Consider the three stocks in the following table. Pt represents price at time t, and t represents shares outstanding at time L. Stock C splits two-for-one in the last period. Required: a. Calculate the rate of return on a price-weighted index of the three stocks for the first period ( t=0 to t=1). (Do not round intermediate colculations. Round your answer to 2 decimal places.) b. What will be the divisor for the price-weighted index in year 2? (Do not round intermediate calculations, Round your answer to 2 decimal places.) c. Calculate the rate of return of the price-weighted index for the second period ( t=1 to t=2)
