Understanding the January Effect on the Stock Market

Many individual investors and market scholars have called the January effect a hypothesis; it could also be said to follow the same drive as the calendar effects. For the January effect to be efficient and investment strategy effective, the market needs to be inefficient.

It is important to note that the January effect affects the small caps market. Unlike the mid or the large cap stocks market, the January effect is better off with the small caps because of its low level of liquidity in a broader market.

It is known that the asset classes have been outperforming in the market during January but mostly towards the middle of this month. This data was gathered before the beginning of the 20th century, and it is still in place today.

In the year 1942, the January effect was first noticed by an investment banker Sidney Wachtel. The effect continued to be in place since then until recent years. This is due to the nature of the market because the market has adjusted to the January effects.

In the year 2021, the January effect was said to be of less importance because of the use of tax-sheltered retirement plans. In this regard, the investors and traders have no reason to sell their stocks for a tax loss at the end of the year.

January Effect Drivers and Stock Prices

One of the major drivers of the January effect is tax planning. In other to reduce the tax bill that is likely to pile up, investors sell stocks that seem to be underperforming in December.

This act locks in the capital loss that would have accumulated; it also leads to an impermanent dip. The January effects then helps stock performance by recovering the dipped prices.

Another driver of the January effect is the end of year bonuses given to workers. With the availability of cash (end-of-year bonus), these investors put their money in the stock market and help stock prices go higher.

Some scholars or investors are of believing that investor psychology also leads to the January effects. Most individuals believe that new they should start the new year with new things, hence they buy some stocks to be in business.

These individuals also sell out their stocks at year-end to start anew in the year to come – this is a good financial planning.

How Does the January Effect Occur in Tax Loss Harvesting?

Investors and traders have observed the January effect over the years. This observation started shortly before the 20th century but has become subtle.

The decline in the stocks has always been reasonable in January. There has never been a record of a sharp decline in stocks over the years.

One thing about the January effect is that no one has any idea why the January effects will happen; prediction is very rare. The engagement of tax-loss harvesting helps in the sell-off of stocks in December and offsets the capital gains.

Why Does the January Effect Happen?

The hypothesis behind the January effect makes people think that it always happens. In the real sense of it, the January effects doesn’t happen all the time and individuals have no reason why it does.

This is because traders and investors tend to sell some positions that have an order decline; the whole event is to handle the capital loss in the calendar effect taxes.

There is a theory of income tax that says that investors hold on to more small-cap stocks to sell them in December. This hold is to enable a claim of capital loss on investors' taxes. These investors then invest in the stock market during the new year thereby pushing the prices of stocks high for small-cap companies.

Others say the January effects is produced by people receiving year-end bonuses in January and investing them in the stock market, or by employee pension and 401k plan contributions at the end of the year.
