using advanced techniques of econometrics and a metaheuristic optimization approach, this study attempts to evaluate the potential advantages of international portfolio diversification for east asian international investors when investing in the middle eastern emerging markets. overall, the results of both econometric and the metaheuristic optimization methods are supporting each other. finding...

Investment portfolios should be rebalanced to take account of changing market conditions and changes in funding. Standard mean-variance (MV) portfolio selection methods are not appropriate for portfolio rebalancing, as the initial portfolio, change in funding and transaction costs are not considered. A quadratic mixed integer programming portfolio rebalancing model, which takes account of these...

Since the 1960s, lots of scholars had begun to research in the portfolio selections based on the theory of mean-variance of Markowitz portfolio and relevant methods. All of these studies are under certainly of the assumption term, and then the researchers can get efficient set of portfolio selection. However, alone with the finance environment increasing of complexity, it is becoming more compl...

The focal objective of this study is to analyze and explore the Co-movement of Pakistan stock market (KSE-100) with the stock market of developed countries (US, UK, Canada, Australia, Germany, Japan, France and Neither land) which have portfolio investment in Pakistan by applying co-integration approach using Johansen and Juselius multivariate and bi variate co-integration. Secondary data of st...

The purpose of this study is to develop portfolio optimization and assets allocation using our proposed models. The study is based on a non-parametric efficiency analysis tool, namely Data Envelopment Analysis (DEA). Conventional DEA models assume non-negative data for inputs and outputs. However, many of these data take the negative value, therefore we propose the MeanSharp-βRisk (MShβR) model...

We study in this paper the portfolio selection problem with a stock index and European style options on the index. A refined mean-variance methodology is adopted in the study. Single-stage and two-stage investment models are studied and solved. In the later case a scenario tree and stochastic programming formulation are used. Explicit forms of the optimal portfolio and its corresponding efficie...
