Fear and Greed Index: a practical guide for stock sentiment
How the Fear and Greed Index works, what its seven inputs measure, and how to pair it with a per-stock hot or cold sentiment read.
What the index actually measures
The Fear and Greed Index is a 0–100 sentiment gauge for the market as a whole. Zero is extreme fear, 100 is extreme greed, and 50 is neutral. It does not forecast earnings or value a company — it summarises how investors are behaving right now, using seven market-based inputs. That makes it a mood reading, not a valuation.
- 0–24 — extreme fear: sellers dominate, drawdowns are broad.
- 25–44 — fear: risk appetite is shrinking.
- 45–55 — neutral: no strong crowd bias.
- 56–75 — greed: buyers are chasing strength.
- 76–100 — extreme greed: crowded positioning, thinner margin for error.
The seven inputs
Market momentum
The S&P 500 versus its 125-day moving average. Well above it reads as greed; below it reads as fear.
Stock price strength
How many NYSE stocks are hitting 52-week highs versus lows. Broad new highs signal greed.
Stock price breadth
Trading volume in rising shares versus falling shares. Thin participation in rallies signals fear.
Put and call options
The put/call ratio. Heavy put buying is a classic fear reading.
Market volatility
The VIX against its 50-day average. Spiking volatility is fear.
Safe haven demand
Stock returns versus Treasury returns over 20 days. Money fleeing into bonds is fear.
Junk bond demand
The yield spread between junk and investment-grade bonds. Narrow spreads mean risk appetite, i.e. greed.
How to use it without overreading it
The index is contrarian by nature: extreme fear has historically coincided with better forward entry points, and extreme greed with crowded, fragile positioning. But it is a slow, market-wide signal. It tells you nothing about whether one particular company is being talked up or torn apart this week, and it can sit at "greed" for months while individual names collapse.
Treat it as the weather, not the forecast for your street. Use it to size risk and to sanity-check your own bias, then do the per-stock work separately.
Pairing it with a per-stock hot or cold read
Hot or Cold works one level down from the index. Instead of aggregating market internals, it reads the gossip around a single ticker first — recent headlines and chatter — then checks the financial picture, peer temperature and analyst price targets, and returns a hot, neutral or cold verdict.
The two together are more useful than either alone. A hot stock during extreme greed is a crowded trade worth stress-testing. A hot stock during extreme fear is genuine relative strength. A cold stock during extreme greed is a real warning sign that the story has broken down while everything else rallies.
