Abstract

In Part 1 of this informal study, we examined several charts showing the relationship between price tops and price bottoms and my measure of small trader sentiment, the Daily Sentiment Index (DSI). In Part 2, we cited several examples with charts illustrating the relationship between small trader market sentiment and price peaks and troughs and several futures markets. A visual examination led me to the following preliminary conclusions:

  • Elevated levels of small trader sentiment (80% or higher) tended to precede or correlate closely with market peaks.
  • Low levels of small trader sentiment (20% or lower) tended to precede or correlate closely with market lows.
  • The observed correlations were sufficiently strong to warrant further investigation on a case-by-case basis to determine whether small trader sentiment was sufficiently reliable to be of value in trading and/or investing, which is the objective of this report.

Market

For this case study I selected S&P 500 futures. Given that the S&P 500 is one of the most actively traded futures markets and certainly one of the most widely followed markets internationally, it was an obvious choice for a more detailed examination. Indeed, other markets such as treasury bond futures, crude oil futures, or one of the precious metals have strong international participation. However, S&P futures are more reactive to geopolitical and fundamental economic concerns and would therefore appear to be an ideal candidate for closer investigation.

Methodology and Preliminary Observations

For this investigation, I examined the monthly S&P futures/sentiment chart for the period 2001 through 2024 (Figure 1). The sentiment data was slowed with a three period SMA to stabilize the occasional but often brief “erratic” small trader reaction to news events. Examination of the data suggest that the relationship between small trader sentiment and significant market tops and bottoms is reliable and indicative of predictive ability. I made the following assumptions in reaching the conclusions summarized below.

  • Sentiment readings of 80% or > = expect market decline
  • Sentiment readings of 25% or < = expect market rally
  • 80% or > points marked with vertical yellow line
  • 25% or < points marked with vertical green line
  • Green arrow up = "correct" correlation or forecast of low
  • Red arrow down = "correct" correlation or forecast of high

Preliminary Conclusions

ES-057: E-Mini S&P 500 Cont Liq. @ CME (Monthly bars)

Figure 1 contains considerable data. Please study it carefully. I reach the following conclusions, which may be subject to some degree of interpretation given that I have taken some liberties in defining "significant" price and sentiment levels. I note that this examination is still in its initial stages.

  • There were 8 significant monthly lows, every one of which was followed by a price increase. Low small trader sentiment was a leading indicator supporting the concept of small trader bearish sentiment as a valid contrary opinion indicator of bottoms
  • There were 8 significant monthly highs, 7 of which were followed by a price decrease. High small trader sentiment was a leading indicator supporting the concept of small trader bullish sentiment as a valid contrary opinion indicator of tops.

Stay tuned for more to follow.
