Question 2: Consider three stocks in the following table. Prepsents price at time t, and Qt represents shars outstanding at time t. Qo P1 P. A $ 150.00 B$ 65.00 C$ 200.00 100 200 400 $ 160.00 $ 60.00 $ 214.00 Q1 100 200 400 a. Calculate the rate of return on the price weighted index of the three stocks from t=0 to t=1. (3 points) Index Value at time (0) = Index Value at time (1) = 138.3333333 91.33333333 Rate of return = =(C12-C11)-1 b. If stock C has a two-for-one stock split at t=1, what should be the new divisor at end of period t = 1? (3 points) Index Value piror to stock split = Index Value after stock split = New divisor = ? ? ? Question 1: A municipal bond has a yield of 5%.
