Do Behavioral Biases Affect Investors’ Investment Decision Making? Evidence from the Pakistani Equity Market

Abstract

Using a unique sample constructed by 600 investors’ responses to a structured questionnaire, we investigate the impact of behavioral biases on the investors’ investment decision making in the Pakistani equity market, as well as the roles that market anomalies and financial literacy play in the decision making process. We first document the empirical evidence to support that the behavioral biases and market anomalies are closely associated and that these two factors significantly influence the investors’ investment decision making. The additional analyses confirm the mediating roles of certain market anomalies in the association between the investors’ behavioral biases and their investment decision making. Furthermore, empirical evidence reveals that financial literacy moderates the association between behavioral biases and market anomalies, and eventually influences the investors’ investment decision making. Overall, although the results are inconclusive for the relationships between certain variables, our results highlight the importance of financial literacy in terms of optimal investment decision making of individuals and the stability of the overall stock market.

“…Similarly, fewer studies have looked at the problem of luring potential and unsuccessful investors back into the market. On the other hand, ample number of prior studies (Abideen et al, 2023;Cruciani & Cruciani, 2017;Cavezzali et al, 2012) have predominantly focused on Western settings (i.e. developed countries), with fewer studies concentrating on developing countries (Behera et al, 2021;Naiwen et al, 2021;Nadeem et al, 2020), underscoring the growing need to investigate these concepts in such economies highlighting empirical and knowledge gap issues.…”
