Market sentiment is how investors feel about the market—and it can move prices! Here’s how to measure and use it in 2026.

Here’s what you need to know about market sentiment.

What Is Market Sentiment?

Market sentiment is the overall attitude of investors toward the market—bullish (optimistic, prices rise) or bearish (pessimistic, prices fall).

How to Measure Market Sentiment

1. VIX (CBOE Volatility Index): “Fear index”—measures expected volatility; high VIX = fear, low VIX = complacency.
2. Put/Call Ratio: Compares put options (betting price falls) to call options (betting price rises); high ratio = bearish, low = bullish.
3. Investor Surveys: AAII (American Association of Individual Investors) Sentiment Survey.
4. Market Breadth: Advancing vs. declining stocks (e.g., Advance/Decline Line—more advancers = bullish).
5. News/Social Media: Social sentiment (Twitter, Reddit), news headlines—use tools like Sentieo.
6. Margin Debt: High margin debt = bullish (investors borrowing to buy); falling = bearish.

How to Use Market Sentiment in 2026

• Contrarian indicator: Extreme sentiment can be a contrarian signal—if everyone is bullish, it’s time to be cautious; if everyone is bearish, it may be time to buy.
• Don’t rely on it alone: Combine with fundamental and technical analysis.
• Don’t trade just on sentiment: It’s a tool, not a strategy.

Common Sentiment Mistakes

• Following the crowd: Just because everyone is bullish doesn’t mean you should be—consider contrarian signals.
• Ignoring fundamentals: Sentiment can be wrong—always look at company and economic fundamentals too.
• Overreacting to short-term sentiment: Sentiment changes fast—stick to your long-term plan.
