Behavioural finance is a relatively new but rapidly evolving field that explains economic decision-making by cognitive psychology, conventional economic and financial theory. Behavioural finance searches for the influence of psychology on the behavior of financial practitioners and the subsequent effects on the financial markets. The purpose of the paper is the behavioural research aspects of financial decision-making as they help explain why and how markets might be inefficient. Hence, it becomes necessary for researchers to study the various available literatures on Behavioral Finance and its determinants that are useful to understand the better understanding of behavioural finance for the researchers and users. The paper reviews the comprehensive literature on behavioural finance and comes out with research gaps to further explore this emerging field having lots of research potential.
