Assume that security returns are generated by the singleindex model,
Ri alpha i beta iRM ei
where Ri is the excess return for security i and RM is the markets excess return. The riskfree rate is Suppose also that there are three securities A B and C characterized by the following data:
Security beta i Erisigma ei
A
B
C
a If sigma M calculate the variance of returns of securities A B and CDo not round intermediate calculations. Round your answers to the nearest whole number.
Variance
Security A
Security B
Security C
b Now assume that there are an infinite number of assets with return characteristics identical to those of A B and C respectively. If one forms a welldiversified portfolio of type A securities what will be the mean and variance of the portfolios excess returns? What about portfolios composed only of type B or C stocks? Enter the variance answers as a percent squared and mean as a percentage. Do not round intermediate calculations. Round your answers to the nearest whole number.
