In most important business decisions, there are two key financial considerations: risk and retum. As an investor, an individual needs to expand his/her consideration towards the performance of individual assets as compared to just concentrating on the return behavior of a few large portfolios. Firstly, the person should know the risk of individual assets and how to measure them. Secondly, the person must quantify the relationship between an asset's risk and its required return. An investor named Sumayyah is considering investing in three (3) different stocks or creating three distinct two-stock portfolios. Sumayyah considers herself to be a rather conservative investor. She is able to obtain forecasted returns for the three securities for the years 2021 through 2027. The data of the individual stocks are given in the following table. Year 2021 2022 2023 2024 2025 2026 2027 STOCK X 10% 12% 14% 13% 15% 13% 11% STOCK Y 10% 12% 9% 13% 11% 16% 16% STOCK Z 12% 13% 9% 10% 8% 8% 9% In any possible two-stock portfolio, the weight of each stock in the portfolio will be 50%. The three possible portfolio combinations are XY, XZ, and YZ. As an investment advisor, your task is to recommend the appropriate investment strategies that are most suited to your client's investment portfolio, in this case, Sumayyah. You are required to: 1. Determine the expected return and risk of: a. individual stocks. b. three possible portfolio combinations. 2. Give your recommendation to Sumayyah whether she should invest in: a single stock X or the portfolio consisting of stock X and Y. b. single stock Y or the portfolio consisting of stock Y and Z. Your recommendation must be from the risk-retur viewpoint
