Introduzione

Questa pagina fornisce un'analisi completa dello storico delle operazioni di insider trading note di William J Peters. Gli insider sono funzionari, direttori o investitori importanti di una società. In generale, è illegale per gli insider effettuare operazioni di compravendita nelle loro aziende sulla base di informazioni materiali non pubbliche. Ciò non significa che sia illegale per loro effettuare qualsiasi operazioni di trading nelle proprie aziende. Tuttavia, devono segnalare tutte le operazioni alla SEC tramite un modulo 4. Nonostante queste restrizioni, la ricerca accademica suggerisce che gli insider, in generale, tendono a sovraperformare il mercato nelle proprie società.

Redditività media delle transazioni

La redditività media delle transazioni è il rendimento medio di tutti gli acquisti effettuati sul mercato aperto dagli insider negli ultimi tre anni. Pe calcolarla, esaminiamo tutti gli acquisti non pianificati effettuati dall'insider sul mercato aperto, escludendo tutte le operazioni che sono state parte di un piano di trading 10b5-1. Calcoliamo quindi la performance media di queste operazioni nell'arco di 3, 6 e 12 mesi e facciamo la media di ciascuna di queste durate per generare un indicatore di performance finale per ogni operazione. Infine, facciamo la media di tutti gli indicatori di performance per calcolare un indicatore di performance per l'insider. Questo elenco comprende solo gli insider che hanno effettuato almeno tre operazioni negli ultimi due anni.

Se la redditività delle operazioni di questo insider è "N/D", l'insider non ha effettuato acquisti sul mercato aperto negli ultimi tre anni, oppure le operazioni effettuate sono troppo recenti per poter calcolare un indicatore di performance affidabile.

Frequenza di aggiornamento: giornaliera

Come interpretare i grafici

I grafici seguenti mostrano l'andamento dei titoli dopo ogni operazione di mercato aperto non pianificata effettuata da William J Peters. Per operazioni non pianificate si intendono operazioni non effettuate nell'ambito di un piano di trading 10b5-1. La performance dei titoli è rappresentata come variazione percentuale cumulativa del prezzo delle azioni. Ad esempio, se un'operazione di insider è stata effettuata il 1° gennaio 2019, il grafico mostrerà la variazione percentuale giornaliera del titolo fino ad oggi. Se il prezzo dell'azione passasse da 10 a 15 dollari durante questo periodo, la variazione percentuale cumulativa del prezzo dell'azione sarebbe del 50%. Una variazione di prezzo da 10 a 20 dollari sarebbe del 100%, mentre una variazione di prezzo da 10 a 5 dollari sarebbe del -50%.

In definitiva, cerchiamo di determinare la correlazione tra le operazioni dell'insider e i rendimenti in eccesso (positivi o negativi) del prezzo dell'azione, al fine di capire se l'insider sta programmando le proprie operazioni per trarre profitto da informazioni privilegiate. Immaginiamo che un insider stia facendo questo. In questa situazione, ci aspetteremmo (a) rendimenti positivi dopo gli acquisti, oppure (b) rendimenti negativi dopo le vendite. Nel caso (a), il grafico ACQUISTO mostrerebbe una serie di curve ascendenti, indicando rendimenti positivi dopo ogni operazione di acquisto. Nel caso (b), il grafico VENDITA mostrerebbe una serie di curve inclinate verso il basso, indicando rendimenti negativi dopo ogni operazione di vendita.

Tuttavia, questo non è sufficiente per trarre conclusioni. Se, ad esempio, il prezzo delle azioni della società è aumentato in maniera non ciclica per molti anni, allora ci aspetteremmo che tutti i grafici post-acquisto abbiano una pendenza rivolta verso l'alto. Allo stesso modo, ribassi non ciclici per molti anni darebbero luogo a grafici post-negoziazione rivolti verso il basso. Nessuno di questi grafici suggerisce un'attività di insider trading.

L'indicatore più forte sarebbe una situazione in cui il prezzo delle azioni fosse estremamente ciclico e vi fossero segnali positivi nel grafico ACQUISTO e curve negative nel grafico VENDITA. Questa situazione suggerirebbe che l'insider sta programmando le operazioni di trading per trarne un vantaggio finanziario.
