Behavioral finance is a field of study that explores the impact of psychological and emotional factors on the decision-making processes of investors and financial professionals.

By integrating insights from psychology and neuroscience with economics, behavioral finance seeks to explain market anomalies and patterns that cannot be fully accounted for by classical financial theories. It provides a more nuanced understanding of why investors often deviate from perfectly rational behavior, leading to phenomena such as market bubbles, crashes, and persistent mispricings.

The core idea is that an understanding of these psychological influences can lead to more accurate predictions of market movements and can help investors make more informed decisions by recognizing and mitigating their own cognitive biases.
