# How to Read Market Sentiment Data to Time Your Next Investment
Market sentiment measures investor emotion and behavior, not just economic fundamentals. While growth, inflation, and interest rates move prices, fear and greed drive shorter-term swings. Learning to read sentiment indicators helps you spot opportunities others miss.
Sentiment data comes from multiple sources. The VIX, or Volatility Index, tracks fear in the S&P 500. When the VIX rises above 20, investors grow nervous. Values below 15 suggest complacency. The put-call ratio compares bearish and bullish options trades. A high ratio signals fear; a low one hints at overconfidence.

Combine sentiment with fundamentals for best results. Sentiment alone misleads. High fear paired with solid earnings growth often precedes rallies. High optimism with deteriorating fundamentals warns of pullbacks.
Track sentiment trends, not single readings. One day of negative sentiment means little. Three weeks of rising fear levels tells a real story.
