Excel Activity: Evaluating Risk and Return Start with the partial model in the file ChO2 P15 Build a Model.x/sx. The file contains data for this problem. Goodman Corporation's and Landry Incorporated's stock prices and dividends, along with the Market Index, are shown here. Stock prices are reported for December 31 of each year, and dividends reflect those paid during the year. The market data are adjusted to include dividends. The data has been collected in the Microsoft Excel file below. Download the spreadsheet and perform the required analysis to answer the questions below. Do not round intermediate calculations. Use a minus sign to enter negative values, if any. Downlead spreadsheet Ch02 P15 Build a Model-10e311.xisx a. Use the data given to calculate annual returns for Goodman, Landry, and the Market Index, and then calculate average annual returns for the two stocks and the index. (Hint: Remember, returns are calculated by subtracting the beginning price from the ending price to get the capital gain or loss, adding the dividend to the capital gain or loss, and then dividing the result by the beginning price. Assume that dividends are already included in the index. Also, you cannot calculate the rate of return for 2016 because you do not have 2015 Calculate the standard deviations of the returns for Goodman, Landry, and the Market Index. (Hint: Use the sample standard deviation formula, which corresponds to the STDEV.S function in Excel.) Round your answers to two decimal places. . Construct a scatter diagram graph that shows Goodman's returns on the vertical axis and the Market Index's returns on the horizontal axis. Construct a similar graph showing Landry's stock returns on the vertical axis. Choose the correct graph. The correct graph is A Stocks' Returns vs. Index's Returns aluating Risk and Return
