“…Portfolio Markowitz have studied by many researchers for examples : Deng, Lin, & Lo (2012) discussed about Cardinality Constraints Markowitz Portfolio Optimization problem (CCMPO problem) [4]; Evstigneev, Hens, & Schenk-Hoppé (2015) talked about the minimum variance portfolio, the return-generating self-financing portfolio involved in the solution to the Markowitz optimization problem [5]; Markowitz (2014) discussed about mean-variance approximations to expected utility [6]; Dhrymes (2017) mentioned about CAPM extending the work of Markowitz in portfolio selection, and the role played by idiosyncratic risk, and the optimal composition of efficient portfolios [7]; Leung, Ng, & Wong (2012) discussed about derives explicit formulas for the estimator of the optimal portfolio return [8]; and Park & Shin (2013) talked about stock trading model using portfolio optimization on stocks which listed in KOSPI200 from January 2007 to August 2008 [9].…”
