In this context, performance measurement remains a constant concern of the entire economic sector that can ensure the progress of an entity. The purpose of this paper is to carry out a dynamic analysis over an 11-year period of the profit margin at the level of the economic agents in Constanta County whose main object of activity is, according to the NACE classification, Real Estate activities/transactions. In the analyzed period, the year 2015 stands out, in which the resumption of lending for large projects and the return of investor confidence in the real estate sector created a contagious euphoria on the market which, coupled with the income accumulated in the crisis by investors looking for profitable capital investments, led to the emergence of a wave of acquisitions, thus stimulating the real estate transactions market.
