AAII Sentiment Survey | Vibepedia

The American Association of Individual Investors (AAII) Sentiment Survey is a weekly gauge of how individual investors feel about the stock market's direction over the next six months. It tracks three key metrics: optimism (bullishness), pessimism (bearishness), and neutrality. When optimism surges, it signals a growing confidence among retail investors, often interpreted as a contrarian indicator by some market analysts. Historically, extreme levels of bullishness can precede market pullbacks, while extreme pessimism might signal buying opportunities. The survey offers insights into the collective 'vibe' of the individual investor base and its correlation with market movements.
