Abstract:

Starting from the economic and financial performance, this study proposes an analyze of the relationship between two return rates that are often used in respect of measuring the companies' performances. The development of a hypothesis, the econometric model proposed and the results come to demonstrate the existing relationship between the two rates for Petrom and Zentiva companies. The idea of this study exists due to the fact that, as far as I know, in the specificliterature there are no such studies on this theme.
