Source: NPORT-P filings, via EDGAR. Positions arrive by CUSIP, and only a CUSIP verified against a ticker is kept — so this is what we could match, not everything the fund holds, and the matched value is therefore below the fund's own size. A balance is shares where the filing says `NS` and a principal amount where it says `PA`, which is why it is not labelled shares in both cases.
