Abstract

This study examines the relationship of Market Capitalization and Company Size with Stock Returns at PT Sariguna Primatirta Tbk during 2017–2025. A quantitative approach was employed using secondary data from annual financial reports and historical stock prices. The data comprised nine annual observations and were analyzed using multiple linear regression with IBM SPSS Statistics 25. The results indicate that neither Market Capitalization nor Company Size is a statistically significant predictor of Stock Returns individually or jointly within the research model. The (R^2) value of 0.008 indicates that the model explains 0.8% of the variation in Stock Returns. These findings should be interpreted cautiously because the study is limited to nine annual observations from a single company, which restricts the generalizability of the results. Future research could include more companies, longer observation periods, and additional variables
