Consider the three stocks in the following table. P represents price at time t, and Qt represents shares outstanding at time t. Stock C splits two-for-one in the last period. (LO 2-2) Q0 P1 Q1 P2 A 90 100 95 100 95 100 B 50 200 45 200 45 200 100 200 110 200 55 400 a. Calculate the rate of return on a price-weighted index of the three stocks for the first period (t = 0 to t= 1). b. What must happen to the divisor for the price-weighted index in year 2? c. Calculate the rate of return of the price-weighted index for the second period (t = 1 to t= 2)
