Though mean-variance portfolio construction has been a rather popular criterion in portfolio investment, it is not the only principle when selecting portfolio. There are limitations in the mean-variance concept of Markowitz’s portfolio theory. The mean-variance approach has limited generality because the mean-variance approach will only lead to optimal decisions if utility functions are quadratic or if investment returns are jointly elliptically or spherically distributed [22] and [23]. In addition, with Markowitz model, one cannot always tell if one efficient portfolio is better than another because a portfolio with a relatively high variance will be relatively safe if its expected value is sufficiently high [11].
