | $1m | 9.0% |
Cash collateral reported against the loan: 0.04% of net assets, 103.6% 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 JPST has filed, with each borrower: JPST.json · all funds.

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 $38.41B. Notional of an interest-rate or currency swap is not equity exposure.
