Analysis of the grey matrix game model in stock speculation for immediate price-margin based on grey information

In stock market, game behaviors of investors seeking immediate price-margin could be described by model of matrix game. However, due to such factors as limitation of human knowledge, incompletion of information and structural and random fluctuation of system, it´s impossible for matrix of future yield to be completely accurate. Applying grey theory, the thesis takes a new approach to analyze deeply and study decision making in the field of grey matrix for immediate price margin for stock investors based upon grey information. Firstly, we define concepts such as preceded grey payoff matrix by players concerned and the set of strategies. Based on this, the thesis gives proof of the sufficient condition in one-side conservation solution, the general solutions, and optional solution, in case of grey pure strategy. The constructive proves have provided stock speculator with the solution in the grey matrix game for immediate price-margin.
