Retail sentiment and mention spikes
What crowd chatter tells you, and why extremes are often a contrarian signal.
Online communities such as Reddit show what retail investors are excited or worried about. A sudden spike in mentions of a stock often follows a price move rather than predicting it.
How to use it
- Look for sustained, rising discussion, not one-day noise.
- Read the actual bull and bear theses, not just counts.
- Extreme euphoria near highs is a caution flag.
- Chatter on thin stocks can be manipulated.
Key takeaways
- Chatter is a mood gauge, not a forecast.
- Extremes tend to mark crowded trades.
- Cross-check with price, volume and fundamentals.
