## A novel methodology for portfolio selection in fuzzy multi criteria environment using risk-benefit analysis and fractional stochastic

 Department of Industrial Engineering, Yazd University, Yazd Iran

This article proposes an efficient approach for solving portfolio type problems. It is highly suitable to help fund allocators and decision makers to set up appropriate portfolios for investors. Stock selection is based upon the risk benefits analysis using MADM approach in fuzzy environment. This sort of analysis allows decision makers to identify the list of acceptable portfolios where they can assign some portions of their asset to them. The purpose of this article is two folds; first, to introduce a methodology to select the list of stocks for investment purpose, and second, to employ a stochastic fractional programming model to assign money into selected stocks. This article proposes a hybrid methodology for finding an optimal or new optimal solution of the problem. This hybrid approach considers risks and benefits at the time of stocks prioritization. This is followed by solving a fractional programming to determine the percentages of the budget to be allocated to stocks while dealing with two sets of suitable and non-suitable stocks. For clarification purposes, a sample example problem is solved.

Portfolio risks
 Portfolio Risks Descriptions Broker (C1) Since investors in the developing countries have little access to brokers on the international markets so the risk can be relatively high for investors. Technical Analysis (C2) Access to professional technical analysts is not a simple task. This because (1) there are not too many of such analysts and (2) they are far less experienced in this task in general. Capital management (C3) Capital management techniques are related to three categories of: Tools, Objectives and Costs. More on these terminologies can be studied in the work of Amiri, et al. (2010). Trading System (C4) A good on-line trading system with fast access to internet may help capital management to access the main trading board and then buy or sell as required. Most likely in developing countries the internet access is not fast and always available for political and social reasons as it is in many middle eastern countries. Technology (C5) Due to the fact that foreign exchange is rapidly growing and will continue to do so and reaching over 3 trillion dollars (Amiri et al. 2010), hence we there is a need to spend more on technology and expect a good level of risk at any level of trading. Trading Psychology (C6) The most effective factors in trading psychology can be identified as: trading commitment, personal trading style, personal discipline, trading coach, courage, and familiar with the secrets of successful traders.

Portfolio Benefits
 Portfolio's Benefits Descriptions Dividend (C7) Dividend can be defined according to following formula where dai is the nominal annual revenue and Ph, i is the highest price of asset i in the year before. Dividend of a portfolio is defined as the weighted sum of the dividends of individual stocks in the portfolio. $d_{i}=\frac{d_{i}^{a}}{p_{i}^{h}}$ Short term and long Some researchers considered short term and long term term returns (C8) returns for 12 months performance and 36 months Related formulas for these performances are shown below where $P_{T, i}, P_{T-1, i}, P_{T-3, i}$ are defined as price of asset i at periods $T, T-1, T-3,$ respectively. The short term performance for asset $i$ is as shown below: $r_{i}^{12}=\frac{P_{T, i}-P_{T-1, i}}{P_{T-1, i}}$ The long term performance for asset i is as shown below $r_{i}^{36}=\frac{P_{T, i}-P_{T-3, i}}{P_{T-3, i}}$ Liquidity (C9) For a specific asset, liquidity is set to be a proportion of that asset which is called turnover rate. Often investors prefer to deal with greater liquidity. Standard and Poor's Based upon the Standard & Poor fund services, Star Ranking (C10) the performance ranking which is based on an annual basis is shown by star ranking. Taking $SR_{i}$ as the number of stars assigned to investment fund $i$, we can define following objective function for the problem under study. $f_{4}(x)=\sum_{i=1}^{M}SR_{i}x_{i}$ where $SR_{i}$ denotes the number of stars assigned to investment fund $i$. Financial System reporting This means that accounting system is in good such as ERP system (C11) health and organization deals with low risk to do stock trading. ERP financial systems are able to report the status of the company in the right time and at the right amount of information needed for making right decisions. Green Vision of This vision of company indicates that the Company (C12) risks are low and benefits are high.
