Insider-stemningsscore
Insider Sentiment Score viser, at virksomhederne bliver købt af virksomheders insidere.
Det er resultatet af en sofistikeret, multi-faktor kvantitativ model, der identificerer virksomheder med de højeste niveauer af insider-akkumulering. Scoringsmodellen bruger en kombination af nettoantallet af insidere, der har købt de foregående 90 dage, det samlede antal aktier købt som en procentdel af float og det samlede antal aktier ejet af insidere. Tallet går fra 0 til 100, hvor højere tal indikerer et højere niveau af akkumulering for sine jævnaldrende, og 50 er gennemsnittet.

Officers sentiment score
Officer Sentiment Score finder virksomheder, der bliver købt af Corporate Officers.
Per definition er Corporate Officers Corporate Insiders, men i modsætning til nogle af de andre Insiders (10 % aktionærer og bestyrelsesmedlemmer), arbejder officerer for virksomheden på daglig basis, og de bruger deres egne penge, når de handler . (10 % aktionærer og bestyrelsesmedlemmer er ofte fondsforvaltere, der administrerer andres penge.) Som sådan er insiderhandler foretaget af embedsmænd meget mere betydningsfulde og bør behandles passende.
Ligesom Insider Sentiment Score er Officer Sentiment Score resultatet af en sofistikeret, multi-faktor kvantitativ model, der identificerer virksomheder med de højeste niveauer af officerakkumulering.

Nøgle Insider Metrics
Dette kort viser, hvordan virksomheden rangerer langs forskellige insider-metrics. Percentilrangen viser, hvordan denne virksomhed sammenligner sig med andre virksomheder på de amerikanske markeder. Højere placeringer er tegn på bedre situationer.
For eksempel er det generelt accepteret, at insider-køb er en positiv indikator, så virksomheder med flere insider-køb vil rangere højere end virksomheder med mindre insider-køb (eller endda insider-salg).
Insiderhandelsdiagram
Koss Corporation insiderhandler er vist i følgende diagram. Insidere er embedsmænd, direktører eller betydelige investorer i en virksomhed. Generelt er det generelt ulovligt for insidere at foretage handler i deres virksomheder baseret på væsentlige, ikke-offentlige oplysninger. Dette betyder ikke, at det er ulovligt for dem at handle i deres egne virksomheder. De skal dog rapportere alle handler til SEC via en formular 4.
Insiderliste og lønsomhedsmålinger
Denne tabel viser listen over kendte insidere og genereres automatisk fra arkiveringer, der er videregivet til SEC. Ud over navnene, den seneste titel og direktør, officer eller 10 % ejerbetegnelse giver vi de seneste offentliggjorte besiddelser. Derudover giver vi, når det er muligt, den historiske handelspræstation for insideren. Den historiske handelspræstation er et vægtet gennemsnit af præstationen af faktiske købstransaktioner på det åbne marked foretaget af insideren. For mere information om, hvordan dette beregnes, se dette YouTube-webinar.
