The Santa Claus Rally is Especially Pronounced in the DAX Author Dimitri Speck – Acting-Man
The Gift that Keeps on Giving
Every year a certain stock market phenomenon is said to recur, anticipated with excitement by investors: the Santa Claus rally. It is held that stock prices typically rise quite frequently and particularly strongly just before the turn of the year.

I want to show you the Santa Claus rally in the German DAX Index as an example. Price moves are often exaggerated in the German stock market, which leads to quite pronounced – and hence profitable – seasonal trends.
Recurring trends can be discerned at a glance on a seasonal chart
The chart below is not a standard chart that depicts a price trend over a specific time period. Rather, this seasonal chart shows the typical seasonal pattern of the German DAX Index. It illustrates the average returns generated by the index in the course of a year over the past 20 years. The horizontal axis shows the time of the year, the vertical axis shows the price information indexed to 100.
DAX, seasonal pattern over the past 20 years. The Santa Claus rally lies immediately ahead
The Santa Claus rally starts in mid-December!
The positive seasonal period near the end of the year is highlighted in dark blue on the chart. The Santa Claus rally in the DAX Index begins on December 13 and typically lasts until January 02 of the next year.
A Disproportionate Gain in Stock Prices
The average return achieved in the time period from December 13 to January 02 amounted to 3.66 percent. This gain was generated in just 19 calendar days.
Thus the Santa Claus rally on average generated an annualized gain of 99.62 percent!
For comparison: in the rest of the time the annualized gain of the DAX amounted to just 1.86 percent.
In short, the seasonal trend around the Christmas holidays is quite extraordinary.
Prices Rose in 90% of all Cases
This raises the question whether this is a robust result or if it is a statistical artifact attributable to a few outliers. Let us take a closer look at the individual years underlying the pattern.
The following bar chart shows how prices behaved in the time period from December 13 to January 02 in every year since 1997. Green bars indicate years generating gains, red bars indicate years in which losses occurred.
DAX, percentage return achieved between 13. Dec. and 02 Jan. in individual years since 1997. Most of the time the DAX rises at the end of the year.
As the breakdown illustrates, the green bars clearly dominate both in frequency and extent. The Santa Claus rally took place in 18 of the past 20 years, with the largest gain amounting to 16.13 percent (achieved in 1998). By contrast, there were just 2 years in which the Santa Claus rally failed to happen. The largest loss was recorded in 2000 and amounted to 4.99 percent.
In other words, individual outliers are not responsible for generating the market’s strength close to the end of the year. In fact, the pattern is quite stable from a statistical perspective. What causes the market’s strength at the end of the year though?
