The S&P 500 has closed at new record highs in October after slipping in September, leaving many to speculate about what the S&P 500 will do next. At ITR Economics, we do not forecast the stock market, but we do like to study it. Our Trends Report™ subscribers have been hearing for the past few months that a correction in the S&P 500 is coming. To be clear, we are saying a correction, not a bear market, given that we are not forecasting a recession in the macroeconomy.

We have a collection of leading indicators, as well as our forecasts for the macroeconomy, that suggest we will see the S&P 500 tip over into Phase C, Slowing Growth, in the coming months – giving further credence to an impending correction. One such indicator we’ve been watching closely is US Domestic Corporate Profits With Capital Consumption Adjustments. Profits are at a record high and have been supporting people’s decisions to invest in the stock market. The Profits 3/12 rate-of-change has historically led the S&P 500, but during the past five years the relationship between Profits and the S&P 500 has become tighter. Our analysis shows that the Profits 3/12 is likely at its zenith and is suggesting the S&P 500 is on the verge of Phase C, Slowing Growth.

Looking deeper within the S&P 500, there are clear signs that upward momentum is fading. At ITR Economics we utilize our Checking Points™ system, and one such checking point is watching for a change in the 3/12 rate-of-change. The S&P 500 3/12 rate-of-change has been in a general declining trend for the past four months. Furthermore, the degree of decline in the 3/12 rate-of-change is quite compelling. Here’s why:

  • There are 36 similar cases in the past 120 years; all but one of those cases led to a 12/12 peak in the S&P 500.
  • On average, the subsequent 12/12 peak occurred five months after the 3/12 peak but could occur up to eight months after the 3/12 peak.
  • The S&P 500 3/12 peaked in May 2021, which suggests the 12/12 is likely to peak between October 2021 and January 2022.

Watch closely for the correction, as it will present a buying opportunity. The correction is not expected to be long – three to five months is the modern norm, so your window will be brief.
