## Optimal Investment Strategy 最佳投资策略

We study the properties of the Bellman operator in the problem of an optimal investment strategy.^{[1]}It turns out that the optimal investment strategy is given by a piecewise monotone and continuously differentiable function of the current drawdown.

^{[2]}Finally, we calculate the probability that the optimal investment strategy will be implemented.

^{[3]}We derive the optimal investment strategy and present a closed form mean-variance efficient frontier.

^{[4]}Besides optimality results in a fairly general surplus optimization setting, we obtain closed-form solutions for the optimal investment strategy for various specific liability models, which include the cases of index-linked and performance-linked liabilities and liabilities which are completely or only partially hedgeable.

^{[5]}Hence, it is a challenge to solve stock portfolio allocation wherein an optimal investment strategy must be found for a curated collection of stocks that effectively maximizes return while minimizing the risk involved.

^{[6]}In article we consider a problem of optimal investment strategy by a commercial bank building.

^{[7]}By the stochastic dynamic programming approach and Hamilton-Jacobi-Bellman (HJB) equation, we derive closed-form expressions for the value function and corresponding robust optimal investment strategy in each problem.

^{[10]}The Monte Carlo simulation is employed to approximate the expected values and variances of the complicated random returns, and the Monte Carlo simulation based particle swarm optimization algorithm (MCPSO) is designed to obtain the optimal investment strategy.

^{[11]}I show that models of investment under uncertainty with a TTB, and models of investment under uncertainty with market incompleteness and risk aversion, ought not to be mutually exclusive as they have been in research to date because the recognised results of market incompleteness and risk aversion on the optimal investment strategy are challenged when we incorporate a TTB feature.

^{[12]}Interestingly, the optimal investment strategy displays a very intuitive dependence on current volatility levels, a trend which has not been previously reported in the literature of stochastic volatility models.

^{[13]}In contrast, in dynamic or multi-period MV portfolio optimization settings, preliminary numerical results show that MV investment outcomes can be remarkably robust to model misspecification errors, which arise when the investor derives an optimal investment strategy based on some chosen model for the underlying asset dynamics (the investor model), but implements this strategy in a market driven by potentially completely different dynamics (the true model).

^{[14]}Explicit formulas for the optimal investment strategy are presented.

^{[15]}In this note we characterize the optimal investment strategy for the choice between different types of power production technologies: the coal-fired plants as the representative power generation source for traditional fuels and wind power for the representative renewable source.

^{[19]}Finally, we use simulation based analysis to examine the impact of RTM on the optimal investment strategy.

^{[20]}Then, we characterize the optimal investment strategy and the optimal proportional level of reinsurance.

^{[21]}Within the framework of this article, the mechanisms for constructing and researching the game model for choosing the investor's optimal investment strategy in various information conditions are disclosed: building many players, building many players' strategies, the option of formalizing the payment function in the form of a game matrix, many optimality criteria, methods of justifying the choice of the strategy optimality criterion.

^{[22]}Our investigation reveals that the inflation has significant negative effect on optimal investment strategy, particularly, the CCRA is not constant with the investment strategy since the inflation parameters and coefficient of CRRA utility function have insignificant input on the investment strategy.

^{[5]}A mathematical model of a dynamic portfolio strategy is developed, and guidelines for framing a long-term investment strategy based on the current state of the investment market are formalized.

^{[6]}Therefore, the scientific contribution of this article is an effective use of a hybrid model that combines a quantitative method – such as the Net Present Value (NPV), and a qualitative method - such as the Analytical Hierarchy Process (AHP) in a multi criteria decision-making environment which proved that choosing the perennial plantations is a better long term investment strategy then the classic crop production.
