6.3 Coca-Cola's (ticker symbol = KO) December ending prices (adjusted for stock splits and dividends) and its annual dividend are given below. This information can be obtained from a source such as Yahool Finance. Place these data in a spreadsheet for columns A through C. Use three decimal places and calculate results in decimal form (n percentages). You will need the 2000 price to calculate the 2001 return. For each year 2001-2010: a. Calculate as column D the return relative for the price change only. b. Calculate as column E the return based on price change only. c. Calculate as column F the return relative based on total return (price change and dividends). d. Calculate as column G the return based on total return (price change and dividends). e. Calculate the arithmetic and geometric means for 2001-2010 for price change only and for total return. f. Calculate the endingwwealth as of December 31,2010 , for $1 invested in Coca-Cola stock at the beginning of 2001. g. Calculate the standard deviation of the returns for the years 2001-2010. (Note: Use the total returns and not the return relatives.)
