Definition
Investor Psychology is the study of how human emotions, beliefs, biases, and decision-making processes influence financial decisions.
Markets are not moved only by:
-
Data.
-
Algorithms.
-
Fundamentals.
-
Technical patterns.
They are moved by people.
People who experience:
-
Fear.
-
Greed.
-
Hope.
-
Regret.
-
Confidence.
-
Panic.
The central idea:
A trader's greatest opponent is often not the market. It is their own decision-making under uncertainty.
Beginner Explanation

A strategy can work.
A chart can look perfect.
Then a trader loses because they:
-

-
Doubled down.
-
Ignored a stop loss.
-
Chased a move.
-
Took profits too quickly.

The problem was execution.

"What is the market doing?"
It is:
"Can I consistently make rational decisions while the market is moving against my emotions?"
