Price behavior in financial markets is driven by collective sentiment shifts. Tools like the Fear & Greed Index quantify these psychological fluctuations using behavioral data—trading volume, volatility, search trends, and capital flows—rather than price analysis alone.
Understanding the Fear & Greed Index
The Fear and Greed Index measures market psychology on a scale from 0 to 100 by analyzing:
- Price volatility
- Trading volume momentum
- Online search trends
- Social media sentiment
- Survey data
- Bitcoin dominance
Interpreting Index Values
| Value Range | Market Sentiment | Behavioral Indicator |
