Gender Differences in Behavioral Bias and Influencing Investment Decisions

This study explores the impact of behavioral biases in gender differences on investment decisions through a literature review and case study. The traditional theoretical assumption in finance is that investors are rational. They are able to make optimal decisions based on all available information. However, real investors are often influenced by emotions, biases, and cognitive errors that lead to irrational decisions. Therefore, researchers have introduced psychological studies into traditional finance. Psychological studies have shown that people are often influenced by cognitive biases in the decision-making process. These biases are particularly significant on investment decisions, such as overconfidence bias, overreaction bias, regret avoidance bias, self-attribution bias, framing effect bias, and reference point bias. Behavioral finance assumes that individual investment decisions are imperfectly rational. It has been found that gender differences have a significant impact in behavioral biases, thereby affecting the behavioral decisions of investors. Among these common cognitive biases, risk aversion, overconfidence, anchoring effect, and loss aversion are more significant for gender differences in investment decisions.
