By this reason it is of interest to analyze the quality of such recommendations. In annotated paper it is given the special consideration to the analysis of accuracy and profitability of financial analysts’ forecasts and recommendations as well as its consensus (conflict). The accuracy and the profitability are investigated by the methods of mathematical statistics. The conflict of forecasts is estimated with the help of the theory of belief functions.
