When I started my career in the investment industry, I used to read annual outlooks released by leading investment banks and asset managers with a delay of two to three months. It was much more exciting than reading science fiction: a fascinating flight of ideas on the part of analysts and strategists that had so little to do with the real state of affairs a couple of months later. “…man proposes, but God disposes…,” as they say.
And yet, you should read those outlooks in order to broaden your horizon of thinking beyond the obvious, while the ultimate decision should be yours.
That is why we should revisit one of the most famous stock market statistics called the “January Trifecta” (see Reference 1 below).
It is based on the Santa Claus rally, the New Year’s Post-Holiday rally, and the January Barometer. The Santa Claus rally reflects the stock market’s direction in the last five trading days of the outgoing year and the first two trading days of the new year. The New Year’s Post-Holiday rally shows the market performance in the first five trading days of the new year. On the other hand, the January Barometer represents the market return during the first month of the new year.
Historically, when all the three gauges were up, the Standard & Poor’s 500 Index performance for the remainder of the year has risen 90% of the time with an average gain of 17.5%. When any of the indicators were down, the stock market performance for the remainder of the year were also reduced. When all the three gauges were down, the Standard & Poor’s 500 Index fell three out of eight years with an average loss of 3.6%.
Furthermore, this trio of indicators proved to be very accurate in predicting the U.S. stock market performance in 2022 and 2023. In 2024, these indicators were also technically accurate by predicting a moderate positive return. However, the eventual outcome turned out to be almost as excellent as in 2023 (see Reference 2 and the picture below).
In 2025, the Santa Claus rally’s return was slightly negative: -0.53% (-0.88% in 2024); the New Year’s Post-Holiday Rally’s return was slightly positive: +0.62% (-0.13% in 2024), while the January Barometer’s return was decidedly positive: +2.70% (+1.59% in 2024). Thus, the 2025 stock market horoscope predicts that the market performance is likely to be at least as good as in 2023. Recalling that the January Trifecta underestimated the level of investor optimism last year, we may suggest that it may somewhat overestimate it this year. However, it certainly does not indicate investor pessimism.
Anyway, this year is likely to be very interesting. And astrology strongly supports this expectation. The thing is that in 2025 we will be able to observe a remarkable alignment of seven planets — Mars, Jupiter, Uranus, Venus, Neptune, Saturn, and Mercury — aka the Great Planet Parade. Astrologers claim that this celestial event facilitates dynamism, creativity, and development. The statistical U.S. stock market horoscope supports this view too.
Hopefully, these statistical predictions and astrological prophecies will ultimately materialize. Still, we should remember that Mark Twain once said, “There are three kinds of lies: lies, damned lies, and statistics”; Shakespeare once wrote, “The fault … is not in our stars, but in ourselves”; while one of the most famous economists of the 20th century John Kenneth Galbraight once insisted, “The only function of economic forecasting is to make astrology look respectable.” Good luck!
