Understanding the fear and greed index

Investing evokes intense emotions. Our feelings about the markets fluctuate drastically, shifting between optimism and dread. This pendulum swings between euphoria and anxiety is known as the investor sentiment cycle. Learning to recognise its patterns is vital for investment success. This is where the Fear and Greed Index comes in.

The Fear and Greed Index, also called the Market Mood Index, aims to quantify investor emotion. It assigns a numerical score representing the sentiment driving markets at any moment. The index ranges from 0 to 100. Low values signify extreme fear, while high values indicate unchecked greed. Identifying current sentiment provides insight into market psychology crucial for informed investment decisions.

What does the fear & greed index represent?

The Fear and Greed Index measures the relative levels of two opposing emotions - fear and greed - among stock market investors at a given time. It aims to quantify investor sentiment numerically on a scale from 0 to 100.

The index was created in the early 2000s by analysts to gauge the influence of psychology on investor decisions and stock prices. It is calculated daily based on a combination of technical and survey inputs.

Key elements of the fear & greed index

The Fear and Greed Index incorporates two categories of metrics in its calculation.

Price-based metrics analyse technical stock market data to assess investor sentiment. They include -

• Price momentum
• Number of stocks hitting 52-week highs vs. lows
• Proportion of stocks advancing vs. declining
• Put and call options volume
• Market volatility

How does the fear & greed index function?

The Fear and Greed Index algorithm analyses the metrics input each day to generate a score from 0 to 100 reflecting market sentiment. The calculation gives no single indicator disproportionate weight.

Scores below 20 indicate extreme fear. Readings above 80 signify extreme greed. The 40 to 60 range reflects neutral sentiment. Comparing the latest readings to past values provides context for assessing current investor psychology.

Some details on how the calculation works.

• Price-based metrics are scored based on their relationship to sentiment, then normalised to a 0 to 100 scale. For example, high volatility signals greater fear.
• Survey-based metrics directly provide sentiment readings on a 0 to 100 scale. For example, the investor survey may ask respondents to rate sentiment on a 1 to 7 scale.
• The final index reading is a weighted average of the normalised price metric scores and raw survey scores.

The index aim is not to predict markets, but rather measure the current level of fear and greed they reflect. Tracking its daily values allows investors to gauge extremes in market psychology.

Benefits of using the fear & greed index

The Fear and Greed Index provides investors two main benefits.

Identifying sentiment extremes - Readings below 20 or above 80 often indicate a divergence between investor emotion and market fundamentals. Recognising when panic or euphoria detach from fundamentals provides potential investment opportunities.

Contextualising markets - Seeing where current readings fall relative to past values offers perspective on market behavior. A reading of 45 may feel quite fearful in a bull market but neutral after a correction. Understanding relative sentiment helps investment decisions.

The index allows assessing markets objectively, beyond simply reacting to them. This helps investors avoid buying when greed pushes markets too high or panicking when temporary fear drives prices too low. Used prudently, it promotes disciplined investing anchored in data rather than emotion.

Limitations of the fear & greed index

While beneficial, the Fear and Greed Index does have some limitations to consider.

• Not a precise market timing tool - it identifies sentiment extremes but does not pinpoint reversals.
• Reflects current sentiment only; does not predict future performance.
• Some input data availability constraints exist.
• Works best alongside fundamental, technical, and macroeconomic indicators, not as a standalone tool.

The index does not indicate precisely when to buy or sell. But used with other analysis, it provides valuable input for investment decisions. Understanding both the pros and cons allows maximising its utility.

Conclusion

The Fear and Greed Index delivers an unbiased, quantified measure of investor sentiment. Monitoring its ups and downs aids long-term investment success. It should complement evaluation of fundamentals, technicals, and macro trends for a complete perspective.

While just one tool among many, understanding the cycle between fear and greed is key for investing wisely. Utilising the Fear and Greed Index moves investors closer to mastering emotional cycles and investing with conviction.
