12.4 Investor psychology

Investor psychology plays a crucial role in financial decision-making. It explores how human behavior and cognitive biases influence market reactions to financial reports and company disclosures. Understanding these psychological factors helps analysts interpret and predict investor responses to financial information.

Behavioral finance combines psychology and economics to explain irrational financial behaviors. It challenges traditional financial theories by acknowledging the impact of emotions and biases on investment choices. By recognizing common cognitive biases and emotional pitfalls, investors can strive for more balanced and rational decision-making in the face of market volatility.
