Using the data from the chart below, calculate the first-period rates of return on the following indexes of the three stocks:

Assume the equally-weighted index at time 0=100.

Calculate the geometric equally-weighted index at t=1.

Calculate the rate of return based on these two index numbers.

	P(0)	Q(0)	P(1)	Q(1)	P(2)	Q(2)
A	90	100	95	100	95	100
B	50	200	45	200	45	200
C	100	200	110	200	55	400
