This study employed a quantitative rfesearch method using descriptive statistical analysis, classical assumption tests, multiple linear regression analysis, hypothesis testing consisting of partial test (T-test) and simultaneous tests (F-test), as well as the coefficient of determination test using SPSS version 27. The results indicate that the Economic Growth variable (X1) has no significant effect on Stock Prices (Y), with a significant value of 0.846 > 0.05. (X2) has no significant effect on Stock Prices (Y), with a significance value of 0.757 < 0.05.

This indicates that the independent variables are able to explain 99.7% of the variation in the dependent variable, while the remaining 0.3 % is explained by other variables outside the scope of this study.
