Abstract

This study specifically aims to analyze the effects of inflation, interest rates, exchange rates, profitability ratios (ROI, OPM, GPM), and liquidity ratios (Quick Ratio, Cash Ratio) on the stock price of PT Bank Central Asia Tbk (BBCA) during the period from January 2022 to December 2024. A total of 36 monthly secondary data observations were collected using a saturated sampling technique, where the entire population within the study period was used as the sample. The analysis was conducted using multiple linear regression based on time series data, preceded by classical assumption tests (normality, multicollinearity, heteroscedasticity, and autocorrelation) to ensure the model’s validity. The results showed that interest rates, ROI, OPM, Quick Ratio, and Cash Ratio had a significant effect on BBCA’s stock price, with coefficients ranging from 0.15 to 0.42 (p-value < 0.05), while inflation, exchange rates, and GPM were not significant (p-value > 0.05). These findings confirm that internal factors (profitability and liquidity) and external factors (interest rates) play a more dominant role in influencing BBCA’s stock price. Theoretical and practical implications are provided for investors and management, along with a novel contribution through the integration of time series analysis and classical assumption testing in the post-pandemic period.
