The Q4 2023 13F season
← Every quarter98 of the 101 managers we track have filed a Q4 2023 13F. Between them they opened 746 new positions and sold out of 778, across 2,452 names.
A 13F is due within 45 days of the quarter's end — 2024-02-14 for Q4 2023. Books still arrive for weeks after it; the numbers above cover the managers who have filed.
Each manager is compared against their OWN previous filed book, never the calendar's previous quarter — a manager who skipped a quarter would otherwise report every line they hold as new. 4 positions were reported under a different identifier than in the manager's previous book (an ADR line becoming an ordinary one, a CUSIP re-issue); they are counted as held, and as neither a new position nor an exit. 267 lines this quarter carry no ticker in the register; they are counted, and they cannot appear on the two name boards.
