Portfolio Approach To Study

Investment originally is one of the tasks in the field of economy, and it seems that it has no relations with engineering. But, by using the knowledge of systems engineering, scientists of today 's can design many models of investment process and choose the optimum scheme after analyzing these models. We define this scheme as investment combination, or investment combination project.In this paper, the concept x study objects and methods of the investment combination are recounted. At the same time, the advantages and the disadvantages of the traditional one are introduced. And, the investment combination investigation methods and management models are given. We also present some common theories (such as MA, MACD, WMS, KDJ, RSI) to design the investment combination. The mean variance, capital rated and capital interest arbitrage are also devised.For the practical necessary, especially the geometry increment, the best choice and the risk and anticipated yield models are shown in the paper. By studying a series of investment combination models, we hope they can serve the society very well.
