The Fear and Greed Index measures how two powerful human emotions—fear and greed—drive cryptocurrency market behavior. Ranging from 0 (extreme fear) to 100 (extreme greed), this psychological indicator helps traders identify potential market turning points.
Origins of the Fear and Greed Index
Originally developed by CNN Money for stock markets, the index evaluates whether assets trade above/below their intrinsic value due to emotional extremes. Stock market calculations consider:
- Stock price momentum and strength
- Trading volumes
- Put/call options activity
- Junk bond demand
- Market volatility
- Safe-haven asset demand
