The evolution of the Bucharest Stock Exchange is influenced by a number of factors that have a more or less significant impact upon the trend this market follows. The implementing of stimulating policies in what concerns the development of the financial market, strictly connected to the development of the national economy, implies both the awareness of these factors existence as well as the need of evaluating the impact they have. The purpose of the present paper is to identify and quantify the impact of the macroeconomic variables, such as the inflation rate, interest rate or exchange rate upon the evolution of the Bucharest Stock Exchange.
