Understanding the Index

The Fear & Greed Index ranges from 0 to 100:

0-24: Extreme Fear
25-49: Fear
50-74: Greed
75-100: Extreme Greed

When the index shows "Extreme Fear," it suggests investors are overly worried, which might represent a buying opportunity. Conversely, "Extreme Greed" could mean the market is due for a correction.
