It’s the Biggest Day of the Year! (Well, Theoretically)

3,230.78

That’s the number that should be on investors minds today. Why? Simple. If the S&P 500 Index closes above that level today (it closed at 3,283,66 on Jan. 30th, so anything better than a daily decline of -52.88 SPX points will do the trick), the Stock Traders Almanac venerable “January Trifecta” will generate a bullish signal for the rest of 2020 (i.e., in theory the signal would be bullish for the stock market from the end of January 2020 through the end of December 2020).

The January Trifecta

Because STA is a paid service, and because I am a paying member, I would prefer not to explain all of the details of what comprises the January Trifecta.  Instead I will focus simply on historical results.

The Measurements

For testing purposes, we will be excluding the month of January entirely from our results since any new signal begins at the end of January and any existing buy signal expires at the end of December.

So, we will look at results in two ways:

*S&P 500 price performance from the end of January through the end of December if the January Trifecta DOES give a bullish signal

*S&P 500 price performance from the end of January through the end of December if the January Trifecta DOES NOT give a bullish signal

Figure 1 displays the price performance (growth of $1,000) for the S&P 500 Index for the months of February through December ONLY in those years when the January Trifecta was bullish.

Figure 1 – Growth of $1,000 in S&P (price only) Jan 31st through Dec 31st if STA January Trifecta IS BULLISH (1950-2019)

Figure 2 displays the price performance (growth of $1,000) for the S&P 500 Index for the months of February through December ONLY in those years when the January Trifecta was NOT bullish.

Figure 2 – Growth of $1,000 in S&P (price only) Jan 31st through Dec 31st if STA January Trifecta IS NOT BULLISH (1950-2019)

To better appreciate the implications, Figure 3 displays the two equity curves on the same chart.

Summary

Is the stock market “guaranteed” to rally between January 31, 2020 and December 31, 2020 if the S&P 500 Index closes above 3,320.78 on Jan. 31st?

No.  An 87% historical win rate is NOT a 100% historical win rate.

But history suggests that giving the bullish case the benefit of the doubt would be the proper course of action.
