Sentiment indicators are tools used to measure the overall mood of investors within financial markets, reflecting whether most investors are bullish (expecting prices to rise) or bearish (expecting prices to fall). These indicators are integral to technical analysis and are often used as contrary indicators by experienced traders.
Types of Sentiment Indicators
Market Sentiment Surveys
- American Association of Individual Investors (AAII) Sentiment Survey: Measures the percentage of individual investors who are bullish, bearish, or neutral on stock market trends.
- Investors Intelligence (II) Sentiment Survey: Compiles the sentiments of financial newsletter writers.
Volatility Index (VIX)
The VIX, often referred to as the “fear index,” measures market expectations of near-term volatility conveyed by S&P 500 stock index option prices. Higher VIX levels indicate higher expected volatility, usually associated with bearish sentiment.
Put/Call Ratio
This ratio compares the number of put options traded to the number of call options traded. A high put/call ratio indicates a bearish sentiment, while a low ratio indicates bullish sentiment.
Short Interest
The short interest reflects the total number of shares of a stock shorted but not yet covered. A high short interest can be a bearish indicator, though extreme levels might signal an impending short squeeze and potential rise in stock prices.
Historical Context and Applicability
Historically, sentiment indicators have been used to anticipate market reversals. The basic premise is contrarian investing, where sentiment extremes predict market turning points. For instance, during the tech bubble of the late 1990s, extreme bullish sentiment was a precursor to the market crash in 2000.
Special Considerations
- Contrarian Strategy: The success of sentiment indicators often depends on the contrarian strategy, assuming that the majority is wrong at key market turning points.
- Market Conditions: The effectiveness of sentiment indicators can vary greatly with different market conditions (e.g., a bullish sentiment in a strongly trending bull market might not signal an immediate market drop).
Examples
- AAII Sentiment Survey: An AAII survey showing 60% bullish sentiment might indicate an overbought market and potential for reversal.
- VIX Index: A spike in the VIX to levels above 30 often corresponds to heightened fear and potential market correction.
Related Terms
- Technical Analysis: Technical analysis involves studying statistical trends from trading activity, like price movement and volume, to forecast future price changes.
- Contrarian Investing: A strategy that goes against prevailing market trends by buying assets that are performing poorly and then selling when they perform well.
- Market Psychology: The overall sentiment-or mood-of market participants which can drive market movements and impact analysis such as sentiment indicators.

Summary
Sentiment indicators are valuable tools for gauging the mood of investors. By measuring levels of optimism or pessimism, these indicators can help predict potential market reversals, offering traders a contrarian perspective to accompanying trends. Whether through market surveys, the VIX, or the put/call ratio, understanding sentiment provides crucial insights for informed investing.
