As filed, collateral included
10.46% collateralHYBB's filing lists 1,073 positions including 10.46% of net assets in securities-lending cash collateral. Counted as filed the fund reads 81.5 effective holdings with a top ten of 14.62%; on its own investments — the figure above — it reads 729.1 with a top ten of 4.6%. 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.
