Many investors seem to be pessimistic about the direction of the market. If history is any indicator though, that’s a bad time to get out of stocks.
The American Association of Individual Investors polls its 125,000-plus members weekly on their expectations for the stock market over the next six months. The proportion expecting the market to fall is used to form a “bearish” sentiment indicator. As of February 13, the trailing eight-week average bearish percentage was about 37.7%—above the historical average of 31.0% since September 1987 and the highest since November 16, 2023.
Investors should be careful how much trust they put into these glass-half-empty views. Bearish response levels above the historical mean were followed by an average six-month US market return of 6.2%. That’s close to the average return of 5.9% following below-average bearish levels. Overall, there’s little discernable relation between the sentiment indicator and subsequent returns.
Past performance is not a guarantee of future results. Actual returns may be lower.
