Sep 2022 to Sep 2026, at least 64% of the book priced each quarter. Not audited fund performance. What this covers

Each quarter is priced from the date its SEC filing became public, not the quarter it describes, and weighted by position size. A 13F shows long US stock holdings only, so shorts, cash, options, and anything bought and sold between two filings are not in this line.
