Insider-Stimmungswert

Der Insider-Stimmungswert ermittelt die Unternehmen, die von Unternehmensinsidern gekauft werden.

Es ist das Ergebnis eines ausgeklügelten quantitativen Multifaktormodells, das die Unternehmen mit der höchsten Insiderakkumulation identifiziert. Das Scoring-Modell verwendet eine Kombination aus der Nettozahl der Insiderkäufe der letzten 90 Tage, der Gesamtzahl der gekauften Aktien als Prozentsatz des Streubesitzes und der Gesamtzahl der von Insidern gehaltenen Aktien. Die Zahl reicht von 0 bis 100, wobei höhere Zahlen ein höheres Maß an Insiderkäufen anzeigen als bei anderen Unternehmen und 50 den Durchschnitt darstellt.

Führungskräfte-Stimmungswert

Der Führungskräfte-Stimmungswert findet Unternehmen, die von Führungskräften des Unternehmens gekauft werden.

Per Definition sind Führungskräfte des Unternehmens Insider, aber im Gegensatz zu anderen Insidern (10%ige Aktionäre und Vorstandsmitglieder) arbeiten Führungskräfte täglich für das Unternehmen und verwenden beim Handel ihr eigenes Geld. (10%ige Aktionäre und Vorstandsmitglieder sind oft Fondsmanager, die das Geld anderer Leute verwalten.) Daher sind Insider-Geschäfte, die von Führungskräften getätigt werden, viel bedeutender und sollten entsprechend behandelt werden.

Wie der Insider-Stimmungswert ist auch der Führungskräfte-Stimmungswert das Ergebnis eines ausgeklügelten quantitativen Multifaktormodells, das die Unternehmen mit der höchsten Führungskräftekonzentration identifiziert.

Wichtige Insider-Kennzahlen

Diese Karte zeigt, wie das Unternehmen bei verschiedenen Insider-Kennzahlen abschneidet. Der Perzentil-Rang zeigt, wie dieses Unternehmen im Vergleich zu anderen Unternehmen auf den US-Märkten abschneidet. Höhere Ränge deuten auf eine bessere Situation hin.

Es ist beispielsweise allgemein anerkannt, dass Insiderkäufe ein positiver Indikator sind, so dass Unternehmen mit mehr Insiderkäufen besser abschneiden würden als Unternehmen mit weniger Insiderkäufen (oder sogar Insiderverkäufen).

Nettoanzahl der Insider, die kaufen (Rang)

2 ( )

239 out of 10951

Die Nettoanzahl der Insiderkäufe ist die Gesamtzahl der Insiderkäufe abzüglich der Gesamtzahl der Insiderverkäufe in den letzten 90 Tagen. Der Perzentilrang wird hier angezeigt (Bereich von 0 bis 100%).

Prozent des Streubesitzes von Insidern gekauft (Rang)

0.018% ( )

479 out of 10791

Prozent des von Insidern gekauften Streubesitzes ist die Gesamtzahl der von Insidern gekauften Aktien abzüglich der Gesamtzahl der von Insidern in den letzten 90 Tagen verkauften Aktien, geteilt durch den gesamten Streubesitz und multipliziert mit 100.

Diagramm zum Insiderhandel

CDW Corporation Insider-Trades sind in der folgenden Grafik dargestellt. Insider sind leitende Angestellte, Direktoren oder bedeutende Investoren in einem Unternehmen. Im Allgemeinen ist es für Insider illegal, auf der Grundlage von wesentlichen, nicht-öffentlichen Informationen mit Aktien ihrer Unternehmen zu handeln. Das bedeutet nicht, dass es für sie illegal ist, irgendwelche Geschäfte in ihren eigenen Unternehmen zu tätigen. Sie müssen jedoch alle Geschäfte der SEC über ein Formular 4 melden.

Kennzahlen zu Insiderlisten und Rentabilität

Diese Tabelle zeigt die Liste der bekannten Insider und wird automatisch aus den bei der SEC eingereichten Unterlagen erstellt. Zusätzlich zu den Namen, dem letzten Titel und der Bezeichnung als Direktor, leitender Angestellter oder 10%-iger Anteilseigner geben wir die zuletzt veröffentlichten Bestände an. Zusätzlich stellen wir, wenn möglich, die historische Handelsperformance für den Insider zur Verfügung. Die historische Handelsperformance ist ein gewichteter Durchschnitt der Performance tatsächlicher offener Kauftransaktionen, die von dem Insider getätigt wurden. Weitere Informationen zur Berechnung dieses Wertes finden Sie in diesem YouTube-Webinar.

Erfolgsbilanz der Insiderkäufe - Kurzfristige Gewinnanalyse

In diesem Abschnitt analysieren wir die Rentabilität jedes ungeplanten Insiderkaufs, der auf dem freien Markt in CDW / CDW Corporation getätigt wurde.

Diese Analyse bezieht sich auf ein Jahr nach jedem Handel, und die Ergebnisse sind theoretisch .
