What stands out

as of 2026-06-30

The largest line in SCHZ's filing is not a stock but State Street Institutional US Government Money Market Fund, a short-term position at 1.56% of net assets. Ten companies are 4.92% of the fund; the other 12,317 share the rest. Among the 192 bond funds measured here, SCHZ behaves like 807.8 holdings against a median of 236.4 — 3.4 times the median. Across 28 quarterly filings SCHZ has become less concentrated: it behaved like 500 at 2019-09-30 and 807.8 at 2026-06-30. Between the 2026-03-31 and 2026-06-30 filings 635 positions were added and 390 dropped; 10.0% 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 SCHZ's shares

2026-06-30

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-06-30, $15m was out to 10 borrowers, 0.14% of net assets. The largest, CITIGROUP GLOBAL MARKETS INC., held 33.6% of it.

BorrowerOn loanShare of the loan
CITIGROUP GLOBAL MARKETS INC. $5m 33.6%
JP MORGAN SECURITIES LLC $5m 30.8%
BofA Securities, Inc. $3m 18.8%
NOMURA SECURITIES INTERNATIONAL INC. $725,188 4.8%
BMO Capital Markets $653,685 4.4%

Cash collateral reported against the loan: 0.15% of net assets, 106% 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 SCHZ has filed, with each borrower: SCHZ.json · all funds.

Since the previous filing

2026-03-31 → 2026-06-30

12,081 positions became 12,326: 635 added (7.2% of the fund at the later date), 390 dropped (4.6% at the earlier date). Half the sum of all weight changes, a turnover proxy: 10.0%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of SCHZ compared this way, as a feed: changes.xml · all funds: filings received.
