MSTY 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: 1.55% at a quoted market price (level 1), one issuer country.

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.

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.

Monthly total returns from Item B.5 of MSTY's own filings, 21 months on record. Not computed here and not from a price feed.

Cross-checked against a series computed separately from prices: median difference — percentage points over 0 months, which is roughly the distributions. Every month with the filing it came from: MSTY.json · all funds.

8 positions became 8: 2 added (18.4% of the fund at the later date), 2 dropped (22.8% at the earlier date). Half the sum of all weight changes, a turnover proxy: 36.0%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of MSTY compared this way, as a feed: changes.xml · all funds: filings received.

New: TREASURY BILL (14.89%), TREASURY BILL (3.48%). Gone: TREASURY BILL (15.71%), US TREASURY N/B (7.03%).

1.6% of MSTY 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 $1.28B. 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 MSTY (4.6). Same filings, same arithmetic. Position in this list says nothing about which fund is better.
