摘要：Ever since the dollars started flowing as a result of the sale of petroleum,the Middle East region has been faced the dilemma of where to invest such funds. Investors wanted to deposit their funds in investments in line with Shari’ah rules. The western banking system responded swiftly and efficiently to tap into this lucrative and expansive market,by offering equity funds that are deemed to be socially responsible. The downside of this investment strategy is that most of these funds have a concentration risk. One way how to reduce this risk is to include sukuk bonds. It has been demonstrated that after introducing such securities modern portfolio theory indicates that the risk return profile is pushed closer to the efficient frontier. This outcome is a favorable occurrence that all investors would gladly acknowledge.
