Does Santa Claus Visit the Stock Market?

Does Santa Visit the Stock Market?

We know that Santa slides down chimneys all over the world on Christmas Eve—but does he visit the stock market, too?

According to the Santa Claus Rally, he does. This is the theory that there is a sustained increase in the stock market during the last week of December, right after Christmas, that lasts through the first couple days of January. The Stock Trader’s Almanac found that since 1950, the S&P 500 has gained an average of 1.4% during this period. In the past 20 years, we’ve seen this "Santa Claus Rally" every December with the exception of five.

Some people believe this increase is due to end-of-year optimism and generosity—even among investors and brokers. It's also tax planning season, and some investors may be selling off underperforming stocks to write off losses, which could trigger some upward momentum. Additionally, holiday bonuses may give individuals extra capital to invest.

Others speculate that it's because professional managers are on vacation, leaving bullish retail investors more room to sway the markets.

From Santa to January

The Santa Claus Rally may also be the precursor to the January Effect—the idea that stocks rise during the first month of the year. This trend was especially strong from 1904 to 1974, when Januarys yielded returns five times higher than other months. However, since 2000, this pattern has diminished. It's now more of a 50/50 bet, with stocks just as likely to dip as they are to rise in January.

Some say this shift occurred because investors started acting on the January Effect early, pushing gains into December instead. Additionally, tax-sheltered retirement plans like IRAs and 401(k)s have changed tax strategies and investment behavior, further muting the January Effect.

A Word on Seasonality and Bias

As we mentioned in our article about the “September Effect”, correlation doesn’t equal causation. While seasonal patterns like the Santa Claus Rally or January Effect are fun to observe, they shouldn't be the backbone of your investment strategy.

In fact, patterns like these are a good reminder to stay aware of behavioral investing biases that can skew decision-making. The key is to rely on data, not sentiment.
