Control policy optimization for dynamic asset allocation by using kernel principal component analysis

Coauthor: Jun-Ya Gotoh

 

Abstract:
We utilize a nonlinear control policy, which is a function of past asset returns or economic indicators, to construct a portfolio. Although the problem of selecting the best control policy from among nonlinear functions is intractable, our previous study has built a computational framework for solving this problem. Specifically, we have shown that this problem can be formulated as a convex quadratic optimization problem by using a kernel method, which is an engine for dealing with the strong nonlinearity of statistical models in machine learning. Our nonlinear control policy resulted in better investment performance than the basic model and linear control policies could give. However, it was difficult to handle a large-scale portfolio optimization problem. Thus in this presentation, we provide an efficient solution for optimization of a nonlinear control policy by using kernel principal component analysis. Computational experiments show that our solution is effective not only in reducing the CPU time but also in improving the investment performance.
