Analysis of the Effect of Return on Assets (ROA), Debt to Equity Ratio (DER), and Inflation on the Stock Prices of Automotive Industry and Component Companies Listed on the IDX for the 2020-2024 Period

This research aims to analyze the effect of Return on Assets (ROA), Debt to Equity Ratio (DER), and inflation on the share prices of automotive and component industry companies listed on the Indonesia Stock Exchange (IDX) for the 2020-2024 period. The research method uses a quantitative approach with panel data regression analysis. The research population includes all automotive and component industry companies listed on the IDX, with a sample of 13 companies selected using purposive sampling, resulting in 65 observations. Secondary data were collected from the companies' financial statements, inflation data from BPS, and stock price data from the IDX. The analysis technique used panel data regression with a random effect model after conducting the Chow, Hausman, and Lagrange Multiplier tests. The results of the study show that simultaneously ROA, DER, and inflation have a significant effect on stock prices, with an F-value of 3.366161 and a p-value of 0.000. Partially, ROA has a positive and significant effect on stock price, with a coefficient of 122.0658 and a p-value of 0.000. Meanwhile, DER and inflation had no significant effect on stock price, with p-values of 0.2578 and 0.5027, respectively. The determination coefficient of 14.2035% indicates that the independent variables explain 14.2035% of the variation in stock prices, while the remaining 85.7965% is influenced by other factors outside the research model.
