The Fear & Greed Index is a powerful tool for understanding market sentiment. While CNN’s version is widely used in traditional stock markets, a separate version exists for the cryptocurrency world. Both serve similar purposes—but they differ significantly in how they work and what they measure. In this blog, we’ll explore the key differences between the Crypto Fear & Greed Index and the CNN Fear & Greed Index, helping you decide which one is right for your trading strategy.
What Is the CNN Fear & Greed Index?
Developed by CNN Business, the traditional Fear & Greed Index is designed to measure sentiment in the U.S. stock market. It is based on seven components including:
- Stock price momentum (S&P 500 vs. 125-day average)
- Stock price strength (advancers vs decliners)
- Stock price breadth
- Put/Call ratios
- Junk bond demand
- Market volatility (VIX)
- Safe haven demand (stocks vs bonds)
It is updated once per day during U.S. market hours.
What Is the Crypto Fear & Greed Index?
The Crypto Fear & Greed Index, available on Alternative.me, is focused solely on cryptocurrencies, especially Bitcoin. It is calculated using a different set of inputs:
- Volatility (BTC price drops and spikes)
- Market momentum and volume
- Social media sentiment
- Bitcoin dominance
- Search trends (Google data)
This index also ranges from 0 (Extreme Fear) to 100 (Extreme Greed) and is updated once every 24 hours.

Why This Matters for Traders
1. Asset Type Matters
- Use CNN’s index if you’re trading U.S. stocks or ETFs.
- Use the Crypto index if your focus is Bitcoin or altcoins.
2. Sentiment Inputs Differ
The CNN index is heavily tied to institutional indicators like bond flows and volatility, while the crypto index leans into retail sentiment via social media and search trends.
3. Risk Behavior Varies
Crypto markets often react more emotionally, making fear signals stronger but also more volatile. The crypto index reflects this with sharper swings.
Use Both for Multi-Market Insights
If you’re trading both equities and crypto, tracking both indexes gives you a fuller view of overall market psychology. For example:
- Greed in crypto and fear in stocks may indicate sector rotation.
- Extreme fear in both can signal widespread panic—possibly a contrarian buy signal.
FAQs
Can I use CNN’s index for crypto trading?
No. It’s not designed for crypto and won’t reflect relevant sentiment.
Is the crypto index useful for Ethereum or altcoins?
Yes, but it’s primarily based on Bitcoin sentiment. Altcoins often follow BTC trends, so the index still offers value.
How often should I check the crypto index?
Once daily is sufficient, as it updates every 24 hours.
Are there real-time alternatives to these indexes?
Most sentiment indexes are delayed, but platforms like TradingView and LunarCrush offer near real-time social metrics.
Can both indexes be wrong?
Yes. No sentiment index guarantees price direction—use them as one part of a broader trading strategy.
