Abstract

This study aims to examine the relationship between financial ratios and stock prices. The financial ratios include return on assets (ROA), return on equity (ROE), and earnings per share (EPS). The research tests the relationship and explanatory ability of financial ratios in explaining stock prices through multiple regression analysis. The sample comprises 88 companies listed on the Stock Exchange of Thailand in the industrial products business sector. Data were collected from financial statements for the fiscal year 2024. The results, based on the Sig Values, show that: 1) For the overall industry product sector, Return on Equity and Earnings Per Share have a significant relationship with stock prices. In the Automotive business, Return on Asset, Return on Equity, and Earnings Per Share have a significant relationship with stock prices. For the Industrial Materials & Machinery business, Return on Equity and Earnings Per Share have a significant relationship with stock prices. In the Petrochemicals & Chemicals business, Return on Asset and Earnings Per Share have a significant relationship with stock prices. For the Packaging business, Return on Equity and Earnings Per Share have a significant relationship with stock prices. In the Steel & Metal Products business, Return on Asset and Earnings Per Share have a significant relationship with stock prices. 2) The ability of financial ratios to explain stock prices, as measured by the coefficient of determination (Adjusted R²), shows that in the Automotive business and the Industrial Materials & Machinery business, the independent variables can explain stock prices at 61.30% and 92.30% respectively. For the overall industry product sector, Petrochemicals & Chemicals business, Packaging business, and Steel & Metal Products business, the values are 51.30%, 53.50%, 58.20%, and 37.90% respectively, indicating that the independent variables cannot adequately explain stock prices, as their coefficients of determination (Adjusted R²) are below 0.60 or 60 percent.
