Sentiment intensity

Sentiment Intensity

Sentiment intensity is a crucial concept in Technical Analysis and understanding market psychology. It goes beyond simply identifying whether market sentiment is bullish (positive) or bearish (negative); it quantifies *how strongly* participants feel about a particular asset, market, or economic outlook. This article will provide a comprehensive overview of sentiment intensity, its measurement, interpretation, and application in trading and investment strategies. We will explore various indicators, techniques, and resources for beginners to grasp this important aspect of financial markets.

What is Sentiment?

Before diving into intensity, let’s define market sentiment. It represents the overall attitude of investors towards a given security or market. This attitude is not based on fundamental analysis alone (though fundamentals play a role); it's a collective psychological state driven by factors such as fear, greed, hope, and uncertainty. Sentiment is often considered a contrarian indicator - meaning extreme sentiment levels can signal potential reversals in price trends.

Understanding sentiment is vital because markets are often driven by emotion, especially in the short to medium term. Ignoring sentiment can lead to misinterpreting price action and making poor trading decisions. As Candlestick Patterns demonstrate, emotion is visibly represented in price charts.

Sentiment vs. Sentiment Intensity

Sentiment tells us *which way* the wind is blowing. Sentiment intensity tells us *how hard* the wind is blowing.

**Sentiment:** Bullish, Bearish, or Neutral. A simple classification.
**Sentiment Intensity:** A numerical or scaled value representing the strength of the sentiment. For example: Very Bullish (+8), Moderately Bullish (+5), Slightly Bullish (+2), Neutral (0), Slightly Bearish (-2), Moderately Bearish (-5), Very Bearish (-8).

The intensity component is critical. A mildly bullish sentiment might not be enough to sustain a rally, while a strongly bullish sentiment can fuel a significant price increase. Similarly, a weak bearish sentiment might result in a minor correction, while a powerfully bearish sentiment could trigger a crash. Support and Resistance Levels are often tested more forcefully during periods of high sentiment intensity.

Measuring Sentiment Intensity

Several tools and techniques are used to measure sentiment intensity. These fall into several broad categories:

1. 1. 1. Survey-Based Indicators

These indicators directly gauge investor opinions through surveys.

AAII Investor Sentiment Survey (American Association of Individual Investors): This weekly survey asks individual investors if they think the stock market will be higher, lower, or unchanged over the next six months. The difference between bullish and bearish responses provides a sentiment reading. Extreme readings (very high or very low) are often seen as contrarian signals. [1]
Investors Intelligence Bull/Bear Ratio: This indicator tracks the recommendations of investment newsletters. It calculates the ratio of bullish to bearish recommendations. A high ratio suggests overoptimism, while a low ratio suggests pessimism. [2]
CNN Fear & Greed Index: This composite index combines seven different indicators (stock price momentum, stock price strength, stock price breadth, put and call options, junk bond demand, market volatility, and safe haven demand) to gauge market sentiment. It ranges from 0 (Extreme Fear) to 100 (Extreme Greed). [3]

1. 1. 2. Market-Based Indicators

These indicators derive sentiment from actual market activity, rather than directly asking investors.

Put/Call Ratio (PCR): This ratio compares the volume of put options (bets on a price decrease) to the volume of call options (bets on a price increase). A high PCR suggests bearish sentiment, while a low PCR suggests bullish sentiment. Analyzing the Options Trading volume is crucial here. [4]
Volatility Index (VIX): Often referred to as the “fear gauge”, the VIX measures market expectations of volatility over the next 30 days. A high VIX indicates higher fear and uncertainty, while a low VIX suggests complacency. Bollinger Bands often expand during periods of high VIX. [5]
Advance-Decline Line (A/D Line): This indicator tracks the cumulative difference between the number of advancing stocks and declining stocks. A rising A/D Line suggests bullish sentiment, while a falling A/D Line suggests bearish sentiment. It’s a measure of market breadth. [6]
New Highs/New Lows Ratio: This ratio compares the number of stocks reaching new 52-week highs to the number of stocks reaching new 52-week lows. A high ratio indicates bullish sentiment, while a low ratio indicates bearish sentiment.
Arms Index (TRIN): Measures the volume of advancing versus declining stocks, weighted by price. Values above 1 suggest bearish sentiment, while values below 1 suggest bullish sentiment. [7]

1. 1. 3. Social Media Sentiment Analysis

With the rise of social media, sentiment analysis tools are increasingly used to gauge investor opinion from platforms like Twitter, Reddit, and financial forums.

Sentiment Lexicons & Natural Language Processing (NLP): These techniques use algorithms to analyze the emotional tone of text data. Words are assigned sentiment scores (positive, negative, neutral), and the overall sentiment of a text is calculated. This is a complex field within Data Science.
Social Media APIs & Data Mining: Tools that allow access to real-time data from social media platforms, enabling the tracking of mentions, hashtags, and keywords related to specific assets or markets. Algorithmic Trading often utilizes this data.
Alternative Data Providers: Companies specializing in collecting and analyzing alternative data sources, including social media sentiment, to provide insights into market trends.

Interpreting Sentiment Intensity

Simply knowing the sentiment intensity is not enough. You need to understand what it means and how to interpret it.

**Extreme Readings as Contrarian Signals:** As mentioned earlier, extreme sentiment readings (very high or very low) often suggest that a trend is nearing its end. For example, if the CNN Fear & Greed Index reaches “Extreme Greed”, it might be time to consider taking profits or reducing exposure. Conversely, if it reaches “Extreme Fear”, it might be a good time to consider buying. This is a core principle of Contrarian Investing.
**Confirmation with Price Action:** Sentiment intensity should *always* be considered in conjunction with price action. If sentiment is strongly bullish, but the price is falling, it suggests that the bullish sentiment is weakening or being overwhelmed by other factors.
**Divergences:** Divergences between sentiment indicators and price action can be particularly significant. For example, if the VIX is falling while the stock market is rising, it suggests that investors are becoming complacent and that a correction might be imminent.
**Trend Strength:** Sentiment intensity can help confirm the strength of a trend. A strong uptrend accompanied by consistently bullish sentiment is more likely to continue than an uptrend with weakening sentiment. Trend Following strategies benefit from confirming sentiment.
**Identifying Potential Reversals:** Changes in sentiment intensity can signal potential reversals. A sudden shift from bullish to bearish sentiment, or vice versa, can indicate a change in market psychology and a potential turning point.

Applying Sentiment Intensity in Trading & Investment

Here are some ways to incorporate sentiment intensity into your trading and investment strategies:

**Confirmation of Trading Signals:** Use sentiment indicators to confirm trading signals generated by other technical or fundamental analysis methods. For example, if a technical indicator suggests a buy signal, check if sentiment is also bullish before entering the trade.
**Risk Management:** Adjust your position size based on sentiment intensity. During periods of extreme sentiment, consider reducing your exposure to limit potential losses.
**Contrarian Trading:** Act against the prevailing sentiment when it reaches extreme levels. Buy when everyone is bearish, and sell when everyone is bullish. This requires discipline and a strong conviction in your analysis. Mean Reversion strategies often capitalize on extreme sentiment.
**Identifying Market Tops and Bottoms:** Look for divergences between sentiment indicators and price action to identify potential market tops and bottoms.
**Improving Trade Timing:** Use sentiment intensity to fine-tune your entry and exit points. Enter trades when sentiment is confirming the trend, and exit when sentiment starts to weaken.
**Sector Rotation:** Sentiment analysis can help identify sectors that are becoming increasingly popular or unpopular, allowing you to rotate your portfolio accordingly. Consider Relative Strength Index (RSI) in conjunction with sentiment.
**Long-Term Investing:** While short-term trading focuses on rapid sentiment shifts, long-term investors can use sentiment as a gauge of overall market valuation. Extremely optimistic sentiment might suggest an overvalued market, while extremely pessimistic sentiment might present buying opportunities.
**News Sentiment Analysis:** Track how news articles and reports are portraying a particular asset. Positive news generally leads to bullish sentiment, while negative news leads to bearish sentiment. Fundamental Analysis relies heavily on interpreting news.
