ABSTRACT
Using the method of mathematical modelling, this study takes authentic public securities data as the basis to test the MA expert system and MACD expert system. By taking annual net profit margin, rate of return and winning rate as the management goal, the two directional indexes are calculated and analysed, thus obtaining the MA expert system and MACD expert system. Compared with the winning rate of one-time buy-in of all funds, step-by-step buy-in with 30% funds can merely increase 1% and 6.31% respectively. However, the annual rate of return and net profit margin drop significantly to 26.36% and 50.93%, and the number of annual transactions is reduced by 762.4 and 758.4 times. According to the market implication of this calculation result, the method of funds management is meaningless for MA expert system and MACD expert system.
