A score close to 0 indicates extreme fear, while a score near 100 suggests extreme greed.

Your investment decisions may benefit significantly by keeping an eye on market sentiment. Here’s how tide shifts can occur based on CFGI results:

- High Fear Levels: A reading below 30 typically indicates a fearful market, suggesting that prices may be low and offering good buying opportunities.
