Fear & Greed Index: Live Market Sentiment — and What to Do With It
CNN’s Fear & Greed Index compresses US equity market sentiment into a single number between 0 and 100. Readings below 25 signal extreme fear, above 75 extreme greed. For experienced investors it is not a timing signal but a contrarian indicator: historically, the most interesting phases were precisely when the index sat in the extreme zones.
What matters is how the reading is built — and what extremes have actually meant for subsequent returns.
How CNN calculates the index: the seven components
The index averages seven equally weighted sub-indicators, each measuring whether a market signal sits above or below its typical level:
- Market momentum: S&P 500 relative to its 125-day moving average
- Stock price strength: ratio of 52-week highs to lows on the NYSE
- Market breadth: volume in advancing vs. declining stocks (McClellan logic)
- Put/call ratio: hedging demand in the options market
- Volatility: VIX relative to its 50-day average
- Junk bond demand: spread between high-yield and investment-grade bonds
- Safe-haven demand: relative performance of stocks versus Treasuries
No single indicator is meaningful on its own — aggregation smooths outliers and makes the index more robust than any component.

Extremes as a contrarian indicator: what history shows
The logic is classic contrarian: when everyone is afraid, a lot of bad news is already priced in. In March 2020 and autumn 2008 the index sat deep in extreme fear — both phases turned out, in hindsight, to be exceptionally good entry points. Conversely, pronounced greed phases were often followed by below-average returns.
But the relationship is statistically noisy. Extreme fear can persist for weeks while prices keep falling. Anyone using the index as a precise buy or sell signal is overrating it. Its credible use is as a discipline tool: scrutinize new purchases harder in extreme greed, and keep your investment plan running through extreme fear.
Using sentiment in your own process
The index adds the most value combined with valuation and position sizing: if it shows extreme greed and your portfolio has drifted overweight tech after a rally, that is a concrete trigger for rebalancing. MoneyPeak complements the CNN reading with its own NLP-based sentiment score at the single-stock level — so you see not just market mood, but the mood around your positions.

Frequently asked questions
How often is the Fear & Greed Index updated?
CNN recalculates it continuously during US trading hours. In practice the daily close is enough — intraday swings carry little information.
Is extreme fear a reliable buy signal?
No. Extreme-fear phases were historically followed by above-average 6- to 12-month returns more often than not, but the index can stay in the extreme zone for weeks while prices keep falling. It works as a discipline aid, not a timing instrument.
How does it differ from the Crypto Fear & Greed Index?
The Crypto Fear & Greed Index is a separate indicator (e.g. by Alternative.me) for the Bitcoin market with its own methodology. Apart from the name and the 0–100 scale it has nothing in common with the CNN index.
