The risk-free portfolio that can be formed with the two securities will earn … rate of return

A

11.4%

E(R) = 0.46(13%) + 0.54(10%) = 11.38%

Q

Security M has expected return of 17% and standard deviation of 32%. Security S has expected return of 13% and standard deviation of 19%. If the two securities have a correlation coefficient of 0.78, what is their covariance?

A

0.047

Cov = (0.78)(0.32)(0.19)
