Source: quarterly NPORT-P filings, via EDGAR. Positions arrive by CUSIP; each one here has been confirmed against OpenFIGI rather than matched by name. NPORT covers mutual funds, ETFs and closed-end funds alike and does not distinguish them, and positions are as of quarter end — a fund may have sold out entirely since. The summed value counts each filing once, so two share classes of the same fund appear twice.
