Sentiment Extreme Contrarian
Be greedy when others are fearful, fearful when others are greedy - systematically.
Opportunity
Social sentiment reaches extremes at market tops and bottoms. When everyone is bullish, they're already invested - no new buyers. When everyone is bearish, they've already sold - no new sellers. Extremes mean revert.
The insight: Sentiment can be measured systematically. When fear/greed index hits extremes, fade the crowd.
