Intentional herding occurs when investors consciously follow the group or others in the stock market, believing they have superior information. This behavior arises from the perception of inadequate market information, leading to the replication of others' choices. The purpose of this study is to investigate the presence of herding tendencies among Swedish investors during insider trading. Focusing on intentional herding, the study utilized a quantitative method through surveys targeted at a random sample of investors in Sweden during May 2023. The results were analyzed based on variables such as education level, age, gender, income, location, occupation, and trading volume using statistical models. The study's findings reveal that age, gender, and education significantly influence investors' herding behavior, which was the dependent variable in the study. Measured on a five-point scale, respondents indicated the likelihood of buying/selling stocks based on insider activity. In summary, the study confirms the existence of herding behavior among retail investors in response to insider trading. These findings are important in distinguishing psychological effects from sound investment decisions and understanding market reactions and the demographic aspects among market participants
