First, there is the volatility indicator. Market volatility can be an important sentiment indicator, usually measured in terms of standard deviation or volatility. Common volatility indicators include daily or annualized stock price volatility.

Annualized volatility = standard deviation (daily return) x √252 (assuming there are 252 trading days in a year)

There's also the Sentiment Index, which is based on sentiment analysis of market news, social media comments, or other text data. Sentiment analysis evaluates market sentiment based on positive, negative, or neutral sentiment in the text.

Sentiment index = (number of positive sentiment words minus number of negative sentiment words)/total number of sentiment words

Finally, there is the Investor Sentiment Index, which is calculated based on investor behavior, such as trading behavior, speculative positions, or hedge fund positions.

AAII Investor Sentiment Index = (Number of buying investors - Number of selling investors)/Total number of investors

It is the lowest point in market sentiment and can occur during a market crash or major crisis. Investors may feel extremely worried and unable to react calmly to market volatility.

The "boiling point" is when market sentiment reaches its highest point and investors are in a state of extreme excitement and optimism. The market may be in a frenzy, with investors chasing stocks or other assets and prices rising rapidly, often accompanied by overvaluation and bubbles." At the "boiling point", the market may be at risk of correction or collapse.

How to judge market sentiment indicators

First, it is important to understand the types of mood indicators. Different types of sentiment indicators may focus on different aspects of market sentiment, such as consumer confidence, investor sentiment, manufacturing sentiment, etc. Different mood indicators have specific uses and ways of interpreting them.

Looking at trends in emotional indicators is a common way to judge. If the sentiment indicator is on an upward trend, it may indicate a positive development in market sentiment. On the contrary, if the indicator value falls, it may indicate that market sentiment is moving. You can also compare the current values of sentiment indicators with historical data to see if there are any significant changes.

Observe how changes in sentiment indicators correlate with market performance. For example, if a consumer confidence index is up but the stock market is down, this may indicate that the market is more sensitive to other factors or that the market has already reflected the confidence index.

Link sentiment indicators to other economic indicators, financial news, and events. Certain events or news may have a direct or indirect impact on market sentiment, so consider these factors. Understand the timing of the release of sentiment indicators and related events to help explain possible market reactions. For example, elections, economic policy changes, geopolitical events, etc. can have a significant impact on sentiment markets.

Be careful not to treat sentiment indicators as a single market forecasting tool. It is a market reference, but market sentiment itself is complex and volatile, affected by a variety of factors. Therefore, additional information and analysis are needed to make detailed decisions.

How to set market sentiment indicators

First, identify the market and asset class. Then choose the appropriate sentiment indicators, such as the volatility index, investor sentiment survey, news sentiment analysis, etc.

Get data about the selected sentiment indicator. Timely access to data from market data, news feeds, social media data, etc. is necessary to ensure the quality of the data.

Use appropriate tools and software for data analysis and calculations, including the use of statistical analysis software or professional sentiment analysis tools. Some sentiment indicators may require sentiment analysis algorithms to process text data.

According to the results of the analysis of sentiment indicators, develop corresponding trading strategies. Different emotional indicators may require different strategies. Consider how sentiment indicators can be used in conjunction with other market analysis tools.

Use charts and visualization tools to visualize mood indicator data to better understand and interpret mood trends. Visualization helps to quickly identify mood changes and potential opportunities.

Market sentiment is dynamic, so it is important to monitor and update sentiment indicators regularly. Adjust and improve your sentiment indicator settings and strategy conditions to adapt to the changing market.

Consider the possible existence and limitations of emotional indicators, and do not rely too heavily on emotional indicators to make unwise decisions. Set stop-loss and risk management strategies to reduce potential risks.
