Investors cautious as US stock market sentiment becomes overheated

The recent survey conducted by the American Association of Individual Investors has raised concerns about the sentiment in the US stock market. The survey revealed a significant increase in sentiment, jumping from 28.0% to 41.7%. This surge marks the largest one-week increase since January and also represents the highest reading since the peak on July 3rd at 45.0%, which was the peak of the year. While this number is not an immediate sell signal, it is noteworthy that it has surpassed the long-term average of 37.5% for the first time in seven weeks.

One notable aspect of the survey is the stark divide in the market sentiment, with bearish sentiment currently at 42.4%, still above the long-term average of 31.0%. On the bullish side, the all-time high of 75% was observed at the peak of the dot-com bubble on January 6, 2000. More recently, the 2021 peak reached 56.9% in early April and it wasn’t until December of that year that the market reached its peak and began to decline. Another interim peak was noted in July 2024 at 52.7% bullish sentiment, which was closely followed by a 9.7% correction that was halted when the Federal Reserve indicated rate cuts.

In summary, while it may not be cause for immediate concern, it is advisable to keep a close watch on this indicator, particularly if it surpasses 50% and certainly if it exceeds 55%. This indicator has historically been correlated with market peaks and subsequent corrections, making it a valuable tool for investors to monitor market sentiment and potential risks in the US stock market.
