Investment Research Of Assets Combined With Adding Revenue And Multiplying Revenue

Investment objects-financial assets, is a very important part discussed in investmenttheory. The content of investment theory can be departed into pricing theory, portfoliotheory, profits and risk analyzing theory by the different research point of view. InFinancial Economics, assets have been divided into two kinds, the ones with addingrevenue and the ones with multiplying revenue, and their Mathematical formulas ofprofits, risk, optimal investment proportion, risk premium has been given. But with thedeveloping of financial market and innovating of financial assets, only use these tworevenue models to describe all the financial assets is not enough. Inspired by FinancialEconomics, this paper has expanded the financial models and come up with three newmodels: the direct mixing model, the combination mixing model and the probabilitymixing model of the adding revenue and multiplying revenue. Using the similarmethods with Financial Economics, this paper has analyzed the portfolio problems andconcluded the formulas of profits, risk, optimal investment proportion, risk premium ofthese three new models. Based on these, in the end, this paper has listed three relevantexamples. The computational procedure using of these examples, on one side haveintroduced the practical application of the formulas, on the other side, have proved theconclusions at the same time.
