Understanding the January Effect: Stock Market Trends & Causes

The January Effect is known to be a seasonal increase in stock prices throughout the month of January. The increase in demand for stocks is often preceded by a decrease in price during the month of December, often due to tax-loss harvesting. An alternative reason for the rise in demand is the effect of year-end bonuses individuals receive that are invested in the market.

 

Understanding the January Effect: Stock Market Trends & Causes

 

Summary

  • The January Effect is a tendency for increases in stock prices during the beginning of the year, particularly in the month of January.
  • The cause behind the January Effect is attributed to tax-loss harvesting, consumer sentiment, year-end bonuses, raising year-end report performances, and more.
  • The January Effect appears to affect small-cap stocksSmall Cap StockA small cap stock is a stock of a publicly traded company whose market capitalization ranges from $300 million to approximately $2 billion. more than large-cap stocks, which is apparent when comparing the historical values of the Russell 2000 with the Russell 1000.

 

Understanding the January Effect

The January Effect appears to affect small-cap companies more than mid- or large-cap companies due to their lower liquidityLiquidityIn financial markets, liquidity refers to how quickly an investment can be sold without negatively impacting its price. The more liquid an investment is, the more quickly it can be sold (and vice versa), and the easier it is to sell it for fair value. All else being equal, more liquid assets trade at a premium and illiquid assets trade at a discount.. Some economists postulate that the January effect substantiates the fact that markets are inefficient, as efficient markets stem from the belief that higher returns are only possible by taking on higher-risk stocks.

Analyzing data from the beginning of the 20th century, it has been found that a variety of asset classes had outperformed the market during the month of January, which led to the belief that the January Effect indeed exists. However, over time, especially in recent years, the markets have begun to adjust to the phenomenon.

Furthermore, at the beginning of 2018, more individuals have begun using tax-sheltered retirement plans and have less purpose to sell at the end of the year to receive a tax loss.

 

Additional Drivers Behind the January Effect

Beyond the hypothesis of tax-loss harvesting and bonuses, it appears that the January Effect may also be driven by consumer sentiment. As January is the beginning of a new year, many investors believe that the start of the year is the best time to begin investing for their future, under a clean slate.

Another reason may perhaps stem from the fact that mutual fund managersFamous Fund ManagersThe following article lists some of the fund managers that have been regarded as exceptional.

Past Studies and Comments

Based on a study that analyzed data between 1904 and 1974, the average return for stocks during January was approximately five times greater than any other remaining months throughout the year. In fact, Salomon Smith Barney performed an analysis behind stock performance between 1972 to 2002 and learned that small-cap stocks outperformed large-cap stocks during January.

Efficient market theorists believe that modern markets are too efficient for the January Effect to affect trading. That is, investors would anticipate such an effect and purchase stocks in December, as others begin to sell, which would ultimately offset the discrepancy and result in equilibrium.
