The Fear and Greed Index (FGI) is a powerful tool that captures the emotional pulse of financial markets. By measuring investor sentiment, it helps traders identify potential turning points in market trends. Originally developed by CNN Money for the stock market, the index has since been adapted for cryptocurrencies and other asset classes. This guide explores how the Fear and Greed Index works, how it’s calculated, and how traders can use it effectively—without falling into common emotional traps.
Understanding the Fear and Greed Index
Fear and greed are two dominant emotions driving financial markets. When fear dominates, investors rush to sell, often pushing prices below their intrinsic value. When greed takes over, buyers flock in, inflating prices beyond fundamentals. The Fear and Greed Index quantifies these emotions on a scale from 0 to 100, where:
- 0–24: Extreme fear
- 25–49: Fear
- 50: Neutral
- 51–74: Greed
- 75–100: Extreme greed
A reading below 50 suggests bearish sentiment, while above 50 indicates bullish momentum. The index operates on a contrarian principle: when others are fearful, it may be time to buy; when others are greedy, it may be time to sell.

This psychological indicator doesn’t predict exact price movements but offers valuable context. For example, extreme fear may signal oversold conditions and a potential rebound, while extreme greed could precede a market correction.
How the Fear and Greed Index Is Calculated
CNN Money calculates the traditional stock market Fear and Greed Index using seven equally weighted indicators, each scored from 0 to 100 and averaged into a composite value.
1. Stock Price Strength
This measures the number of NYSE-listed stocks hitting 52-week highs versus lows. A high number of new highs suggests strong buying pressure (greed), while more lows indicate selling panic (fear).
2. Market Breadth
This tracks the total volume of advancing versus declining stocks on the NYSE. Widespread participation in gains signals confidence, while broad declines reflect fear-driven selling.
3. Market Momentum
Compares the S&P 500’s current level to its 125-day moving average. Outperformance indicates bullish momentum (greed), while underperformance hints at weakening sentiment.
4. Safe-Haven Demand
Analyzes investor shifts between equities and safe assets like U.S. Treasury bonds. Increased bond purchases during stock sell-offs reflect risk aversion and fear.
5. Put and Call Options Ratio
Measures the balance between put options (bearish bets) and call options (bullish bets). A high put/call ratio signals fear, while a low ratio reflects greed.
6. Junk Bond Demand
Assesses the yield spread between investment-grade bonds and high-yield (“junk”) bonds. A narrowing spread means investors are chasing riskier assets—indicating greed.
7. Market Volatility (VIX)
Uses the CBOE Volatility Index (VIX), often called the “fear gauge.” A rising VIX (above historical averages) indicates fear; a low VIX reflects complacency and greed.
Each component feeds into the final index, offering a holistic view of market psychology.
The Crypto Fear and Greed Index
With the rise of digital assets, Alternate.me introduced the Crypto Fear and Greed Index, tailored to the volatile cryptocurrency market. Updated every eight hours, it reflects the heightened emotional swings common in crypto trading.
The index combines six key factors:
- Market Volume & Momentum (25%) – High trading volume during price surges often signals FOMO (fear of missing out).
- Volatility (25%) – Measures price swings over 30 and 90 days; higher volatility increases fear.
- Social Media (15%) – Tracks sentiment from Twitter, Reddit, and hashtag activity.
- Surveys (15%) – Aggregates responses from investor sentiment polls.
- Google Trends (10%) – Monitors search interest in terms like “Bitcoin crash” or “buy Ethereum.”
- Bitcoin Dominance (10%) – Rising BTC dominance may indicate risk-off behavior.
Due to the speculative nature of crypto markets—where fundamentals are harder to assess—investor psychology plays an even larger role than in traditional markets.

Best Practices: Do’s and Don’ts of Using the Index
While insightful, the Fear and Greed Index should not be used in isolation. Here’s how to apply it wisely.
✅ Do’s
- Use it as a contrarian signal – Consider buying during extreme fear and taking profits during extreme greed.
- Combine with technical analysis – Pair index readings with support/resistance levels or moving averages for stronger entries.
- Monitor long-term trends – A single day’s reading matters less than sustained shifts in sentiment.
- Stay disciplined – Let data guide decisions, not emotion.
❌ Don’ts
- Don’t trade solely on sentiment – Always consider macroeconomic data, earnings reports, and on-chain metrics (for crypto).
- Avoid timing the absolute bottom or top – Markets can remain irrational longer than expected.
- Don’t ignore fundamentals – Even in emotional markets, valuation matters over time.
- Don’t panic during extreme readings – Extreme fear can persist during prolonged bear markets.
