VXF holdings

VXF reports 3,371 holdings and behaves like 582.2 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

3.6% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 329.2

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

3.63% collateral

VXF's filing lists 3,372 positions including 3.63% of net assets in securities-lending cash collateral. Counted as filed the fund reads 329.2 effective holdings with a top ten of 10.71%; on its own investments — the figure above — it reads 582.2 with a top ten of 7.55%. 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 VXF'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, $3.6bn was out to 33 borrowers, 3.67% of net assets. The largest, GOLDMAN SACHS & CO., held 14.4% of it.

BorrowerOn loanShare of the loan
GOLDMAN SACHS & CO. $518m 14.4%
BofA Securities, Inc. $486m 13.6%
CITIGROUP GLOBAL MARKETS INC. $458m 12.8%
Wells Fargo Securities LLC $421m 11.7%
MORGAN STANLEY & CO LLC $352m 9.8%

Cash collateral reported against the loan: 3.63% of net assets, 98.9% 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 VXF has filed, with each borrower: VXF.json · all funds.

Since the previous filing

2026-03-31 → 2026-06-30

3,318 positions became 3,321: 132 added (2.3% of the fund at the later date), 129 dropped (1.8% at the earlier date). Half the sum of all weight changes, a turnover proxy: 12.8%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of VXF compared this way, as a feed: changes.xml · all funds: filings received.

Asset categories and pricing

96.38% equity, 3.62% short-term investment as filed; 100.0% carried at a quoted market price (fair-value level 1). Categories and levels are the filer's; what a low level-1 share does and does not mean is in the measure's page.

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 $97.70B. Notional of an interest-rate or currency swap is not equity exposure.

100%Sum, % of net assets

Goldman Sachs International$6M0.01%

Financing leg as filed: the fund pays OBFR01 + 0% on $27M of long swap notional . Issuers fill the spread field differently (some file the all-in rate), so compare within an issuer, not across.

  • Why 2,017 IWM Holdings Read as 33: Securities Lending in the Russell 2000 ETF

    IWM, the iShares Russell 2000 ETF, files 2,017 holdings but our concentration measure read it as 33. The cause is a 17% cash-collateral position from securities lending, flagged in the filing itself; set it aside and the fund's own investments behave like about 840. Seventy-three funds on this site, including IJH, IJR, RSP, LQD and HYG, had the same problem. What we found, what we changed today, and what is still open.
