The original portfolio may be any portfolio that the investor holds prior to obtaining the information and need not be a market index fund; whereas, the new portfolio can be thought of as the optimal combination of the old portfolio and the securities that are affected by the event information. During the process of constructing the optimal portfolio, several factors and investment characteristics are considered.

This work solves the portfolio optimization problem in a continuous-time Markov-modulated financial market by stochastic control methods and shows that state uncertainty have a great influence on optimal portfolio choice. The proposed strategy also considers the effects of portfolio rearrangement costs on growth optimality and recommends a suboptimal portfolio for discrete investment periods. The overperformance of the proposed optimal portfolio, applied to cross-asset trading universe, is con rmed by empirical backtests. This paper attempts to maximize the expected return and minimize the variance of the portfolio by using Markowitz's portfolio selection model and a three-objective linear programming model to allocate different percentage of weight to different assets to obtain an optimal/feasible portfolio of the financial sector of the Nigerian stock exchange (NSE). Optimal portfolios typically include inconvenient and insignificant asset weights, make for.
