Question

Security X has expected return of 9% and standard deviation of 18%. Security Y has expected return of 12% and standard deviation of 21%. If the two securities have a correlation coefficient of -0.4, what is their covariance

Answer 1

Answer:

the covariance is -0.0151

Explanation:

The computation of the covariance is given below:

= correlation coefficient × standard deviation of x × standard deviation of y

= -0.4 × 18% × 21%

= -0.0151

Hence, the covariance is -0.0151

We simply applied the above formula so that the correct value could come
