When investor sentiment reaches extreme levels, it can be a contrary indicator for the stock market. For example, the highest bullish reading in the history of the American Association Of Individual Investors (AAII) Sentiment Survey was 75% bulls before the dot-com bubble popped in 2000. To give you a reference point, the average over the life of the AAII survey is 39% bulls. Sentiment readings can also be helpful when they reach extreme levels of skepticism, which is the topic we will explore in more detail below and tie it into the present day.

Was Sentiment Helpful In Late July 2015?

In July 2015, the eight-week moving average for percent bulls in the AAII Sentiment Survey dropped to an extremely low level, a level seen only two other times since 1995. The other two times were two of the best periods to invest in the last thirty years; early in 2003 and early in 2009.

What Happened Next?

If we used extreme and rare bearish sentiment as a contrary indicator on July 21, 2015, were we rewarded with gains in the stock market? No, the S&P 500 tanked 12% between July 21 and August 25, 2015 (see chart below).

Do Longer-Term Trends Look Like They Are About To Turn Back Up?

Sentiment, like many pieces of evidence can be helpful, but like anything else it should not be used in isolation. Even under ongoing bearish conditions, stocks regularly experience green days and countertrend rallies. However, for a lasting turn to occur that allows stocks to push to new highs, markets typically show improvement on many fronts. A logical question is:

Do we have set-ups in place now that look like a sustainable turn is imminent?
