XSD holdings
XSD reports 50 holdings and behaves like 43.4 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

As filed, collateral included
7.94% collateralXSD's filing lists 51 positions including 7.94% of net assets in securities-lending cash collateral. Counted as filed the fund reads 34.1 effective holdings with a top ten of 34.46%; on its own investments — the figure above — it reads 43.4 with a top ten of 29.01%. 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 XSD'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, $471m was out to 21 borrowers, 13.56% of net assets. The largest, BARCLAYS BANK PLC, held 35.5% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| BARCLAYS BANK PLC | $167m | 35.5% |
| BofA Securities, Inc. | $100m | 21.1% |
| MORGAN STANLEY & CO LLC | $39m | 8.2% |
| BNP PARIBAS SECURITIES CORP | $35m | 7.4% |
| NOMURA SECURITIES INTERNATIONAL INC. | $32m | 6.9% |
Cash collateral reported against the loan: 7.94% of net assets, 58.6% 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 XSD has filed, with each borrower: XSD.json · all funds.
Since the previous filing
2026-03-31 → 2026-06-3044 positions became 48: 4 added (6.0% 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: 15.4%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.
