Returns the fund reported
2019-07 – 2026-06Monthly total returns from Item B.5 of SPTL'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 0.08 percentage points over 84 months, which is roughly the distributions. Every month with the filing it came from: SPTL.json · all funds.
Who borrows SPTL's shares
2026-03-31The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-03-31, $38m was out to 2 borrowers, 0.36% of net assets. The largest, BARCLAYS CAPITAL INC., held 99.4% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| BARCLAYS CAPITAL INC. | $38m | 99.4% |
| BofA Securities, Inc. | $240,501 | 0.6% |
Cash collateral reported against the loan: 0.09% of net assets, 24.9% 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 SPTL has filed, with each borrower: SPTL.json · all funds.
Since the previous filing
2026-03-31 → 2026-06-3098 positions became 100: 2 added (1.7% 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.
