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

0.047424

Explanation:

Given that

Expected return of security M = 17%

Standard deviation of Security M = 32%

Expected return of security S = 13%

Standard deviation of security S = 19%

And, the correlation coefficient = 0.78

So, by considering the above information the co variance is

= Correlation coefficient * Standard deviation of Security M * Standard deviation of security S

= 0.78 * 0.32 * 0.19

= 0.047424
