BYLD holdings

BYLD reports 13 holdings and behaves like 9.4 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 27 quarters of filings.

Measured concentration

as of 2026-07-31

Read this figure with the following in mind

76.8% of net assets carries no asset category in the filing

30.1% of net assets is securities-lending cash collateral, excluded from the figure; counted as filed the fund would read 5.1

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.

What stands out

as of 2026-07-31

Across 27 quarterly filings BYLD has become less concentrated: it behaved like 6 at 2019-10-31 and 8.9 at 2026-04-30.

As filed, collateral included

30.08% collateral

BYLD's filing lists 14 positions including 30.08% of net assets in securities-lending cash collateral. Counted as filed the fund reads 5.1 effective holdings with a top ten of 120.75%; on its own investments — the figure above — it reads 9.4 with a top ten of 94.84%. 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

12 positions became 12: 0 added (0.0% 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: 0.3%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of BYLD compared this way, as a feed: changes.xml · all funds: filings received.
