This behavior tends to deviate from logic and reason, resulting in various behavioral biases influencing investor decisions. The main objective of this study is to analyze the effect of familiarity bias, loss aversion bias, and self-control bias on investment decision making. This study used purposive sampling method. A quantitative approach was used by distributing questionnaires online through Google Forms. This survey was attended by 245 individual investors in Yogyakarta but only 208 of them met the research criteria. Furthermore, the Structural Equation Model-Partial Least Square (SEM-PLS) analysis procedure is applied to test all hypotheses using the smartPLS application. The results showed that all variables, namely familiarity bias, loss aversion bias, and self-control bias, had a significant effect on investment decisions. These findings highlight the importance of behavioral factors in shaping investor decisions. This research provides a deeper understanding of the various behavioral biases that can influence investment decisions, as well as providing guidance for investors to consider these biases in order to make better decisions and reduce the risk of being impacted by irrational behavior.
