The independent variables in this study are represented by Return On Assets (ROA), Return On Equity (ROE), Net Interest Margin (NIM)). The data collection method used is the library research method. The data analysis technique used is multiple linear regression and hypothesis testing using t-statistics to partially test each variable.

The data is processed using the SPSS program. The results show that partially ROA(X1) is Tcount(3.129) > Ttable(2.064), then it has a positive effect on Stock Price(Y), For ROE(X2) is Tcount(-2.677) < Ttable(2.064), then it has no effect negative to the Stock Price (Y). and for NIM(X3) is Tcount(0.708) < Ttable(2.064), then it has no positive effect on Stock Price(Y). For Simultaneous calculation (Test Statistics F), then t table of simultaneous test results Fcount(4.418) > Ttable(2.99) , then the conclusion ROA(X1), ROE(X2)d and NIM(X3) simultaneously affect stock prices (Y). For the Coefficient of Determination (R²), the independent variable affects the health level of BCA Bank as much as 35.6%, and the remaining 64.4% is affected by other variables.
