What Is the Fear and Greed Index?

The Fear and Greed Index is a market sentiment indicator originally created by CNN Business. It measures how fearful or greedy investors are on a scale from 0 to 100:

0–24: Extreme Fear — investors are selling, markets are oversold
25–44: Fear — caution is dominant, prices may be undervalued
45–55: Neutral — no strong sentiment either way
56–74: Greed — optimism is growing, prices may be overvalued
75–100: Extreme Greed — euphoria, markets likely overbought

The index is a contrarian indicator. When everyone is fearful, it often signals a buying opportunity. When everyone is greedy, a correction may be ahead.

What Drives the Fear and Greed Index?

The CNN Fear and Greed Index combines seven market signals, each weighted equally:

1. Stock Price Momentum

Compares the S&P 500 to its 125-day moving average. When the index is well above its moving average, that signals greed.

2. Stock Price Strength

Measures the number of stocks hitting 52-week highs vs. 52-week lows on the NYSE. More new highs = more greed.

3. Stock Price Breadth

Uses the McClellan Volume Summation Index to compare advancing vs. declining volume. Wide participation in a rally indicates greed.

4. Put and Call Options

The put/call ratio measures how many protective puts are being bought vs. bullish calls. More puts = more fear.

5. Junk Bond Demand

The spread between yields on investment-grade and junk bonds. Narrow spreads mean investors are risk-seeking (greed). Wide spreads mean risk-aversion (fear).

6. Market Volatility (VIX)

The CBOE Volatility Index, known as the "fear gauge." A VIX above 20 signals fear; below 15 signals complacency.

7. Safe Haven Demand

Compares the return of stocks vs. Treasury bonds over the past 20 trading days. When bonds outperform stocks, it signals fear.

How to Read the Fear and Greed Index

The index updates daily and gives you a single-number summary of market sentiment. Here's how professional traders use it:

As a Contrarian Signal

Warren Buffett famously said: "Be fearful when others are greedy, and greedy when others are fearful." The Fear and Greed Index quantifies exactly this.

Extreme Fear (0–24): Historically, buying when the index is in extreme fear has produced above-average forward returns. Markets tend to recover from panic.
Extreme Greed (75–100): Markets at extreme greed often correct within weeks. This is a good time to take profits, tighten stop losses, or reduce position sizes.

As a Confirmation Tool

Don't trade the Fear and Greed Index alone. Use it alongside technical and fundamental analysis:

A bullish technical breakout during extreme fear? That's a stronger signal than a breakout during extreme greed.
A bearish signal while the index shows extreme greed? More likely to play out correctly.

As a Risk Management Filter

When the index is at extremes, adjust your trading behavior:

High greed: Reduce position sizes, set tighter stop losses, avoid chasing
High fear: Look for oversold setups, increase position sizes slightly, use wider stops to avoid shakeouts

Fear and Greed Index vs. VIX: What's the Difference?

The VIX (Volatility Index) is one of seven components in the Fear and Greed Index. While the VIX measures only implied volatility from S&P 500 options, the Fear and Greed Index gives a broader picture by combining multiple sentiment signals.

Feature	Fear and Greed Index	VIX
Components	7 market signals	S&P 500 options only
Range	0–100	Open-ended (typically 10–80)
Best for	Broad sentiment	Volatility expectations
Update frequency	Daily	Real-time
Contrarian use	Buy at extreme fear	Buy when VIX spikes

Both are useful, but the Fear and Greed Index is more beginner-friendly because it gives a simple 0–100 score with clear labels.

Historical Examples

March 2020 (COVID Crash)

The Fear and Greed Index dropped to 2 — near-maximum fear. The S&P 500 was down 34% from its high. Over the next 12 months, the market rallied over 75%.

January 2021 (Meme Stock Mania)

The index hit 82 during the GameStop/AMC rally. Markets pulled back sharply in February.

October 2022 (Bear Market Bottom)

The index hit 14 as inflation fears peaked. The S&P 500 bottomed that month and rallied 25%+ over the following year.

How Tradewink Uses the Fear and Greed Index

Tradewink integrates market sentiment into its AI trading pipeline in several ways:

Regime detection: The AI identifies whether the market is in a fear or greed regime and adjusts strategy selection accordingly. In extreme fear, it favors mean-reversion setups. In extreme greed, it tightens exits and reduces position sizes.
Conviction scoring: When the AI evaluates a trade candidate, market sentiment is one factor in its conviction score. A bullish setup in a fearful market gets a higher conviction than the same setup in a greedy market.
Risk management: Position sizing automatically adapts to the sentiment regime. Higher fear = wider stops but smaller positions. Higher greed = tighter stops.
Monk mode: During extreme readings, Tradewink's "monk mode" filter can pause aggressive trading strategies to avoid getting caught in euphoria-driven reversals or panic-driven capitulation.
