You've probably seen it. That colorful speedometer on CNN Business with the needle flickering between a deep, panicked red and a lush, glowing green. It looks simple. It looks like a cheat code for Wall Street. But honestly, the fear and greed index stock market tracker is a lot weirder than most people realize.
Markets aren't just numbers on a screen; they are a massive, collective nervous system. When everyone is high-fiving in the Discord chats because their tech stocks are up 40%, that's greed. When the headlines start screaming about inflation or "black swan" events and everyone hits the sell button at once, that’s fear.
The index basically tries to put a number on those feelings.
On January 16, 2026, the index sat at 62. That’s "Greed." It sounds bad, like we're all being reckless, but in a bull market, greed can be the engine that keeps things moving for months. You can’t just look at a high number and assume a crash is coming tomorrow. It doesn't work that way.

What Actually Goes Into the Fear and Greed Index?
Most people think it’s just a sentiment poll. Like someone called up a bunch of traders and asked, "Hey, how are you feeling today?"
Nope.
It’s calculated using seven distinct market signals. Each one is a different way of measuring how much "risk" people are willing to take. CNN takes these seven things, sees how far they’ve veered from their usual averages, and mashes them into a single score from 0 to 100.
The Seven Pillars of Market Emotion
- Market Momentum: This compares the S&P 500 to its 125-day moving average. If the index is way above that line, people are chasing the trend. That's greed.
- Stock Price Strength: This looks at the number of stocks hitting 52-week highs versus those hitting 52-week lows on the NYSE.
- Stock Price Breadth: It’s not just about the big names. This uses the McClellan Volume Summation Index to see if the whole market is participating in a rally or just a few giants.
- Put and Call Options: Are people buying "puts" (insurance against a drop) or "calls" (bets on a rise)? If the put/call ratio is low, traders are getting cocky.
- Junk Bond Demand: When investors are greedy, they don’t mind buying "junk" bonds with higher risk. If they start demanding safer government bonds instead, the needle moves toward fear.
- Market Volatility: This is the famous VIX. It measures how much movement people expect in the next 30 days. High VIX = high fear.
- Safe Haven Demand: This looks at the difference between stock returns and bond returns over the last 20 days.
The 2025 Rollercoaster: A Reality Check
Take a look at late 2025. In mid-October, the index tanked into the 20s. We were in "Extreme Fear" territory. The vibes were terrible. But if you actually looked at the S&P 500, it wasn't collapsing into a black hole; it was just a healthy correction after a massive AI-driven rally earlier that summer.
This is where people get it wrong.

They see "Extreme Fear" and think the world is ending. Professional contrarians—the folks who follow Warren Buffett’s advice to "be greedy when others are fearful"—see that 20 or 25 reading as a massive "Buy" signal.
Historically, the index has bottomed out at some pretty dark times. During the 2008 financial crisis, it hit a low of 12. In March 2020, when the world realized the pandemic was real, it touched a terrifying 2.
If you bought when the index was at 2, you made a fortune.
Why You Shouldn't Trade Based on One Number
It’s a lagging indicator. Basically, it tells you how people have been acting, not necessarily what they will do in ten minutes.
You’ve gotta be careful. Sometimes the market stays greedy for a long, long time. In 2017, the index stayed in the "Greed" or "Extreme Greed" zone for what felt like forever during the FAANG rally. If you sold the moment it hit 75, you missed out on months of gains.
The index is a thermometer, not a crystal ball. It tells you the market has a fever, but it doesn't tell you when the fever will break.

This happens when the stock prices are going up, but the fear and greed index stock market reading starts falling. It means the "rally" is losing its soul. Maybe fewer stocks are participating, or maybe professional traders are starting to buy put options as insurance even while the price looks high.
We saw this in late December 2025. While some sectors were still hitting highs, the junk bond demand started to dry up. The "smart money" was getting nervous even though the "dumb money" was still buying the dip.
Actionable Steps for Using the Index
Don't just stare at the needle. Use it as a filter for your own emotions.
- Check the "Neutral" Zone: When the index is between 45 and 55, it’s often a "wait and see" period. Don't force trades when the market doesn't have a clear emotional direction.
- Look at the Sub-Indicators: CNN actually lets you see which of the seven factors is driving the score. If the VIX is high (fear) but "Stock Price Strength" is also high (greed), you have a fragmented market. This usually means high-stakes volatility is coming.
- Set Your Own Thresholds: Most successful contrarians don't move at 30 or 70. They wait for the extremes—below 15 or above 85. That’s where the "rubber band" of market emotion is most likely to snap back.
- Combine with Fundamentals: Never buy a stock just because the index is at 10. Make sure the company actually has a balance sheet that can survive the "Extreme Fear" period.
The fear and greed index is a tool for perspective. It reminds us that behind every candle on a chart is a human being who is either feeling incredibly brave or absolutely terrified. Your job is to stay somewhere in the middle.
Review the current sub-components of the index today to see which specific factor—momentum, volatility, or bond demand—is currently pulling the needle the hardest. This will tell you whether the current mood is driven by genuine economic data or just a short-term panic in the options market.
