Mr Henry can invest in Highbull stock and Slowbear stock.
His projection of the returns on these two stocks is as follows:
State of Probability of Return on Return on
Economy State Occurring Highbull Stock (%) Slowbear Stock (%)
Recession 0.25 - 2.00 5.00
Normal 0.60 9.20 6.20
Boom 0.15 15.40 7.40
a. Calculate the expected return on each stock.
b. Calculate the standard deviation returns on each stock.
c. Calculate the covariance and correlation between the returns on the
1.2 Solve Problems 10.6 on page 289, RWJ Chapter 10
Suppose the expected returns and standard deviations of stocks A and B are E(RA) = 0.15, E(RB) = 0.25, A 0.1 and B = 0.2 respectively.
a. Calculate the expected returns and standard deviations of a portfolio that is composed of 40 percent A and 60 percent B when the correlation between the returns on A and B is 0.5.
b. Calculate the standard deviation of portfolio that is comprised of 40 percent A and 60 percent B when the correlation coefficient between the returns on A and B is -0.5.
c. How does the correlation between the returns on A and B affect the standard deviation of the portfolio?

Suppose you observe the following situation:
Return if State Occurs
State of Economy Probability of State Stock A Stock B
Bust 0.25 -0.1 -0.3
Normal 0.5 0.1 0.05
Boom 0.25 0.2 0.4
1.4 Solve Problems 10.38 on page 293, RWJ Chapter 10
Suppose you have invested $30,000 in the following Stocks:
Security Amount Invested Beta
Stock A $ 5,000 0.75
Stock B 10,000 1.1
Stock C 8,000 1.36
Stock D 7,000 1.88
The risk-free rate is 4 percent and the expected return on the market portfolio is 15 percent. Based on the capital asset pricing model, what is the expected return on the above portfolio?
