This study aims to examine the effect of Return on Equity (ROE) and Debt to Equity Ratio (DER) on stock prices, both partially and simultaneously, at PT Aneka Tambang Tbk during the 2019–2024 period. The approach used is quantitative, utilizing secondary data obtained from the company's financial reports and public financial platforms. This study utilized 24 quarterly observations. The analysis was conducted using multiple linear regression supported by classical assumption tests, including tests for normality, autocorrelation, heteroscedasticity, and multicollinearity. The results indicate that ROE has no significant effect on stock prices, partially, as indicated by a t-value of -0.866 with a significance level of 0.396 >0.05. Conversely, DER has a significant effect on stock prices, with a t-value of 2.875 and a significance level of 0.009 <0.05. Simultaneously, ROE and DER are proven to have a significant effect on stock prices. The coefficient of determination (R²) of 0.423 indicates that these two variables explain 42.3% of the variation in stock prices, while the remaining 57.7% is influenced by factors outside the research model. This study also considers public policy perspectives and socioeconomic conditions as external factors influencing investor perceptions.
