• ON ROUGH INTERVAL QUADRATIC PROGRAMMING APPROACH FOR MINIMIZING THE TOTAL VARIABLILITY IN THE FUTURE PAYMENTS TO PROTFOLIO SELECTION PROBLEM

Abstract

In portfolio selection problem (PSP), the expected at return, risk, liquidity can not be predicted accurately. So, the investor generally makes his portfolio choice according to his knowledge and his economic wisdom. Thus, deterministic portfolio selection is not a sensible option for the investor. Because of the existence of several non-stochastic factors in stock market, uncertain portfolio selection models have been proposed by many authors.
