Building on the earlier work of Detemple (1986), Dothan and Feldman (1986), and Gennotte (1986), it is shown that the possibility of future learning about the mean return on the ris...

We propose a novel portfolio evaluation method, distance-based approach, which directly evaluates the composition rather than returns. In this we consider as an estimator for in-sample tangency portfolio, define optimal reference portfolio. then evaluate by computing its vector distance to search of proper performance measure, choose four representative distances and compare their suitability n...

Therefore, it is necessary to determine the integer value of assets when we deal with portfolio optimization. In addition, one of the main concerns with most portfolio optimization is associated with the type of constraints considered in different models. In many cases, the resulted p...
