Indice de confiance des initiés

L'indice de confiance des initiés identifie les entreprises achetées par les initiés.

Il est le résultat d'un modèle quantitatif sophistiqué et multifactoriel qui identifie les entreprises présentant les niveaux les plus élevés de capitalisation d'initiés. Le modèle de notation utilise une combinaison du nombre net d'initiés ayant acheté des actions au cours des 90 derniers jours, du nombre total d'actions achetées en pourcentage du flottant et du nombre total d'actions détenues par les initiés. Le nombre varie de 0 à 100, les chiffres les plus élevés indiquant un niveau d'accumulation supérieur à celui de ses pairs, et 50 étant la moyenne.

Fréquence de mise à jour : Quotidienne

Voir Les meilleurs choix des initiés, qui fournit une liste des entreprises ayant la plus forte accumulation d'initiés.

Indice de confiance des dirigeants

L'indice de confiance des dirigeants identifie les entreprises dont les actions sont achetées par des dirigeants d'entreprise.

Par définition, les dirigeants d'entreprise sont des initiés, mais contrairement à d'autres initiés (actionnaires à 10 % et membres du conseil d'administration), les dirigeants travaillent quotidiennement pour l'entreprise et utilisent leur propre argent lorsqu'ils effectuent des opérations (les actionnaires à 10 % et les membres du conseil d'administration sont souvent des gestionnaires de fonds qui gèrent l'argent d'autrui). À ce titre, les opérations d'initiés réalisées par les dirigeants sont beaucoup plus significatives et doivent être traitées de manière appropriée.

Comme l'indice de confiance des initiés, l'indice de confiance des dirigeants est le résultat d'un modèle quantitatif sophistiqué et multifactoriel qui identifie les entreprises présentant les niveaux les plus élevés d'accumulation de dirigeants.

Fréquence de mise à jour : Quotidienne

Consultez la section Les meilleurs choix des initiés, qui fournit une liste des entreprises dont le sentiment des initiés est le plus élevé.

Principaux indicateurs des initiés

Cette carte montre comment l'entreprise se positionne par rapport à divers indicateurs d'initiés. La position en centile montre comment cette entreprise se situe par rapport aux autres entreprises sur les marchés américains. Une position plus élevée indique une meilleure situation.

Par exemple, il est généralement admis que les achats d'initiés sont un indicateur positif, de sorte que les entreprises dont les achats d'initiés sont plus nombreux se positionnent mieux que celles dont les achats d'initiés sont moins nombreux (ou même les ventes d'initiés).

Nombre net d'achats d'initiés (position)

-4 ( )

10898 out of 11305

Le nombre net d'initiés achetant est le nombre total d'initiés achetant moins le nombre total d'initiés vendant au cours des 90 derniers jours. La position en centile est indiquée ici (de 0 à 100%).

Pourcentage du flottant acheté par les initiés (position)

-0.005 %( )

9838 out of 11224

Le pourcentage du flottant acheté par les initiés est le nombre total d'actions achetées par les initiés moins le nombre total d'actions vendues par les initiés au cours des 90 derniers jours, divisé par le flottant total et multiplié par 100.

Graphique des opérations d'initiés

Les opérations d'initiés de MKS Inc. sont présentées dans le graphique suivant. Les initiés sont des dirigeants, des administrateurs ou des investisseurs importants dans une entreprise. En général, il est illégal pour les initiés d'effectuer des opérations d'initiés dans leur entreprise sur la base d'informations matérielles non publiques. Cela ne signifie pas qu'il est illégal pour eux d'effectuer toute transaction dans leurs propres entreprises. Toutefois, ils doivent déclarer toutes les transactions à la SEC au moyen d'un formulaire 4.

Liste d'initiés et indicateurs de rentabilité

Ce tableau présente la liste des initiés connus et est généré automatiquement à partir des dépôts communiqués à la SEC. Outre les noms, le titre le plus récent et la désignation du directeur, du dirigeant ou du propriétaire à 10 %, nous indiquons les dernières participations divulguées. En outre, lorsque cela est possible, nous indiquons les performances historiques des opérations d'initiés. La performance historique des transactions est une moyenne pondérée de la performance des opérations d'achat réelles sur le marché public effectuées par l'initié.
