Abstract

Seasonal anomalies in the capital market continue to show mixed empirical findings, making stock return patterns around the turn of the year an important topic for investigation. This study aims to analyze differences in stock actual returns around the year-end period among companies listed in the IDX30 Index during 2023–2025. A quantitative comparative approach was employed using weekly actual return data from 21 companies selected through purposive sampling. Data were analyzed using descriptive statistics, the Shapiro–Wilk normality test, the Kruskal–Wallis test, and the Mann–Whitney U post hoc test. The results indicate significant differences in actual returns across the observed periods, suggesting seasonal variations in stock return patterns around the turn of the year. However, these findings should not be interpreted as direct confirmation of the Turn of the Year Effect. This study contributes empirical evidence to the literature on seasonal anomalies in the Indonesian capital market and provides a basis for further research using more comprehensive analytical approaches.

Abstract

This study was conducted to examine the effect of profitability, measured by Return on Assets (ROA), and leverage, measured by Debt to Equity Ratio (DER), on stock returns in transportation sub-sector companies listed on the Indonesia Stock Exchange during the 2020–2024 period. The data were analyzed using multiple linear regression with the assistance of IBM SPSS software. The classical assumption tests showed that the residuals were normally distributed, with no indications of multicollinearity, heteroscedasticity, or autocorrelation. The results of the partial test (t-test) indicated that both ROA and DER had no significant effect on stock returns. Furthermore, the simultaneous test (F-test) showed that ROA and DER did not significantly affect stock returns. The coefficient of determination (R²) revealed that the ability of ROA and DER to explain variations in stock returns was very low, indicating that most variations in stock returns were influenced by other factors outside the model. Therefore, profitability (ROA) and leverage (DER) were not determinants of stock returns in transportation sub-sector companies during the research period.
