Problem 11-5 Using the data in the following table, estimate (a) the average return and volatility for each stock, (b) the covariance between the stocks, and (c) the correlation between these two stocks. Complete the steps below using cell references to given data or previous calculations. In some cases, a simple cell reference is all you need. To copy/paste a formula across a row or down a column, an absolute cell reference or a mixed cell reference may be preferred. If a specific Excel function is to be used, the directions will specify the use of that function. Do not type in numerical data into a cell or function. Instead, make a reference to the cell in which the data is found. Make your computations only in the blue cells highlighted below. In all cases, unless otherwise directed, use the earliest appearance of the data in your formulas, usually the Given Data section.

Start Excel - completed. 2. In cell D11, by using cell references and the function AVERAGE, calculate the average return for stock A (1 pt.). 3. In cell E11, by using cell references and the function AVERAGE, calculate the average return for stock B (1 pt.). 4. In cell D12, by using cell references and the function STDEV.S, calculate the volatility of stock A (1 pt.). 5. In cell E12, by using cell references and the function STDEV.S, calculate the volatility of stock B (1 pt.). 6. In cell D13, by using cell references and the function COVARIANCE.S, calculate the covariance of stock A and stock B (1 pt.). 7. In cell D14, by using cell references and the function CORREL, calculate the correlation of stock A and stock B (1 pt.) 8. Save the workbook. Close the workbook and then exit Excel.
