Pengaruh Bias Perilaku terhadap Keputusan Investasi dengan Fear of Missing Out (FOMO) sebagai Mediator di Indonesia

Abstract This study is based on the increasing number of investors in Indonesia, driven by the ease of access to digital platforms and growing awareness of financial management. In decision-making, many individuals face behavioral biases such as overconfidence, loss aversion, and herding behavior, which affect their rationality. The phenomenon of Fear of Missing Out (FOMO) also plays a role, representing the fear of missing investment opportunities that are perceived as profitable. This study aims to analyze the impact of behavioral biases on investment decisions with FOMO as a mediator in Indonesia. The data were processed using Partial Least Squares-Structural Equation Modeling (PLS-SEM) and analyzed using SmartPLS with 200 respondents selected through purposive sampling. The analysis found that investment decisions are significantly influenced by herding and overconfidence. Loss aversion and herding behavior influence FOMO. However, there was no significant effect of loss aversion on investment decisions or FOMO as a mediator. The results of this study emphasize the importance of understanding the dynamics of behavioral biases, particularly herding behavior and overconfidence, in influencing investment decisions. These findings underscore the need for education and mitigation strategies to reduce the impact of biases and improve individual investment rationality in Indonesia.Keywords: Loss Aversion, Herding Behavior, Fear of Missing Out (FOMO), Investment DecisionAbstrak Penelitian ini didasari oleh meningkatnya jumlah investor di Indonesia yang dipicu oleh kemudahan akses platform digital dan kesadaran akan pengelolaan keuangan.
