IBDZ holdings

IBDZ reports 375 holdings and behaves like 283.2 equally weighted ones, computed from its SEC Form N-PORT filing for 2026-07-31. The fact sheet publishes the first number; this page computes the second, and traces it across 8 quarters of filings.

Measured concentration

as of 2026-07-31

Read this figure with the following in mind

9.8% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 76.5

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.

One row per filed reporting period, newest first, read from EDGAR. Quarterly because that is the public filing cadence. Rows marked * are published but held out of the comparison above; the methodology page says when and why.

As filed, collateral included

9.82% collateral

IBDZ's filing lists 376 positions including 9.82% of net assets in securities-lending cash collateral. Counted as filed the fund reads 76.5 effective holdings with a top ten of 17.39%; on its own investments — the figure above — it reads 283.2 with a top ten of 8.35%. 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.

The filing reports no cash collateral position against this loan. Collateral taken in a form the fund does not hold as a position does not appear in N-PORT, so this is silence rather than absence.

Since the previous filing

2026-01-31 → 2026-04-30

373 positions became 372: 0 added (0.0% of the fund at the later date), 1 dropped (0.2% at the earlier date). Half the sum of all weight changes, a turnover proxy: 3.9%.
