- Calculate the correlation coefficient between Blandy and the market. Use this and the previously calculated (or given) standard deviations of Blandy and the market to estimate Blandy’s beta. Does Blandy contribute more or less risk to a well-diversified portfolio than does the average stock? Use the SML to estimate Blandy’s required return.arrow_forwardTable attached shows the historical returns for Companies A, B and C If one investor has a portfolio consisting of 70% Company A and 30% Company B, what are the average portfolio return and standard deviation? What is Sharpe ratio if the risk-free rate is 3.5%? 2. If another investor has a portfolio consisting of 1/3 Company A, 1/3 Company B and 1/3 Company C, what are the average portfolio return and standard deviation? What is Sharpe ratio if the risk-free rate is 3.5%?arrow_forwardWhich of the following statements is INCORRECT? A stock's beta is calculated as the covariance between the stock's price and the market portfolio return, divided by the variance of the market portfolio return. If we assume that the market portfolio (or the S&P 500) is efficient, then changes in the value of the market portfolio represent systematic shocks to the economy. The risk premium investors can earn by holding the market portfolio is the difference between the market portfolio's expected return and the risk-free interest rate. A stock’s standard deviation is a measure of the total risk.arrow_forward
