Portfolio adjusting model using uncertainty theory: an application to real finance market

This paper deals with a mean-semi absolute deviation-skewness model for portfolio selection, allowing adjustment of stocks and transaction costs in an uncertain environment. For this, the stock returns are regarded as uncertain variables and their distributions are assumed to be zigzag. The solution method of our proposed model is illustrated by a numerical example. The example given has been constructed by taking secondary data from the Bombay Stock Exchange (BSE), India.
