Use the end of year price, dividend data $($dividend paid during year$),$ and annual returns provided

below for the common stocks of Norvell and Napier to respond to questions $1$ through $6.$ It is okay

to use your calculator when generating the answers. Just include the equations that you use, and

make sure that you are able to do these calculations on the exam.

Compute the annual returns for $2019$ through $2023($e$.$g$.,$ each year's return$)$ of an equally

weighted portfolio of Norvell stock and Napier stock.

Provide an intuitive explanation of what the correlation coefficient between the returns of the two

securities measures. Comment on whether you would expect the typical correlation coefficient

between two stocks to be positive, negative, or around zero, and why in either case.

Compute the covariance between the returns of Norvell stock and Napier stock.

Now compute the correlation between the Norvell and Napier stocks and indicate how this relates

to the covariance in Question $2.$

You must now compute the standard deviation of the annual returns on the equally weighted

portfolio described in Question $1$ using two different methods.

For Question $5,$ use the actual annual returns of the equally weighted portfolio calculated in

Question $1$ to calculate the portfolio standard deviation.

For Question $6,$ use the equation for the variance of a $2-$asset portfolio that includes the security

weights, the variances of each of the securities$,$ and the covariance between the returns of the two

securities$.$ How does your answer to Question $6$ compare to your answer for Question $5?$
