Understanding the January Effect and How It Impacts Trading

Carvana was one of the worst-performing stocks in the market throughout 2022. By December 2022, it had plummeted roughly 98% from its all-time high. Investors who held the stock at a loss were aggressively selling it in December to lock in those losses for tax deductions. As a result, the stock reached an extreme low of around $3.55 in late December. When the new year set in, the tax harvesting-led selling pressure waned. Investors saw this as an opportunity to buy the dip. As a result, Carvana’s stock price more than doubled in January 2023, rallying from under $5 to over $10 by the end of the month.

Carvana’s stock performance perfectly illustrates the January Effect. The bounce happened almost immediately as the new year began, independent of any major specific news from the company itself in those first few days. However, this is an extreme case. Not all stocks impacted by the January Effect see such large gains. Yet, the seasonal trend might be worth exploring if it aligns with your overall trading strategy and goals.

What is the January Effect?

The January Effect is a market hypothesis. It suggests that stocks, especially small caps, tend to rise in January more than in other months. This was first noticed in 1942 by an investment banker named Sidney Wachtel. He looked at market data going back to 1925 and found that smaller companies often outperformed the broader market at the start of the year.

The effect is not always consistent. Some years show strong January gains, while other years might show flat or negative returns. However, the historical pattern is strong enough that it remains a popular topic in stock trading.

Why Does the January Effect Happen?

There are several reasons for the January Effect.

Tax-Loss Harvesting

This is the most common explanation. In December, investors often sell stocks that have lost value to claim a capital loss on their taxes. This selling pressure drives the prices of those stocks down even further. Once the new year begins, investors buy these stocks back. This sudden increase in buying demand pushes prices up.

Year-End Bonuses

Many people receive holiday bonuses or year-end financial gifts in December. When January arrives, they often deposit this extra cash into their investment accounts. This influx of new money into the market can help lift stock prices.

Investor Psychology

The start of a new year feels like a fresh start. Investors often make New Year’s resolutions to improve their finances. This optimism can lead to more stock buying activity in January.

“Window Dressing” by Fund Managers

Mutual fund managers want their year-end reports to look good. They may sell underperforming stocks in December to prevent them from showing up on the list of holdings. In January, they feel free to buy these riskier or beaten-down stocks again.

Does the January Effect Still Work?

The stock market changes over time. Strategies that worked decades ago may not work as well today.

Recent data suggests that the January Effect is weakening. The markets are more efficient now. Information travels instantly. Since so many people know about the January Effect, they often try to buy stocks in December to “beat the crowd.” This shifts the price rise earlier, sometimes into December itself.

However, the effect is still visible in specific areas. It is most noticeable in small-cap stocks. Large companies, like Apple or Microsoft, are less likely to show a big January rally solely due to this effect.

Tips to Trade the January Effect

If you want to capture opportunities emerging from this seasonality, you might need to adjust your trading strategy around this phenomenon. But be careful. Don’t buy stocks just because it is January. Here are specific tips to help you navigate this period.

Focus on Small-Cap Stocks

History shows that small companies benefit the most from the January Effect. These stocks are often less liquid. This means a small amount of buying can move their price up quickly. Look for solid small-cap companies that had a rough performance the previous year.

Watch for “Tax-Loss” Candidates

Look for stocks that were sold off heavily in November and December. If a stock has good fundamentals but its price dropped simply because investors were harvesting tax losses, it might bounce back in January.

Enter Early

Don’t wait until January 2 to buy. By then, the smart money has often already entered the trade. A common strategy is to start buying these beaten-down stocks in mid-to-late December. This positions traders to catch the wave as the new year begins.

Use Stop-Loss Orders

The January Effect is not 100% reliable. If the market overall is bearish, even a seasonal trend might not save a bad trade. Always use stop-loss orders. This limits your risk if the stock price continues to fall, instead of rising.

Don’t Ignore Fundamentals

A cheap stock is sometimes cheap for a reason. Before you buy a beaten-down stock, check the company’s health. Do they have too much debt? Are their sales shrinking? If the company is failing, a seasonal bump in January won’t last long. Only trade stocks that your analysis shows have fundamental value.

To Sum Up

• Historically, the stock markets tend to see an upswing as the new year begins.
• This is especially visible among mid- and small-cap stocks.
• The December selling pressure on certain stocks occurs due to tax loss harvesting, year-end bonuses being invested, investor sentiment and window dressing by fund managers.
• This selling pressure abates in the new year.
• To make the most of the January Effect, focus on small-cap stocks, watch for “tax-loss” candidates and enter early.
• Don’t forget to use stop-loss orders or ignore fundamentals.
