The January effect, a long-held belief that stocks tend to rise more in January than in any other month, has been a topic of debate among investors for decades. While historical data suggests a potential correlation, the question remains: is the January effect still relevant in today’s market?
Understanding the January Effect
The January effect was first observed by investment banker Sidney Wachtel in 1942. He noticed that small-cap stocks outperformed large-cap stocks in the first half of January, based on data from 1925. Subsequent studies confirmed this trend, with some showing January returns exceeding the average monthly return by five times
Several theories have been proposed to explain the January effect:
- Tax-loss harvesting: Investors may sell losing stocks in December to offset capital gains and repurchase them in January, driving prices higher.
- Year-end bonuses: Bonuses received in December may be invested in the market, leading to increased demand and higher prices.
- Investor psychology: The fresh start of a new year may encourage investors to be more optimistic and invest more aggressively.
The Diminishing January Effect
While the January effect was once considered a reliable market anomaly, its strength has diminished over time Studies suggest that the effect is less pronounced than it used to be, particularly for small-cap stocks.
Several factors may have contributed to this decline:
- Increased tax-sheltered accounts: The rise of IRAs and 401(k)s has reduced the need for tax-loss harvesting.
- Greater market awareness: Investors are more aware of the January effect and may adjust their strategies accordingly.
- Changes in market dynamics: The dominance of large-cap technology stocks and the overall market volatility may have obscured the January effect.
The January Effect in 2024
Given the diminishing January effect and the strong market rally in the last two months of 2023, many investors are skeptical of a significant January effect in 2024. However, it’s important to note that the January effect is not a guaranteed phenomenon, and market conditions can always change.
While the January effect may not be as reliable as it once was, it’s still worth considering as a potential market anomaly. Investors should be aware of this historical trend and its potential impact on their investment decisions. However, it’s crucial to avoid relying solely on the January effect and to conduct thorough research and analysis before making any investment decisions.
Remember, the stock market is complex and influenced by various factors. The January effect is just one of many potential influences, and it’s essential to consider the overall market context and your individual investment goals before making any decisions.
What is the January Effect?
The January Effect is recognized as a periodic surge in stock values that occurs during the month of January. Prior to an increase in demand for stocks, prices typically drop in December, frequently as a result of tax-loss harvesting. An additional explanation for the increase in demand is the impact of year-end bonuses that people invest in the market.
- The January Effect is the propensity for stock prices to rise at the start of the year, especially in January.
- Tax-loss harvesting, consumer sentiment, year-end bonuses, improving year-end report performances, and other factors are blamed for the January Effect.
- When comparing the historical values of the Russell 2000 and Russell 1000, it is clear that small-cap stocks are more affected by the January Effect than large-cap stocks.
Understanding the January Effect
Because small-cap companies have less liquidity than mid- or large-cap companies, it appears that they are more affected by the January Effect. Since efficient markets are based on the idea that higher returns can only be achieved by investing in riskier stocks, some economists argue that the January effect proves that markets are inefficient.
Data from the turn of the 20th century was analyzed, and it was discovered that several asset classes had outperformed the market in January. This finding contributed to the notion that the January Effect actually exists. But over time—particularly in the last few years—the markets have started to adapt to the phenomenon.
In addition, since the start of 2018, a greater number of people have started to use tax-sheltered retirement plans, meaning they have fewer reasons to sell them at the end of the year in order to realize a tax loss.

While any movement in stocks due to a concerted trend by individual investors is not impossible, it does seem unlikely in a market where institutional and high-frequency traders exist. A third potential explanation for the January Effect is portfolio rebalancing, a common theory in the 1970s and 1980s when the January Effect was strongest.
Why do stocks outperform in January?
Stocks tend to outperform in January — in a well-known market mystery that still defies clear explanation. Why it matters: The so-called January effect is a seasonal stock market behavior that runs counter to the “efficient market hypothesis” which says stock prices are fundamentally random and unpredictable.
What drives the January effect stock market anomalies?
In January, prices recover when buying picks up again. Another potential driver of the January Effect stock market anomalies is the year-end bonus. Once they have extra cash available, investors often plow money into the markets and drive stock prices higher. There’s also a possibility that investor psychology drives much of the phenomenon.
Do Stocks go up in January?
In recent years, the effect has not always worked, and in many years, investors have lost money in January. In 1942, investment banker Sidney Wachtel noticed that stocks tended to go up in January more than in other months. Academics confirmed this theory over the years in U.S. stocks, other asset classes, and other markets.
