What stands out

as of 2026-05-31

The largest line in BBAG's filing is not a stock but JPMorgan U.S. Government Money Market Fund, Class IM, a short-term position at 2.26% of net assets. Ten companies are 11.44% of the fund; the other 1,800 share the rest. Among the 192 bond funds measured here, BBAG behaves like 286.5 holdings against a median of 236.4 — close to the median. Across 27 quarterly filings BBAG has become less concentrated: it behaved like 174.8 at 2019-11-30 and 286.5 at 2026-05-31. Between the 2026-02-28 and 2026-05-31 filings 180 positions were added and 122 dropped; 10.2% of the weight moved.

Each sentence is read from the fund's own SEC filing; the class median is computed across the comparable bond funds on this site. Nothing here is a view on the fund.

Who borrows BBAG's shares

2025-08-31

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2025-08-31, $2m was out to 6 borrowers, 0.13% of net assets. The largest, BARCLAYS BANK PLC, held 47% of it.

BorrowerOn loanShare of the loan
BARCLAYS BANK PLC $781,262 47.0%
NOMURA SECURITIES INTERNATIONAL INC. $440,743 26.5%
BMO Capital Markets $157,158 9.5%
BofA Securities, Inc. $151,969 9.1%
BARCLAYS CAPITAL INC. $76,518 4.6%

Cash collateral reported against the loan: 0.13% of net assets, 99.7% 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 BBAG has filed, with each borrower: BBAG.json · all funds.

Since the previous filing

2026-02-28 → 2026-05-31

1,749 positions became 1,807: 180 added (6.3% of the fund at the later date), 122 dropped (4.9% at the earlier date). Half the sum of all weight changes, a turnover proxy: 10.2%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of BBAG compared this way, as a feed: changes.xml · all funds: filings received.
