Your supervisor gave you the price information for each stock collected from Yahoo! Finance in an excel file. (you can see the file attached here.) 1. Convert these prices to monthly returns as the percentage change in the monthly prices. For this, create a separate worksheet within the Excel file. Note that to compute a return for each month, you need a beginning and ending price, so you will not be able to compute the return for the first month. 2. Compute the mean monthly returns and standard deviations for the monthly returns of each of the stocks. Convert the monthly statistics to annual statistics for easier interpretation (multiply the mean monthly return by 12 , and multiply the monthly standard deviation by 12 ).
