13F-filings
Wat de grote beleggers bezitten
Elk kwartaal zijn de grootste hedgefondsen en family offices verplicht om Form 13F-HR bij de SEC in te dienen, met daarin hun Amerikaanse aandelenposities. Dit zijn de 15 die wij het nauwst volgen. Klik op een naam voor hun laatste top-20-posities.
13F-filings tonen de posities per kwartaaleinde en worden binnen 45 dagen ingediend — ze laten zien wat de grote beleggers BEZATEN, niet wat ze NU bezitten.

Waarom 13F-filings ertoe doen
Fondsen die meer dan $100M aan Amerikaanse aandelen beheren, moeten elke 90 dagen hun longposities openbaar maken. Een 13F zegt op zichzelf niet wanneer een fonds kocht of verkocht, alleen wat ze aan het kwartaaleinde aanhielden. Maar overlap tussen fondsen op small-cap- en pre-pop-namen brengt vaak dezelfde setup naar boven die wij in ons onderzoek zoeken.
