The impact of disposition effect, herding and overconfidence on investment decision making moderated by financial literacy

Abstract

Behavioral finance elucidates how investors rationally commit errors in the process of making investment decisions as a result of cognitive and emotional biases, ultimately resulting in unfavorable investment choices. People are unable to avoid a variety of behavioral biases that have an impact on investors' investment decision-making processes. The human mind employs shortcuts and emotional filters to interpret information, leading to errors in the decision-making process. The objective of this study is to investigate and assess the impact of behavioral biases such as disposition effects, herding, and overconfidence on investment decision-making. Additionally, we will examine how financial literacy moderates these biases. The research employed a purposive sample strategy to select generation Z investors in Kediri City. The sample size of 400 respondents was determined using the Krejcie & Morgan table. This research employs the Partial Least Squares (PLS) Structural Equation Model (SEM) analysis method using the SmartPLS version 3 data processing application. The research findings indicate that the disposition effect and overconfidence exert a substantial impact on investment decision-making; however, herding does not exhibit a significant influence on investment choice-making. Financial knowledge enhances the impact of the disposition effect on investment decision-making in a positive way. Financial literacy has a negative moderating effect on the influence of herding and overconfidence on investment decision-making among Generation Z investors in Kediri City.
