The S&P 500 winning streak ends (and why that's NOT a bad thing)

By Jay Kaeppel

BOTTOM LINE
April just ended the S&P 500 Index's five-month winning streak. So, is the party over? History has some clear suggestions on the topic. We examine the implications herein.

FORECAST / TIMEFRAME
None

Key points

  • The S&P 500 Index registered a five-month winning streak at the end of March 2024
  • That winning streak ended at the end of April 2024
  • History suggests a strong probability of more action to the upside in the months ahead

S&P 500 five-month winning streak ends

The S&P 500 Index closed higher every month from November 2023 through March 2024. A five-month winning streak tends to be bullish for stocks in the future (especially if the five-month gain is 25% or more). But with April closing with a monthly loss, the latest streak is over. On the face of it, this sounds like a bad thing. But if we take a closer look, history suggests something else.

The test

We will run the following test using monthly closing price data for the S&P 500 going back to 1920.

  • A signal occurs when the S&P 500 closes a monthly lower after registering five or more consecutive higher monthly closes
  • After a signal, we will buy and hold the S&P 500 for six months

To clarify, no signal occurs while a monthly winning streak remains active. The signal only occurs after the S&P 500 registers a down month after five or more up months.

The results

The chart below highlights each signal date since the 1920s with a red dot.

The table below displays a summary of SPX performance following these signals.

The chart below displays the hypothetical growth of $1 invested in the S&P 500 Index for six months following each new signal shown above.

The chart below displays the same information as the chart above on a logarithmic scale. Like anything in the market, it is imperfect and not indicative of a "sure thing." However, investing is a game of probabilities, and the equity curve's "lower left to upper right" nature is evident.

Lastly, the table below shows a further breakdown of winning and losing signals. Note the 84% Win Rate (again, implying a high probability of higher stock prices, but not a sure thing). Also, note that six-month moves of 10% or more skew 16-to-2 to the favorable side.

What the research tells us…

Will the S&P 500 be higher at the end of October than at the end of April? No one can say for sure, but the study above suggests a strong probability of just that possibility. Human nature leads most investors to think that after five consecutive up months, the stock market has "used up" most of its momentum. Likewise, when that streak ends, most investors intuitively consider it bad ("The run was nice, but now it's over"). While results can and will vary widely from signal to signal, the results above suggest that investors continue to give the bullish case for stocks the benefit of the doubt even after a five-month or more win streak ends.

Hypothetical Performance Disclosure: Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. for example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
