Sevens Report: December Strength Usually Comes Late in the Month
History shows early December choppiness often gives way to a strong year-end rally.

Seasonal reversals like the one seen this November are far from unusual, according to Sevens Report Research. Analysis from Sevens Report shows that in more than 70% of Decembers since 1950, markets have experienced a weak or choppy first half followed by stronger gains into year-end.
December remains one of the market’s most reliable months overall. The S&P 500 has averaged a 1.4% return over the past 75 years and finished higher nearly three-quarters of the time, giving it the highest historical win rate of any month. However, Sevens notes that most of those gains typically come late.
Returns through the tenth-to-last trading day of December average just 0.1%, meaning the bulk of the month’s upside historically occurs during the final two weeks, coinciding with the Santa Claus rally. Data from the Stock Trader’s Almanac confirms a similar pattern.
Given these persistent seasonal trends, Sevens Report Research continues to favor maintaining exposure to large-cap and technology stocks into the end of the year.
