El observatorio
Gestores destacados seleccionados — inversores en valor concentrados, activistas, quants y los grandes pasivos — observados trimestre a trimestre.
Las declaraciones pertenecen a las firmas, no a los individuos — escribimos "Berkshire Hathaway declaró…", nunca "Buffett compró…". Cada entrada indica la persona asociada y el tipo de cartera que revela el 13F.
