The 15 largest of 463 positions in FSTB's Form N-PORT, weight as a share of net assets, securities-lending collateral excluded. Every position, every quarter: FSTB.csv.gz.

Share of FSTB's own investments by the issuer country the filer reported (incorporation, not revenue). Each country links to every fund that holds it.

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2022-02-28, $56m was out to 2 borrowers, 1.85% of net assets. The largest, NOMURA SECURITIES INTERNATIONAL INC., held 66.4% of it.

Cash collateral reported against the loan: 1.89% of net assets, 101.9% 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 FSTB has filed, with each borrower: FSTB.json · all funds.

463 positions became 462: 52 added (18.8% of the fund at the later date), 53 dropped (10.6% at the earlier date). Half the sum of all weight changes, a turnover proxy: 22.9%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of FSTB compared this way, as a feed: changes.xml · all funds: filings received.

0.1% of FSTB is carried at a quoted market price (fair-value level 1); 0.1% at level 3, priced from the filer's own inputs. 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 $2.60B. Notional of an interest-rate or currency swap is not equity exposure.
