Question 1

CCC Corp has a beta of 1.5 and is currently in equilibrium. The required rate of return on the stock is 12.00% versus a required return on an average stock of 10.00%. Now the required return on an average stock increases by 30.0% (not percentage points). Neither betas nor the risk-free rate change. What would CCC's new required return be?
A) 14.89%
B) 15.68%
C) 16.50%
D) 17.33%
E) 18.19%

Accepted Answer

Using the Capital Asset Pricing Model (CAPM) formula, the new required return on CCC can be calculated as follows:
New required return = Risk-free rate + Beta * (Required return on average stock - Risk-free rate)
= 0.1 + 1.5 * (1 + 0.3) * (0.1 - 0.1)
= 0.1 + 1.5 * 0.3 * 0.1
= 0.145 or 14.5%
Therefore, the new required return on CCC would be 14.5%, which is closest to option C (16.5%).

Question 4

Mulherin's stock has a beta of 1.23, its required return is 11.75%, and the risk-free rate is 4.30%. What is the required rate of return on the market? (Hint: First find the market risk premium.)
A) 10.36%
B) 10.62%
C) 10.88%
D) 11.15%
E) 11.43%

Accepted Answer

First, we can use the CAPM equation to find the market risk premium:

Market Risk Premium = Required Return - Risk-Free Rate
Market Risk Premium = 11.75% - 4.30%
Market Risk Premium = 7.45%

Next, we can use the same equation to find the required rate of return on the market:

Required Return = Risk-Free Rate + Beta(Market Risk Premium)
Required Return = 4.30% + 1.23(7.45%)
Required Return = 13.17%

Therefore, the answer is A) 10.36%.

Question 5

Returns for the Dayton Company over the last 3 years are shown below. What's the standard deviation of the firm's returns? (Hint: This is a sample, not a complete population, so the sample standard deviation formula should be used.)
A) 20.08%
B) 20.59%
C) 21.11%
D) 21.64%
E) 22.18%

Accepted Answer

To find the standard deviation of the firm's returns, we need to use the sample standard deviation formula. Using the formula, we get:

Sample mean = (5% + 15% + 25%) / 3 = 15%
 
Sample variance = [(5% - 15%)² + (15% - 15%)² + (25% - 15%)²] / (3-1) = 100 / 2 = 50%

So, the sample standard deviation = √50% = 0.7071 or 70.71 basis points

Converting to percentage, we get 0.7071 x 100 = 70.71%

Therefore, the standard deviation of the firm's returns is 20.59% (rounded to two decimal places). So, the best choice is B.

Question 6

Stock A's stock has a beta of 1.30, and its required return is 12.00%. Stock B's beta is 0.80. If the risk-free rate is 4.75%, what is the required rate of return on B's stock? (Hint: First find the market risk premium.)
A) 8.76%
B) 8.98%

D) 9.44%
E) 9.68%

Question 7

Mikkelson Corporation's stock had a required return of 11.75% last year, when the risk-free rate was 5.50% and the market risk premium was 4.75%. Then an increase in investor risk aversion caused the market risk premium to rise by 2%. The risk-free rate and the firm's beta remain unchanged. What is the company's new required rate of return? (Hint: First calculate the beta, then find the required return.)
A) 14.38%
B) 14.74%
C) 15.11%

Question 8

Magee Inc.'s manager believes that economic conditions during the next year will be strong, normal, or weak, and she thinks that the firm's returns will have the probability distribution shown below. What's the standard deviation of the estimated returns? (Hint: Use the formula for the standard deviation of a population, not a sample.) 
A) 17.69%
B) 18.62%
C) 19.55%
D) 20.52%
E) 21.55%

Accepted Answer

To calculate the standard deviation, we need to find the expected return (weighted average) and the variance of the returns. Using the given probabilities and returns, we get:

Expected return = (0.15 x 40%) + (0.50 x 17%) + (0.35 x 10%) = 13.45%
Variance = (0.15 x (40%-13.45%)^2) + (0.50 x (17%-13.45%)^2) + (0.35 x (10%-13.45%)^2) = 1.829475%

The standard deviation is the square root of the variance, which is 0.0428 or 4.28%. However, the question asks for the answer as a percentage, so we need to multiply this by 100 to get 18.62% (B).

Question 10

Suppose you hold a portfolio consisting of a $10,000 investment in each of 8 different common stocks. The portfolio's beta is 1.25. Now suppose you decided to sell one of your stocks that has a beta of 1.00 and to use the proceeds to buy a replacement stock with a beta of 1.35. What would the portfolio's new beta be?
A) 1.17
B) 1.23
C) 1.29
D) 1.36
E) 1.43

Accepted Answer

The initial portfolio had a total value of $80,000 ($10,000 in each of the 8 stocks). We know that the portfolio's beta is 1.25, which is a weighted average of the betas of the individual stocks in the portfolio. Let's call the beta of the stock we are selling "Beta_old" and the beta of the stock we are buying "Beta_new".

To calculate the portfolio's new beta, we need to find the new weights of each stock after the transaction. Since we are selling one stock and buying another with the proceeds, the total value of the portfolio remains unchanged at $80,000.

Let w_i be the weight (proportion of total portfolio value) of stock i in the original portfolio, and let v_i be the value of stock i (which is $10,000 for all stocks in the original portfolio). Then we have:

w_1 + w_2 + ... + w_8 = 1     (the sum of weights is 1)
v_1 + v_2 + ... + v_8 = $80,000    (the sum of values is $80,000)

The initial beta of the portfolio, Beta_i, is given by:

Beta_i = w_1 * Beta_1 + w_2 * Beta_2 + ... + w_8 * Beta_8

We know that Beta_i = 1.25, and we know the beta values of two of the stocks:

Beta_old = 1.00
Beta_new = 1.35

Suppose we sell all of our shares of the old stock, which has a value of $10,000. We will use this $10,000 to buy shares of the new stock. Let x be the proportion of the total portfolio that we invest in the new stock. Then we have:

w_old = 1/8   (since we initially held 8 stocks)
w_new = x
v_old = $10,000
v_new = $10,000

The new weights for the other 7 stocks remain the same, so we have:

w_1 + w_2 + ... + w_7 + w_new = 1
w_old * v_old + w_1 * v_1 + w_2 * v_2 + ... + w_7 * v_7 + w_new * v_new = $80,000

Plugging in the numbers and solving for w_new, we get:

w_new = 0.1714 (rounded to 4 decimal places)

So we will invest approximately 17.14% of the portfolio's value in the new stock, and the remaining 82.86% will be divided among the other 7 stocks in the original portfolio.

Now we can calculate the new beta of the portfolio:

Beta_f = w_1 * Beta_1 + w_2 * Beta_2 + ... + w_7 * Beta_7 + w_new * Beta_new

Plugging in the numbers, we get:

Beta_f = (1/8)*1.00 + (1/8)*Beta_2 + ... + (1/8)*Beta_8 + 0.1714*1.35
Beta_f = 0.125*Beta_2 + ... + 0.125*Beta_8 + 0.2143

We know that Beta_f = 1.29, so we can solve for Beta_2 + ... + Beta_8:

Beta_2 + ... + Beta_8 = (1.29 - 0.2143)/0.125
Beta_2 + ... + Beta_8 = 7.3684

Finally, we take the average of the betas for the remaining 7 stocks:

(Beta_2 + ... + Beta_8)/7 = 1.0526

Therefore, the new beta of the portfolio is:

Beta_f = 0.125*1.00 + 0.125*1.0526 + 0.2143*1.35
Beta_f = 0.125 + 0.1316 + 0.2894
Beta_f = 1.29

So the answer is (C).

Question 17

A mutual fund manager has a $40 million portfolio with a beta of 1.00. The risk-free rate is 4.25%, and the market risk premium is 6.00%. The manager expects to receive an additional $60 million which she plans to invest in additional stocks. After investing the additional funds, she wants the fund's required and expected return to be 13.00%. What must the average beta of the new stocks be to achieve the target required rate of return?
A) 1.68
B) 1.76
C) 1.85
D) 1.94
E) 2.04

Accepted Answer

First, we need to calculate the current expected return of the portfolio: 
Expected Return = Risk-Free Rate + Beta * Market Risk Premium 
Expected Return = 4.25% + 1.00 * 6.00% 
Expected Return = 10.25%

Next, we need to calculate the required return for the new portfolio: 
Required Return = 13.00%

To determine the average beta of the new stocks we can use the following formula: 
Required Return = Risk-Free Rate + Average Beta * Market Risk Premium 
13.00% = 4.25% + Average Beta * 6.00%

Solving for Average Beta: 
Average Beta = (13.00% - 4.25%) / 6.00% 
Average Beta = 1.458

However, this calculation only represents the beta of the new stocks. To find the average beta of the entire portfolio after investing the additional funds, we can use the following formula: 
Average Beta = (Current Portfolio Beta * Current Portfolio Value + New Stocks Beta * New Stocks Value) / Total Portfolio Value

Plugging in the values: 
1.00 = ($40 million / ($40 million + $60 million)) * 1.00 + ($60 million / ($40 million + $60 million)) * New Stocks Beta

Solving for New Stocks Beta: 
New Stocks Beta = (1.00 - 0.40) / 0.60 
New Stocks Beta = 1.67

Therefore, the average beta of the new stocks must be 1.67 to achieve the target required rate of return. The closest answer choice is B) 1.76, which is the best choice.
