Consider the three stocks in the following table. Prepresents price at time t, and Qt represents shares outstanding at time t Stock C splits two for one in the last period. 110 100 200 20 115 230 230 Pi 115 95 205 01 115 230 230 P2 115 95 110 02 115 230 460 C Calculate the first-period rates of return on the following indexes of the three stocks (t = 0 to t= 1): (Do not round intermediate calculations. Round your answers to 2 decimal places.) a. A market-value-weighted index. Rate of return % b. An equally weighted index. Rate of return %
