James Chao - Insider Trading Tracker

Westlake Corporation

Introduksjon

Denne siden gir en grundig analyse av den kjente historikken for insidernes handelsaktiviteter for James Chao. Insidere er ledere, direktører eller betydelige investorer i et selskap. Det er ulovlig for insidere å gjøre handler i deres selskaper basert på spesifikke, ikke-offentlig informasjon. Dette betyr ikke at det er ulovlig for dem å gjøre noen handler i deres egne selskaper. Imidlertid må de rapportere alle handler til SEC via et skjema 4. Til tross for disse begrensningene, antyder akademisk forskning at insidere - generelt sett - har en tendens til å overgå markedet i sine egne selskaper.

Gjennomsnittlig handelslønnsomhet

Den gjennomsnittlige handelslønnsomheten er den gjennomsnittlige avkastningen av alle åpne markedskjøp gjort av insideren de siste tre årene. For å beregne dette, undersøker vi hvert eneste åpne marked, uplanlagte kjøp som er gjort av insideren, men dette inkluderer ikke alle handler som ble markert som en del av en 10b5-1 handelsplan. Vi beregner deretter gjennomsnittlig ytelse av disse handlene over 3, 6 og 12 måneder, gjennomsnittlig hver av disse varighetene for å generere en endelig ytelsesmåling for hver handel. Til slutt,

Dersom lønnsomheten for denne interne handelen er "N/A", har enten den interne personen ikke gjort noen åpen-markeds kjøp de siste tre årene, eller så er handlene for nylig til å beregne en pålitelig prestasjonsmåler.

Hvordan tolke diagrammene

De følgende diagrammene viser aksjens ytelse etter hver åpen markedstransaksjon som ikke var planlagt, utført av James Chao. Ikke-planlagte handler er handler som ikke ble gjort som en del av en 10b5-1 handelsplan. Aksjeytelsen er kartlagt som kumulativ prosentendring i aksjekursen. For eksempel, hvis en innsidehandel ble gjort 1. januar 2019, vil diagrammet vise daglig prosentendring for verdipapiret til dagens dato. Dersom aksjeprisen går fra $10 til $15 i løpet av denne tiden, vil den kumulative prosentendringen i aksjeprisen være 50%. En endring i prisen fra $10 til $20 vil være 100%, og en endring i prisen fra $10 til $5 vil være - 50%.

Til syvende og sist er målet vårt å avgjøre hvor tett insidernes handler korrelerer med overavkastninger (positiv eller negativ) i aksjekursen for å se om insidere timer sine handler for å tjene på intern informasjon. Se for deg en situasjon der en insider gjør dette. I denne situasjonen, forventer vi enten (a) positive avkastninger etter kjøp, eller (b) negative avkastninger etter salg. I tilfelle (a) KJØP-diagrammet ville vise en serie av oppadgående kurver, som indikerer positive avkastninger etter hver kjøpstransaksjon. I tilfelle (b) ville SALG-diagrammet vise en serie av nedadgående kurver, som indikerer negative avkastninger etter hver salgstransaksjon.

Imidlertid er dette alene ikke nok til å dra konklusjoner. Hvis, for eksempel, aksjeprisen for selskapet steg jevnt over mange år uten å følge en syklisk trend, ville vi forventet at alle postkjøpsdiagrammer skal ha en stigende trend. På samme måte vil ikke-sykliske nedganger over mange år resultere i nedadgående trend i post-trade diagrammer. Ingen av disse diagrammene ville antyde aktiviteter som insidertrening.

Den sterkeste indikatoren ville vært en situasjon der aksjekursen var ekstremt syklisk, og det var både positive signaler i KJØPSdiagrammet og negative plot i SALGSdiagrammet. Denne situasjonen ville vært sterkt antydende om en insider som timet handler til sin økonomiske fordel.
