What Is the Fear and Greed Index?
The Fear and Greed Index is a sentiment indicator designed to measure the emotions that drive financial markets. It evaluates whether market participants are acting out of fear or greed, offering insights into potential market trends. While it is not a tradable instrument itself, it serves as a valuable economic indicator for understanding market sentiment.
By analyzing current sentiment, traders can better anticipate market movements and make more informed decisions. Different versions of the Fear and Greed Index exist for various markets and financial products, reflecting the unique dynamics of each sector.
Two of the most common versions include:
- Stock Market Fear and Greed Index: This measures the overall sentiment in the U.S. stock market, illustrating how emotion drives market behavior. Launched by CNN Money (now CNN Business) in 2012, it ranges from 0 (Extreme Fear) to 100 (Extreme Greed), with a level near 50 indicating neutral sentiment.
- Crypto Fear and Greed Index: Introduced by Alternative.me, this index gauges sentiment in the cryptocurrency market using the same 0–100 scale. Currently, it focuses exclusively on Bitcoin (BTC), though there are plans to expand it to other major cryptocurrencies.
This index helps traders assess whether market valuations may be overextended based on emotional reactions rather than fundamentals. It also offers insight into herd mentality, showing how collective sentiment can fuel volatility.
How Does the Fear and Greed Index Work?
The stock market Fear and Greed Index is calculated using seven key market indicators that reflect trader behavior in U.S. equities. These indicators measure factors such as market volatility, stock price strength, and demand for safe-haven assets. Each is equally weighted and scored between 0 and 100.
The index acts like a barometer: when traders avoid risk, it points toward fear; when risk appetite increases, it points toward greed. Traders often use this information to judge whether markets are overvalued or undervalued.
The Crypto Fear and Greed Index operates on a similar 0–100 scoring system but uses a different set of indicators tailored to cryptocurrency markets, including volatility, social media sentiment, and dominance.

Stock Market Fear and Greed Index Indicators
The stock market index is based on seven indicators:
- Stock Price Momentum: Compares the S&P 500 to its 125-day moving average. Prices above the average indicate greed; below suggests fear.
- Stock Price Strength: Tracks the number of stocks hitting 52-week highs versus those hitting 52-week lows on the NYSE and Nasdaq.
- Stock Price Breadth: Analyzes the volume of advancing versus declining stocks on the NYSE.
- Put and Call Options: Measures the ratio of put options (bearish bets) to call options (bullish bets) on the CBOE.
- Market Volatility: Tracks the VIX volatility index relative to its 50-day moving average.
- Safe Haven Demand: Compares performance of stocks versus Treasury bonds.
- Junk Bond Demand: Examines the yield spread between high-yield bonds and investment-grade corporate bonds.
Each indicator is scored individually, and the average forms the final index value.
Crypto Fear and Greed Index Indicators
The cryptocurrency index uses six metrics:
- Volatility: Measures current Bitcoin volatility against 30- and 90-day averages.
- Market Momentum/Volume: Evaluates trading volume and momentum relative to historical averages.
- Social Media Sentiment: Tracks posts and engagement rates for Bitcoin-related hashtags on platforms like Twitter.
- Dominance: Assesses Bitcoin’s market share relative to the entire crypto market.
- Trends: Uses Google Trends data to monitor search query volume for terms related to Bitcoin.
- Surveys: This metric is currently paused but previously gathered weekly opinions from crypto investors.
These components are weighted and combined to produce the final index value.
Historical Data of the Fear and Greed Index
Historical analysis of the Fear and Greed Index can provide useful insights into how sentiment has preceded major market movements.
In early 2018, the index reached extreme greed levels (above 80), coinciding with a strong bull market. Shortly after, in February 2018, the S&P 500 corrected by more than 10%. The high index reading had signaled overvaluation and a potential reversal.
In March 2020, during the COVID-19 market crash, the index fell below 10, indicating extreme fear. This was followed by a strong market recovery fueled by fiscal and monetary stimulus. Traders who interpreted extreme fear as a potential buying opportunity profited from the rebound.
However, the index does not always predict market turns accurately. In late 2019, it signaled greed and possible overvaluation, yet markets continued climbing into early 2020 before the pandemic-induced crash.
It’s important to remember that past performance does not guarantee future results. The index is most effective when used alongside other tools like technical analysis.
How Can Traders Use the Fear and Greed Index?
The Fear and Greed Index can help traders avoid emotion-driven decisions. It can prevent buying at peaks of greed or selling during times of panic. Instead, traders can use extremes in sentiment to consider contrarian strategies.
Additionally, the index can support risk management. By identifying periods of high volatility and uncertainty, traders can adjust position sizes, set stop-loss levels, and manage exposure to higher-risk assets.
This tool should not be used alone. It works best as a complement to fundamental and technical analysis.
