Question

1)A stock has an expected return of 16.2 percent, a beta of 1.75, and the expected return on the market is 11% what must the risk-free rate be?

 

2) Base on the following information; calculate the expected return and standard deviation of each of the stocks. Assume each state of the economy is equally likely to happen. What are the covariance and correlation between the returns of the two stocks?


State of Economy     Return on stock A            Return on Stock B
Bear                              .082                                            -.065

Normal                        .095                                             .124

Bull                              .063                                         .185

Explanation / Answer

1.Expected Return Stock A = 7.9% Stock B = 8.1%

2.Standard deviation Stock A = 0 Stock B = 1.1%

Since standard deviation of stock A = 0 then covariance and correlation
coefficient between the returns of stock A and stock B are zero.
