BOND holdings

BOND reports 1,815 holdings and behaves like 83.2 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

This figure is not comparable with other funds

swap and futures notional is 89% of net assets: the fund's exposure is delivered by derivatives, and a count of its filed positions does not describe it. See the exposure section for what the notional is written on

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.

1,549 positions became 1,581: 190 added (31.4% of the fund at the later date), 158 dropped (23.9% at the earlier date). Half the sum of all weight changes, a turnover proxy: 32.3%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

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 $8.31B. Notional of an interest-rate or currency swap is not equity exposure.

Financing leg as filed: the fund pays Euribor 3 Month + 0% on $549M of long swap notional . Issuers fill the spread field differently (some file the all-in rate), so compare within an issuer, not across.
