Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  consider in this paper the mean–variance formulation in multi-period portfolio selection under no-shorting constraint. Recognizing the structure of a piecewise quadratic value function,  prove that the optimal portfolio policy is piecewise linear with respect to the current alth level, and derive the semi-analytical expression of the piecewise quadratic value function. One prominent feature of our findings is the identification of a deterministic time-varying threshold for the alth process and its implications for market settings.  also generalize our results in the mean–variance formulation to utility maximization with no-shorting constraint.
