Yousif believes that each asset's risk can be assessed in two ways: in isolation and as part of the firm's diversified portfolio of assets. The risk of the assets in isolation can be found by using the standard deviation and coefficient of variation of returns over the past 10 years. The capital asset pricing model (CAPM) can be used to assess the asset's risk as part of the firm's portfolio of assets. Applying some sophisticated quantitative techniques, Yousif estimated betas for assets X and Y of 1.60 and 1.10, respectively. Also, he found that the risk-free rate is currently 7% and that the market return is 10%
