In one sentence
The Fear & Greed index is a 0–100 composite of market indicators that summarizes whether investors are behaving fearfully (low scores) or greedily (high scores).
Markets are priced by people, and people swing between fear and greed. Sentiment indices try to measure that swing with a single number so you can see when the crowd has become extreme.
How the score is built
Fear & Greed-style indices combine several inputs — momentum versus moving averages, market breadth, put/call ratios, volatility (VIX), safe-haven demand, and junk-bond spreads — and normalize them onto a 0–100 scale. Different providers weight these differently, so treat the exact number as a mood reading, not a measurement.
Reading the scale
- 0–24 Extreme Fear — capitulation, high volatility, crowded downside protection.
- 25–44 Fear — risk-off tone; breadth usually narrow.
- 45–55 Neutral — no strong crowd tilt.
- 56–74 Greed — momentum-driven, dips are bought.
- 75–100 Extreme Greed — euphoric; historically fragile.
How investors use it
Contrarians look for extremes: extreme fear as a time to start buying quality, extreme greed as a time to tighten risk. Trend followers use it the other way — greed confirms an uptrend. Neither approach works in isolation; the index is a context layer, not a timing tool.
Not investment advice. Markets involve risk. AI outlooks and analytics can be wrong — never rely on TradingGenie as your only source when investing.
