What Is It?
Market psychology studies how fear, greed, herd behavior, and emotion influence financial markets.
Origin
The study of crowd behavior dates back centuries, with works such as Extraordinary Popular Delusions and the Madness of Crowds. Modern behavioral finance expanded the field by showing how investors act irrationally.
Why It Matters
Markets are often driven by emotion in the short term. Understanding psychology helps investors avoid panic selling, FOMO buying, and emotional overtrading.

Sentiment surveys, put/call ratios, social media tone, news sentiment, fund flows, volatility indexes, and retail trading activity.
