Consider the three stocks in the following table. P_trepresents price at time t, and Q_trepresents shares outstanding at time t. There are three time points 0, 1, and 2.

	P0	Q0	P1	Q1	P2	Q2
A	90	100	95	100	100	100
B	50	200	45	200	45	200
C	100	200	110	200	105	200

a) Form an equally weighted portfolio in stocks A, B, C at time 0 and hold it to time 1.

Calculate the portfolio return from 0 to 1.

Keep two decimal places.

b) Form an equally weighted portfolio in stocks B, C (No Stock A) at time 1 and hold it to time 2.

Calculate the portfolio return from 1 to 2.
