Largest 50 of 750 shown; the full ranked, searchable register is at boothcheck.com/holders/TTD. Related filers are grouped using the filings' own included-manager declarations. Historically, several managers opening new positions in the same quarter said almost nothing about the quarter that followed (59,118 cases since 2013). A filed record, not a forecast. Nothing here is investment advice.
