Stock C splits two for one in the last period. 02 100 200 200 100 90 50 100 100 200 200 95 45 110 95 45 400 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.
