Analysis of Monday Effect, January Effect, and Rogalski Effect on the LQ45 Index on the Indonesia Stock Exchange (2019-2021)

The stock market is known for its unpredictable behavior, often exhibiting anomalies that deviate from the efficient market theory. This theory suggests that stock prices should reflect all available information, but in reality, market anomalies can have a significant impact on stock returns. This study focuses on three categories of seasonal anomalies: the Monday effect, the January Effect, and the Rogalski Effect. By analyzing company data listed in the LQ45 index on the Indonesia Stock Exchange during the 2019 to 2021 period, researchers aimed to identify the impact of each of these anomalies on stock returns.

Understanding Market Anomalies

Market anomalies are deviations from the efficient market theory, where stock prices do not reflect all available information. These anomalies can be seasonal, meaning they occur at specific times of the year, or non-seasonal, occurring randomly. The three anomalies studied in this research are:

  • Monday Effect: This anomaly refers to the phenomenon where stock prices tend to decrease on Mondays. This may be caused by more optimistic investor psychology when starting the week, but then ends with more sales when investors analyze the latest news and data after weekends.
  • January Effect: Unlike the Monday effect, the January effect shows that stock returns in January tend to be higher. This may be related to the behavior of investors who purchase new shares after the end of the year to avoid taxes or because of greater expectations of company performance in the new year.
  • Rogalski Effect: Research found that the Rogalski effect also had a significant positive impact on stock returns. This shows the pattern in returning shares that can be utilized by investors to get better results.

Methodology and Results

This study used the Partial Least Square (PLS) method through the SmartPLS application to analyze the data of 33 companies listed in the LQ45 index on the Indonesia Stock Exchange during the 2019 to 2021 period. The results showed that:

  • The Monday effect had a significant negative influence on the return of LQ45 company shares during the 2019-2021 period.
  • The January effect and the Rogalski effect gave a significant positive influence on the return of LQ45 company shares in the same period.

Implications for Investors

The findings of this study provide important insights for market participants and investors. Understanding stock price behavior based on seasonal anomalies can be a smarter investment strategy. By paying attention to certain days and months that produce the highest or lowest return, investors can make better investment decisions and maximize their profits.

In the world of investment, information is the key. By knowing market anomalies such as the Monday effect, the January effect, and the Rogalski effect, investors can set their investment strategies to avoid losses and take advantage of profit opportunities that may not be seen by other investors. Therefore, this research is not only relevant for academics but also for practitioners operating in the capital market.

Impact of Monday Effect, January Effect, and Rogalski Effect

Monday Effect

The results showed that shares tend to decrease in prices on Monday. This may be caused by more optimistic investor psychology when starting the week, but then ends with more sales when investors analyze the latest news and data after weekends. Investors should consider not investing on Monday to minimize losses.

January Effect

Unlike the Monday effect, the January effect shows that stock returns in January tend to be higher. This may be related to the behavior of investors who purchase new shares after the end of the year to avoid taxes or because of greater expectations of company performance in the new year. Investors are advised to take advantage of this momentum by investing at the beginning of the year.

Rogalski Effect

Research found that the Rogalski effect also had a significant positive impact on stock returns. This shows the pattern in returning shares that can be utilized by investors to get better results. Knowing the moment when returning shares usually increases can provide opportunities for investors to enter and exit the market more strategically.

Implications for Investors

The findings of this study provide important insights for market participants and investors. Understanding stock price behavior based on seasonal anomalies can be a smarter investment strategy. By paying attention to certain days and months that produce the highest or lowest return, investors can make better investment decisions and maximize their profits.
