What Is the Fear & Greed Index?
CNN Business's Fear & Greed Index measures the emotional state of US equity market participants on a scale of 0 to 100. A reading near 0 reflects Extreme Fear; a reading near 100 reflects Extreme Greed. It is updated daily and is one of the most widely referenced sentiment gauges in retail investing.
The index does not track a single data point. It aggregates 7 market indicators, each normalized to a 0–100 scale based on their deviation from a 52-week average, and averages them with equal weight.
Reading the Scale
Extreme Fear
Panic — historically a buying opportunity zone
Fear
Anxiety dominant — potential oversold conditions
Neutral
Balanced sentiment
Greed
Optimism — watch for overheating
Extreme Greed
Bubble risk — consider raising cash buffer
The 7 Component Indicators
Each of these indicators is scaled 0–100 relative to its 52-week range, then averaged equally into the final score.
Stock Price Momentum
How far the S&P 500 is above or below its 125-day moving average. Trading above = greed signal; below = fear.
Stock Price Strength
Ratio of NYSE 52-week highs to 52-week lows. More new highs = greed; more new lows = fear.
Stock Price Breadth
Volume in advancing stocks vs. declining stocks (McClellan Volume Summation Index). Broad participation = greed.
Put/Call Options Ratio
Heavy put buying vs. call buying signals fear; more calls than puts signals greed.
Junk Bond Demand
The yield spread between junk bonds and investment-grade bonds. Narrow spread = risk appetite (greed); wide spread = risk aversion (fear).
Market Volatility (VIX)
The CBOE Volatility Index. High VIX = fear; low VIX = complacency / greed.
Safe Haven Demand
Capital flows into Treasuries relative to equities. Heavy bond buying signals fear; equity preference signals greed.
How to Use It in Practice
The Fear & Greed Index is not a short-term timing tool. An Extreme Fear reading does not guarantee a next-day bounce — markets can keep falling for weeks. The index's real value is as a sentiment backdrop, not a buy/sell trigger.
Think of it as a context overlay: when the index recovers from below 30, the probability of being near a bottom is historically elevated. When it has been above 80 for an extended period, a correction is statistically more likely — though “more likely” can still mean months away.
Strategy Guide by Zone
0–24 (Extreme Fear)
Consider staged buying — a potential chance to buy quality assets cheaply. Split into 2–4 tranches rather than investing everything at once.
25–44 (Fear)
Build watchlists and prepare — but don't rush. The market can fall further.
45–55 (Neutral)
Portfolio review — no major directional shift; maintain existing plan.
56–74 (Greed)
Pause new entries — markets have already run. Consider trimming some gains.
75–100 (Extreme Greed)
Raise cash buffer, reduce leverage. This is where Buffett historically accumulated cash.
Historical Episodes of Extreme Fear
Looking back at periods when the index dropped below 10, each turned out to be a significant buying opportunity in hindsight. The challenge — as always — is acting when the fear feels most justified.
March 2020 (COVID shock)
Score 2–5S&P 500 fell −34%, then rallied +75% within 12 months
October 2022 (rate hike shock)
Score 5–10S&P 500 gained +30%+ over the following 14 months
December 2018 (trade war fears)
Score 8–12S&P 500 gained +30%+ over the following 12 months
These outcomes are only clear in hindsight. At the time, each felt like the market might fall further. That is why staged buying — rather than all-in or all-out — is the practical approach.
4 Common Misunderstandings
Low score = market bounces tomorrow
Extreme Fear marks a candidate bottom, not a guaranteed next-day reversal. Fear can deepen further.
High score = sell everything immediately
Greed can persist for months. Check position sizing and leverage first; wholesale selling is rarely the right answer.
This index replaces other analysis
It does not substitute for earnings data, interest rates, currency, or individual fundamentals. It is a supplementary thermometer.
It applies equally to KOSPI
The CNN index is built on US equity, options, and bond market data. It does not map 1:1 to Korean market sentiment.
