Insider Sentiment Score
Insider sentiment score hittar de företag som köps av foretagsinsynspersoner.
Det är resultatet av en sofistikerad, kvantitativ multifaktormodell som identifierar företag med de högsta nivåerna av insiderackumulation. Poängmodellen använder en kombination av nettoantalet insiders som köpt de föregående 90 dagarna, det totala antalet aktier som köpts i procent av aktiekapitalet och det totala antalet aktier som ägs av insiders. Siffran sträcker sig från 0 till 100, med högre siffror som indikerar en högre nivå av ackumulering för sina kamrater, och 50 är genomsnittet.

Office Sentiment Score
Officersentiment Score hittar företag som köps av Corporate Officers.
Per definition Corporate Officers är Corporate Insiders, men till skillnad från vissa av de andra Insiders (10 % aktieägare och styrelseledamöter), arbetar ämbetsmän för företaget dagligen och de använder sina egna pengar när de handlar . (10 % aktieägare och styrelseledamöter är ofta fondförvaltare som förvaltar andras pengar.) Som sådan är insideraffärer som görs av tjänstemän mycket mer betydelsefulla och bör behandlas på lämpligt sätt.
Liksom Insider Sentiment Score är Officer Sentiment Score resultatet av en sofistikerad, kvantitativ multifaktormodell som identifierar företag med de högsta nivåerna av officersackumulering.

Viktiga insidernyckeltal
Denna kort visar hur företaget rankas längs olika insidernyckeltal. Procenttilrankningen visar hur detta företag jämförs med andra företag på USA-marknaden. Högre rankingar indikerar bättre situationer.
Till exempel anses det allmänt att insiderköp är en positiv indikator, så företag med mer insiderköp skulle rankas högre än företag med mindre insiderköp (eller til och med insiderförsäljning).
Procent av flytande köpta av insiders (ranking)
-0.053 %( )
10412 out of 11224Procentandelen av aktier köpta av insiders är det totala antalet aktier som köpts av insiders minus det totala antalet aktier som sålts av insiders under de senaste 90 dagarna, dividerat med det totala antalet aktier och multiplicerat med 100.
Insiderhandelsdiagram
Verastem, Inc. insideraffärer visas i följande diagram. Insiders är tjänstemän, styrelseledamöter eller betydande investerare i ett företag. I allmänhet är det i allmänhet olagligt för insiders att göra affärer i sina företag baserat på väsentlig, icke-offentlig information. Detta betyder inte att det är olagligt för dem att göra några affärer i sina egna företag. De måste dock rapportera alla affärer till SEC via ett formulär 4.
Insiderlista och lönsamhetsstatistik
Den här tabellen visar listan över kända insiders och genereras automatiskt från anmälningar som avslöjas till SEC. Förutom namnen, den senaste titeln och direktören, tjänstemannen eller ägarbeteckningen på 10 %, tillhandahåller vi de senaste avslöjade innehaven. Dessutom, när det är möjligt tillhandahåller vi insiderns historiska handelsresultat. Det historiska handelsresultatet är ett vägt genomsnitt av resultatet för faktiska köptransaktioner på den öppna marknaden som insidern gjort. För mer information om hur detta beräknas, titta på detta YouTube-webinarium.
