VB holdings

VB reports 1,316 holdings and behaves like 689.3 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 of 2026-06-30

Read this figure with the following in mind

1.5% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 596.7

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.

As filed, collateral included

1.5% collateral

VB's filing lists 1,317 positions including 1.5% of net assets in securities-lending cash collateral. Counted as filed the fund reads 596.7 effective holdings with a top ten of 5.47%; on its own investments — the figure above — it reads 689.3 with a top ten of 4.33%. 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 VB's shares

2026-06-30

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-06-30, $2.9bn was out to 33 borrowers, 1.55% of net assets. The largest, BofA Securities, Inc., held 19.4% of it.

BorrowerOn loanShare of the loan
BofA Securities, Inc. $567m 19.4%
GOLDMAN SACHS & CO. $490m 16.8%
MORGAN STANLEY & CO LLC $325m 11.1%
Wells Fargo Securities LLC $298m 10.2%
BARCLAYS BANK PLC $230m 7.9%

Cash collateral reported against the loan: 1.50% of net assets, 97% 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 VB has filed, with each borrower: VB.json · all funds.

Since the previous filing

2026-03-31 → 2026-06-30

1,310 positions became 1,308: 44 added (2.5% of the fund at the later date), 46 dropped (3.3% at the earlier date). Half the sum of all weight changes, a turnover proxy: 12.3%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of VB compared this way, as a feed: changes.xml · all funds: filings received.

Derivative exposure and counterparties

as of 2026-06-30

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 $188.70B. Notional of an interest-rate or currency swap is not equity exposure.

Goldman Sachs International$3M0%

Financing leg as filed: the fund pays OBFR01 + 0% on $56M of long swap notional . Issuers fill the spread field differently (some file the all-in rate), so compare within an issuer, not across.
