Analysis of key influencing factors on the financial performance of Jakarta Islamic Index 30 industrial firms

Purpose The purpose of this paper is to investigate the impact of size, asset quality, asset management, financial risk, gross domestic product and inflation rate on the financial performance of companies listed on the Jakarta Islamic Index of 30 industrial firms. Design/methodology/approach Based on the selected criteria, this study analysed an unbalanced panel of data from 30 industrial companies on the Indonesian capital market that are members of the Jakarta Islamic index. Profitability is measured using the dependent variables return on assets (ROA), return on equity (ROE) and stock prices. The influence of explanatory variables of internal factors, namely, size, asset quality, asset management, financial risk, gross domestic product and inflation is investigated using pooled OLS, fixed and random effect estimation. Findings The empirical findings indicate that the scale of a company has a significant impact on its performance, asset quality, asset management and financial risk. GDP has a substantial impact on financial performance, particularly as measured by ROA and ROE. This study’s ramifications have substantial effects on a broad spectrum of stakeholders. The results of this study provide the general public and investors with a greater understanding of the factors that influence a company’s performance on the Jakarta Islamic Index 30.
