Fear and Greed Index

On March 16, 2020, CNN's Fear and Greed Index hit 2 out of 100 — extreme fear. The world was shutting down, and investors were in full panic mode. Exactly one year later, the S&P 500 was up over 75% from that low. In November 2021, the same index hit 85 — extreme greed. Crypto was booming, meme stocks were flying, and everyone felt invincible. Over the next 12 months, the S&P dropped 25% and the Nasdaq fell 35%. The index didn't predict the future — it measured the present emotion of the market. And that emotion, at extremes, is almost always wrong.

How the Fear and Greed Index Works

CNN's Fear and Greed Index combines seven market indicators into a single score from 0 (maximum fear) to 100 (maximum greed). The seven components are: stock price momentum (S&P 500 vs its 125-day moving average), stock price strength (new highs vs new lows on the NYSE), stock price breadth (trading volume in advancing vs declining stocks), put/call ratio (options market sentiment), market volatility (the VIX vs its 50-day moving average), safe haven demand (stocks vs bonds performance), and junk bond demand (yield spread between junk bonds and investment-grade bonds).

Each component is scored independently, and the average creates the composite index. Readings below 25 indicate extreme fear. Readings above 75 indicate extreme greed. The middle range represents neutral sentiment.

The logic behind using this as a contrarian indicator is grounded in market mechanics. When fear is extreme, investors have already sold. Selling pressure is exhausted. Prices are depressed and future expected returns are high. When greed is extreme, investors have already bought. Everyone who wants in is already in. Prices are elevated and future expected returns are compressed. Extreme sentiment marks the point where the pendulum has swung too far and is about to reverse.

It's important to understand what the index is not. It's not a timing tool. Extreme fear can persist for weeks, and the market can continue falling after the index hits extreme fear. Extreme greed can persist for months while the market keeps rising. The value is directional, not precise. When fear is extreme, the odds favor buyers over the next 6-12 months. When greed is extreme, the odds favor caution.

Why It Matters for Investors

The Fear and Greed Index gives you an objective measurement of what you're feeling. When you feel desperate to sell, you can check the index and see that everyone else feels the same way — which should make you pause. When you feel euphoric about your returns, you can see that greed is running the market — which should make you cautious.

Historical backtesting shows that buying the S&P 500 when the index is below 20 and holding for one year has produced positive returns over 90% of the time, with an average gain of approximately 15%. Buying when the index is above 80 has produced significantly lower forward returns, with a much higher probability of negative outcomes over the following 6-12 months.

Warren Buffett summarized this principle decades before the index existed: "Be fearful when others are greedy, and greedy when others are fearful." The Fear and Greed Index simply puts a number on the "others" part.

Real Example

In December 2018, the Fear and Greed Index dropped to 3 — nearly the lowest possible reading. The S&P 500 had just fallen 20% in three months on fears of a trade war, rising interest rates, and a potential recession. Headlines screamed about bear markets and economic collapse. Investors pulled billions from stock funds. Those who bought at extreme fear were rewarded with a 29% gain in the S&P 500 over the next 12 months — one of the best years in market history. The market didn't rally because the fears were wrong (they were real). It rallied because the fears were already priced in. At extreme fear, the bad news is in the price. Any surprise to the upside sends stocks sharply higher.
