1959 book on portfolio selection. Here he provides an extended and detailed development of Markowitz’s ~1952! mean-variance model of portfolio choice, purposely designed for access by readers with a modest quantitative back- ground. In view of the then recently completed work of von Neumann and...
~2! Markowitz actually recommends semi-variance as a replacement for variance as a mea- sure of risk on the grounds that it is realistically superior and investigates its properties and optimal portfolio computing procedures. ~3! He outlines the diagonal or market model in an extended footnote ...

Therefore, we incorporate this feature, using a realistic off-the-shelf transaction-cost model from the literature. Concerning (ii), few portfolio managers in the real world ignore transaction costs at the portfolio-selection stage and simply pay them after the fact. Doing so can be expected to...
Next, we investigate the impact of the proposed method on the quality of the optimal solution obtained using several examples of the optimal portfolio selection according to the Markowitz model. The influence of hierarchical clustering parameters (intercluster distance metrics and clustering threshold ...
(MV) optimization model by making two adjustments based, on the one hand, on a behavioral decision-making theory and investor psychology, called the behavioral mean-variance (BMV) approach, and on the other hand, by using the copula theory to extract the portfolio asset dependence structures, ...
Most heuristic models performed very close to the optimal solution in the experiment, indicating that the heuristics model could capture the tradeoff between improving the position of assets and reducing the transaction costs. Li et al. (2015) proposed a specific portfolio selection approach using ...
