As an investor, have you ever felt yourself swayed by changes in market sentiments, worried about potential losses in your investments, or experienced the fear of missing out (FOMO) on market movements? These are all human weaknesses that investors must overcome. In such situations, utilizing the “Fear and Greed Index” can be highly beneficial. It can help you better control your investment emotions, find a balance between investing and psychology, and make more informed decisions.
What is the Greed Index? How are the values of the Fear & Greed Index defined?
The primitive Fear and Greed Index (also known as the “Greed Index,” “Fear Greed Panic Index,” or “Panic Index”) is developed by CNN Business, a division of Cable News Network (CNN). It utilizes various indicators such as stock prices, volatility, trading volume, and more to calculate a composite index that reflects investors’ sentiment and psychological state towards the market.
The CNN Fear and Greed Index ranges from 0 to 100, where higher values indicate a more greedy market sentiment, while lower values signify a more fearful market sentiment. When the Fear and Greed Index is below 20, it signifies an extremely fearful market condition, urging investors to be cautious. On the other hand, when the index exceeds 80, it indicates an excessively greedy market sentiment, prompting investors to exercise even greater caution.
How is the CNN Fear & Greed Index composed?
The CNN Fear & Greed Index is primarily composed of the following 7 indicators, which reflect market sentiment and trends. These seven indicators can be used to assess market risk and investor outlook on the stock market’s prospects:
| Junk Bond Demand | A smaller difference (or spread) between yields for junk bonds and safer government bonds is a sign investors are taking on more risk. |
| Stock Price Momentum／Market Momentum | It’s useful to look at stock market levels compared to where they’ve been over the past few months. The Fear & Greed Index uses slowing momentum as a signal for Fear and a growing momentum for Greed. |
| Put and Call Option | A ratio above 1 is considered bearish. The Fear & Greed Index uses a bearish options ratio as a signal for Fear. |
| Market Volitility | It tends to be lower in bull markets and higher when the bears are in control. The Fear & Greed Index uses increasing market volatility as a signal for Fear. |
| Stock Price Breadth | This measure looks at the amount, or volume, of shares on the NYSE that are rising compared to the number of shares that are falling. |
| Safe Heaven Demand | It shows the difference between Treasury bond and stock returns over the past 20 trading days. |
| Stock Price Strenth | It shows the number of stocks on the NYSE at 52-week highs compared to those at 52-week lows. |
