Abstract

The investment interest of the people in Magelang City has increased along with easier access to information through digital media, yet this condition has also led to speculative and less rational investment decisions. This study aims to analyze the influence of psychological biases such as herding bias, overconfidence bias, and optimism bias on the investment decisions made by the community. Based on theoretical review, this research is grounded in the Behavioral Finance and Prospect Theory approaches, which explain that investment decisions are not always rational and can be influenced by emotions and individual perceptions. Herding bias, overconfidence, and optimism bias were chosen because they are dominant biases in the financial decision-making process. This study uses a quantitative approach by distributing questionnaires to 100 respondents selected through purposive sampling, and the data were analyzed using multiple linear regression analysis. The results show that the three independent variables—herding bias, overconfidence bias, and optimism bias—have a significant and positive influence on the investment decisions of the people in Magelang City. Keyword: Herding Bias, Overconfidence Bias, Optimism Bias, Investment Decision.
