What is the Fear & Greed Index?
The stock-market Fear & Greed Index distills the emotional state of investors in the US market into a single number between 0 and 100. A low score shows that fear dominates — investors sell defensively and seek safety. A high score shows greed — strong risk appetite and confidence. The core idea is that prices are driven not only by fundamentals but also by collective psychology, and this index turns that psychology into a value you can easily track day to day.
