You are given the following information concerning four stocks: Stock A B C D Shares outstanding 1,000 300 2,000 400 Price 20X0 50 30 20 60 20X1 50 30 40 60 20X2 50 60 20 60 Using 20X0 as the base year, construct three aggregate measures of the market that simulate the Dow Jones Industrial Average, the S & P 500 stock index, and the Value Line stock index (i.e., a simple average, a value-weighted average, and a geometric average). a) What is the percentage change in each aggregate market measure form 20X0 to 20X1, and 20X0 to 20X2?
