In the CAPM world, two securities, A and B, are priced efficiently, i.e., they fall on the SML. The expected return of A is 20%, and its beta is 1.6. The expected return of B is 11%, and its beta is 0.7. The expected return of the market portfolio is ___and the risk free rate is ___.

	A.	15% and 6%
	B.	15% and 5%
	C.	14% and 4%
	D.	16% and 6%
	E.	18% and 6%

Expert Solution

Ans C. 14% and 4%

Stock A
Expected Return =	Risk free Return + (Market Risk Premium)* Beta
20% =	Risk free Return + (Market Risk Premium)* 1.60	(a)

Stock B
Expected Return =	Risk free Return + (Market Risk Premium)* Beta
11% =	Risk free Return + (Market Risk Premium)* 0.7	(b)


Solving Equation (a) and (b)

20% =	Rf+ (Market Risk Premium)* 1.60
11% =	Rf + (Market Risk Premium)* 0.70


9% =	(1.60-0.70)* (Market Risk Premium)
Market Risk Premium =	9% / 0.90
	10.00%


From (a)
20% =	Rf+ (Market Risk Premium)* 1.6
20% =	Rf + 10% * 1.6
Rf =	20% - 16%
Rf =	4.00%

Risk Free Rate =	4.00%

Market Return =	Market Risk Premium 6 Risk Free Rate
Market Return =	10% + 4%
Market Return =	14%


Expected Return =	Risk free Return + (Market Return - Risk free return)* Beta
	4% + (14% - 4%) * 1
	14.00%

CAPM can trace its development from Portfolio Theory (i.e. the two fund separation theorem) which shows that the process of optimizing the return/risk ratio will ensure that every investor will invest in a portfolio of risk free asset and the risky market portfolio (also known as the two fund separation theorem). Explain and illustrate why no one will invest in other risky portfolios other than the market portfolio. What is the special property of this market portfolio? (Hint: a graph...

Consider two perfectly positively correlated risky securities, A and B

Consider two perfectly positively correlated risky securities, A and B. Security A has an expected rate of return of 16% and a standard deviation of return of 20%. B has an expected rate of return of 10% and a standard deviation of return of 30%. Solve for the minimum variance portfolio (i.e., what are the weights in A and B of the minimum variance portfolio). What is the variance of this portfolio?

For this question, think of the world as having two goods—movies and “all other goods,” i.e. a composite good. Your good friend Jane really likes to go to the movies and she goes quite often. You think movies are alright, but you aren’t as enamored/obsessed with them as Jane is and hence you go far less than she does. Show explain that despite these differences, at the margin, you and Jane value an addition movie at the same rate relative...
