Part 2

1.) Two securities have the following characteristics:

E(R_a)=.06    σ_a = .04
E(R_b)=.08    σ_b = .10

1A) Fill in the missing cells (A through O) in the table. For each of two correlation cases, corr. = -1 and corr. = 0, calculate the attainable portfolios' mean and standard deviation from combining the two assets together using weights in increments of 25% from 1 to 0. Also, calculate the minimum risk portfolio's weights, mean and standard deviation for the correlation= 0 case (for the case of the correlation = -1, I have already calculated the weights for you!). Assume that the risk free rate is .04. Hint: in some of the cases, filling in the cells requires no calculations. Note, throughout this problem, returns are in decimal form, i.e., 1%=0.01.

		Corr = 0			Corr = -1
Weight in A	Weight in B	E(Rp)	σp	E(Rp)		σp
1.0	0.0	0.06	E)	H)		M)
0.75	0.25	A)	0.03905	I)		0.005
0.50	0.50	0.07	0.05385	J)		N)
0.25	0.75	0.075	F)	K)		0.065
0.0	1.0	B)	0.10	L)		0.10
Minimum risk portfolio for corr=0
C)	D)	0.06275	G)	NA		NA
Minimum risk portfolio for corr=-1
0.7143	0.2857	NA	NA	0.0657		O)

1B) Consider the data in part A for the case of the correlation = 0. Below is the formula for the weight in asset A in the tangency portfolio (that is, the tangency portfolio that is found from extending a line from the risk-free rate to the tangency point of the attainable portfolios curve):

W_A = [E(R_A) - r_f]σ²_b - [E(R_b) - r_f]σ_aσ_bcorr(R_a,R_b)/ [E(R_A) - r_f]σ²_b + [E(R_b) - r_f]σ_a² - [E(R_a) - r_f + E(R_b) - r_f]σ_aσ_bcorr(R_a,R_b)

E(Ra)=.06  σ_a = .04
E(Rb)=.08 σ_b = .10

For the tangency portfolio, find the weight in asset A and B, the portfolio mean, and the standard deviation. Assume that the risk free rate is .04.

1C) Find the reward-to-variability ratio (the slope) of the tangency line (i.e., the capital allocation line).

1D) You want to invest in a portfolio along the capital allocation line that will earn an expected return of 0.11. What will be the portfolio's standard deviation?

2. Assume that security returns are generated by the single index model

R_i = α_i + β_iR_M + ε_i

where R_i is the excess return for security and R_M is the market's excess return. Suppose also that there are three securities A, B, and C characterized by the following data:

Security	Beta	Expected Return	σ2(εi)
A	0.8	0.10	0.05
B	1.0	0.12	0.01
C	1.2	0.14	0.10

A.) If σ²_M =0.04 calculate the variance (e.g. the total risk) of returns of securities A, B, and C.

B.) Now assume there are an infinite number of assets with the return characteristics identical to those of A, B, and C, respectively. If one forms a well-diversified portfolio of type A securities, what will be the variance of the portfolio's return? Similarly, what will the variance of the portfolio's return for portfolios formed only from type B? type C?

C) Listed below are the characteristic lines and correlation's (correlation of each fund with the market) for three mutual funds:

R₁ =-0.5 + 1.25Rm p=0.8

R₂ =1.25 + 0.95Rm p=0.75

R₃ =0.75 + 1.35Rm p=0.7

Which fund has the most non-diversifiable risk?

D) What percent of each fund's risk is systematic and non-systematic?

3) Consider two assets, A and B. The correlation of returns between asset A and B is zero. Starting with the formula for the variance of a portfolio composed of the two assets, derive an expression for the weight placed in asset A and the weight placed in asset B for the minimum risk portfolio. Firm A is a factory that makes models of tiny factories, and firm B is a factory that makes models of factories that make models of tiny factories.
