Insynshandel - Vad är den kortsiktiga marknadsreaktionen? : En kvantitativ studie gällande insynspersoners möjlighet till att generera abnormal avkastning på First North Growth Market

Sammanfattning: Insider trading has long been a controversial phenomenon in the financial world. Several studies have been conducted in the area where the studies have shown ambiguous results. In 2016, Finansipektionen amended the Insider Trading Act, namely that insiders need to report an insider transction within three days. Insiders ability to generate abnormal returns is considered to be in conflict with market efficiency.  This study examines insiders ability to generate abnormal returns on the First North Growth Market during the year 2020, where the sample consists of 47 observations. An eventstudy has been used to investigate the market reaction from the publication of insider trading. Multiple regression analysis has been applied to examine whether there is any difference in the abnormal return based on the position of the insider, the transactionsize of the insider tradingsize and the gender. The hypothesis tests have been answered with the help of a one-sided t-test and multiple regression analysis. A quantitative method and deductive approach have been used in the study where the researcher derived hypotheses based on previous research as well as theories such as the effective markethypothesis, the random-walk theory, the signalinghypothesis, behaviorbased financing and herdbehavior. This study shows that insiders generate abnormal returns during a short-term event window, but that there is no significant difference in the abnormal returns based on the insider’s position, transactionsize and gender.
