AI Summary
Summary
Key Signal: The Investors Intelligence (II) poll shows bullish sentiment surpassing 60% for the first time since late 2024, triggering a contrarian warning signal for potential market weakness ahead.
Historical Performance Data:

- One-year returns averaged 4.84% compared to the typical 8.59%
Most Concerning Scenario:
When bullish sentiment exceeds 60% while the SPX trades within 1% of all-time highs (10 of 22 historical cases), returns were notably weaker:
