SYSB holdings

Computed by this site from the fund's SEC Form N-PORT filing; what the measure does not tell you · every fund in one table · hold it with other funds? X-ray the mix. Pricing: 14.23% at a quoted market price (level 1), 17 issuer countries.

The largest line in SYSB's filing is not a stock but BlackRock Cash Funds: Treasury, SL Agency Shares, a short-term position at 7.81% of net assets. Ten companies are 26.34% of the fund; the other 828 share the rest. Among the 192 bond funds measured here, SYSB behaves like 79 holdings against a median of 236.4 — 3.0 times more concentrated than the median. Across 27 quarterly filings SYSB has become more concentrated: it behaved like 164.2 at 2019-10-31 and 83.1 at 2026-04-30. Between the 2026-01-31 and 2026-04-30 filings 145 positions were added and 180 dropped; 33.1% 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.

Between 2019-10-31 and 2026-04-30, SYSB went from behaving like 164.2 equally weighted positions to 83.1 — 49% fewer, while its top ten went from 19.04% to 26.09% of net assets. Read across the funds on the concentration-over-time table.

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.

SYSB's filing lists 839 positions including 7.52% of net assets in securities-lending cash collateral. Counted as filed the fund reads 50.5 effective holdings with a top ten of 33.83%; on its own investments — the figure above — it reads 79 with a top ten of 26.34%. 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.

Monthly total returns from Item B.5 of SYSB's own filings, 81 months on record. Not computed here and not from a price feed.

Cross-checked against a series computed separately from prices: median difference 0.09 percentage points over 81 months, which is roughly the distributions. Every month with the filing it came from: SYSB.json · all funds.

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-07-31, $84m was out to 25 borrowers. The largest, TD Securities (USA) LLC, Cowen, held 27.2% of it.

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. What the collateral figure can and cannot show. Every quarter SYSB has filed, with each borrower: SYSB.json · all funds.

892 positions became 857: 145 added (23.2% of the fund at the later date), 180 dropped (19.4% at the earlier date). Half the sum of all weight changes, a turnover proxy: 33.1%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of SYSB compared this way, as a feed: changes.xml · all funds: filings received.

14.2% of SYSB is carried at a quoted market price (fair-value level 1). Categories and levels are the filer's, from Form N-PORT; what a low level-1 share does and does not mean is in the measure's page.

A position count cannot describe a fund that uses derivatives, because a swap is filed at its unrealised gain, not its exposure. These are the notionals the fund itself reported, against net assets of $1.02B. Notional of an interest-rate or currency swap is not equity exposure.

Every measured debt fund lined up by how many holdings it behaves like; these sit either side of SYSB (79). Same filings, same arithmetic. Position in this list says nothing about which fund is better.
