Herd Behavior Dynamics

Herd behavior occurs when individuals follow the actions of a larger group, often ignoring their own private information or rational judgment. In financial markets, this leads to rapid, often irrational, price movements in a single direction.

It is a classic manifestation of behavioral game theory where the fear of missing out overrides careful risk assessment. Once a trend is established, the momentum itself attracts more participants, creating a self-reinforcing cycle.

Understanding these dynamics is essential for identifying the peak or trough of a market cycle. It explains why markets frequently overshoot their fundamental values.
