A PROFITABILITY REGRESSION MODEL IN FINANCIAL COMMUNICATION OF ROMANIAN STOCK EXCHANGE’S COMPANIES

Abstract

The rate of profit is one of the most important indicators for the stakeholders and shareholders of the companies in the modern economy. In the present article we clearly identified the relationship between the net profit margin and other three composite financial indicators for the companies that are included in BET Index, the most important index of the Romanian Stock Exchange. We identified the regression model that includes, with a significance level of 95%, the stockholder’s equity, long-term liabilities, provisions, deferred revenues over a year, total liabilities, working capital and current assets.

The regression model was validated by using many statistics: Multiple R, R Square, t test, F test and p-values. Finally, we obtained the complete valid regression model regarding the profitability of Romanian Stock Exchange’s companies.
