Stock Portfolio Optimization Using Water Cycle Algorithm (Comparative Approach)
Authors
Abstract:
Portfolio selection process is a subject focused by many researchers. Various criteria involved in this process have undergone alterations over time, necessitating the use of appropriate investment decision support tools. An optimization approach used in different sciences is using meta-heuristic algorithms. In the present study, using Water Cycle Algorithm (WCA), a model was introduced for selecting the optimal portfolio, and then the obtained results were compared with those obtained from Harmony Search (HS) and Imperialist Competitive Algorithm (ICA). For this purpose, using the data of 10-month (April 2016 to January 2017) returns of 50 top companies in the Stock Exchange Market of Iran, the optimal portfolio was estimated using the above-mentioned algorithms with the aim of maximizing profit and minimizing risk, and then the optimal portfolios obtained from these algorithms were compared with each other. Results of implementing these algorithms indicated that despite the high capability of the studied algorithms to optimize the portfolios, WCA algorithm had higher capability of portfolio optimization than the other ones

Stock portfolio selection is a classic problem in finance, and it involves deciding how to allocate an institution’s or an individual’s wealth to a number of stocks, with certain investment objectives (return and risk). In this paper, we adopt the classical Markowitz mean-variance model and consider an additional common realistic constraint, namely, the cardinality constraint. Thus, stock portf...

Once it is decided that investment is to be made in the stock, the obvious question which arises is: which all stocks should be purchased? Past performance will not guarantee the future, but it is still worthwhile to evaluate the investments based on their ability to deliver consistent returns with minimal risk. Therefore, the ability to generate most profitable return from short term stock tra...
