Abstract

This study aims to analyze the influence of Return on Assets and firm size on firm value within the banking sector listed on the Indonesia Stock Exchange (IDX) during the 2019–2023 period. Firm value in this study is proxied by the Price-to-Book Value (PBV) ratio. The independent variables employed are Return on asset (ROA), serving as an indicator of profitability, and firm size, measured using the natural logarithm of total assets. This study utilizes a quantitative method employing multiple linear regression analysis. The data used is secondary data derived from the banks' annual financial reports, obtained from the official IDX website and individual company publications. The sample was selected using a purposive sampling method to identify banks that met the established criteria throughout the observation period. The results indicate that, when analyzed individually, Return on Asset (ROA) does not have a significant effect on firm value. Conversely, firm size has a positive and significant effect on firm value, implying that larger firm size leads to higher investor appreciation for the company. When analyzed simultaneously, both Return on Asset (ROA) and firm size have a significant effect on firm value. Thus, it can be concluded that Return on Asset (ROA) has a positive but insignificant effect, whereas firm size has a positive and significant effect.
