From that regression model and analysis, it will draw leadership features, strengths of this industrial leader. The results of quantitative research, in a ten factor model, show that the decrease in GDP growth and risk free rate, inflation and increase in net sale will have a significant effect and increase VNM net profit, with the highest impact coefficient, the second is decreasing cost. This research finding and recommended policy also can be used as reference in policy for F&B system in many developing countries.

Artificial neural networks are non-linear models that can be trained to extract hidden structures and relationships that govern the data. They can be used for analyzing relations among economic and financial phenomena. In the paper we discuss our research on application of three forecasting methods. These methods are: econometric model, AR(3) and the back propagation algorithm. The prediction of share prices of three companies listed on the Warsaw Stock Exchange was made. The accuracy of forecasting was evaluated in terms of percentage errors MAPE and RASE.
