BEHAVIORAL FINANCE
Back to GlossaryDefinition
The study of how cognitive biases influence investor behavior and markets.
Summary
Behavioral Finance is a field that combines psychology and economics to understand why people make irrational financial decisions. Unlike traditional finance theory, which assumes investors always make logical choices, behavioral finance recognizes that emotions, mental shortcuts (heuristics), and cognitive errors significantly impact how people invest, spend, and manage money. It explains phenomena like market bubbles, panic selling, and why investors often buy high and sell low despite knowing better.
Usage Context
Understanding behavioral finance is crucial when studying market anomalies, investment psychology, risk management, and explaining why markets sometimes deviate from theoretical predictions. It's particularly important in portfolio management and financial planning courses.
Common Confusions
- Thinking behavioral finance only applies to individual investors (it also explains institutional and market-wide phenomena)
- Believing that knowing about biases automatically prevents them
- Confusing behavioral finance with technical analysis or market timing strategies
- Assuming all market movements are due to behavioral factors rather than fundamental changes
