The TriValue Index is a market value weighted index comprising of three stocks. The number of shares outstanding and the closing stock prices for each of the stocks are given as follows:
Number of shares outstanding Closing price yesterday Closing price today
Stock A 350,000 $23 $23
Stock B 405,000 $43 $41
Stock C 553,000 $56 $58
The number of shares outstanding for the stocks does not change during the period. If the index was closed at 970 yesterday, what is the new index value at market close today?
Price of Stock A yesterday = $23
Number of shares outstanding of Stock A yesterday = 350,000
Market value of Stock A = Price * Number of Shares = 23*350,000 = $8,050,000
Price of Stock B yesterday = $43
Number of shares outstanding of Stock B yesterday = 405,000
Market value of Stock B = Price * Number of Shares = 43*405,000 = $17,415,000
Price of Stock C yesterday = $56
Number of shares outstanding of Stock C yesterday = 553,000
Market value of Stock C = Price * Number of Shares = 56*553,000 = $30,968,000
Market Value of the Index Yesterday = Market value of Stock A + Market value of Stock B + Market value of Stock C
= $8,050,000 + $17,415,000 + $30,968,000 = $56,433,000
Price of Stock A today = $23
Number of shares outstanding of Stock A today = 350,000
Market value of Stock A = Price * Number of Shares = 23*350,000 = $8,050,000
Price of Stock B today = $41
Number of shares outstanding of Stock B today = 405,000
Market value of Stock B = Price * Number of Shares = 41*405,000 = $16,605,000
Price of Stock C today = $58
Number of shares outstanding of Stock C today = 553,000
Market value of Stock C = Price * Number of Shares = 58*553,000 = $32,074,000
Market Value of the Index today = Market value of Stock A + Market value of Stock B + Market value of Stock C
= $8,050,000 + $16,605,000 + $32,074,000 = $56,729,000
Index Value yesterday = 970
Index Value today = Index Value yesterday *(Market Value of the Index today / Market Value of the Index Yesterday)
= 970 *($56,729,000 / $56,433,000) = 970*1.005245158 = 975.09
