Understanding market sentiment is essential for successful trading and investing. Among the many tools available, the Fear & Greed Index stands out for its simplicity and popularity. But how does it compare to traditional sentiment indicators like the VIX, Put/Call Ratio, or AAII Sentiment Survey? In this post, we’ll explore the differences, benefits, and use cases of each to help you choose the right tools for your strategy.
What Is the Fear & Greed Index?
Developed by CNN Business, the Fear & Greed Index is a composite sentiment tool that scores the market on a scale from 0 (Extreme Fear) to 100 (Extreme Greed). It is calculated using seven components:
- Stock price momentum (S&P 500 vs. 125-day average)
- Stock price strength
- Stock price breadth
- Put/Call ratio
- Market volatility (VIX)
- Junk bond demand
- Safe haven demand
This all-in-one gauge offers a quick snapshot of investor emotion and is updated once per trading day.
Key Traditional Sentiment Indicators
1. VIX (Volatility Index)
Known as the “fear gauge,” the VIX measures expected market volatility based on S&P 500 options.
- High VIX = High fear
- Low VIX = Calm or complacency
2. Put/Call Ratio
Tracks the ratio of bearish (put) to bullish (call) options activity.
- High ratio = More puts = Bearish sentiment
- Low ratio = More calls = Bullish sentiment
3. AAII Sentiment Survey
A weekly survey that asks individual investors whether they are bullish, bearish, or neutral.
- High bearish % = Fear
- High bullish % = Optimism
4. CNN Business News Coverage
Used as a soft indicator—overly bullish or fearful headlines often indicate emotional extremes.
5. Investor Intelligence Advisors Sentiment
Gathers opinions of newsletter writers—good for gauging long-term sentiment.

How often should I check these indicators?
Sentiment indicators like the Fear & Greed Index or AAII survey should be checked daily or weekly depending on your trading style.
