OPEN THE PORTFOLIO TRACKER →EDITORIAL · NOT INVESTMENT ADVICE. Source: SEC EDGAR Form 13F-HR, filed 45 days after quarter end. 13F covers US-listed long equity and options positions only — it excludes shorts, cash, credit, foreign listings and derivatives held outside the reporting scope, so it is a partial view of any manager's book, and it is always at least six weeks stale by the time it is public.
