(5). The variance of Stock A is .005, the variance of the market is .008 and the covariance between the two is .0026. What is the correlation coefficient

0.4110

Explanation:

The formula and computation of the correlation coefficient is shown below:

Correlation co-efficient = Covariance ÷ (Standard deviation of market × Standard deviation of Stock A)

where,

Covariance between the two = 0.0026

Variance of the stock A = 0.005

And, the variance of the market is 0.008

Now placing these values to the above formula

So, the correlation coefficient is

= 0.0026 ÷ (0.008 × 0.005)^0.50

= 0.0026 ÷ 0.006324555

= 0.411096096

= 0.4110

Hence, the correlation coefficient is 0.4110
