Suppose that there are many stocks in the security market and that the characteristics of stocks A and B are given as follows: S
Tomtit [17]

Answer:

0.135 or 13.5%

Explanation:

Given in the question are the following:

ERA = Expected return of Stock A = 12% = 0.12

ERB = Expected return of Stock B = 19% = 0.19

SDA = Standard deviation of Stock A = 3% = 0.03

SDB = Standard deviation of Stock B = 9% = 0.09

CAB = Correlation between A and B = -1

The correlation of -1 between Stock A and Stock B indicates that there a perfect negative correlation between the two stocks. Therefore, we can create a risk-free portfolio which its rate of return will be the risk-free rate in equilibrium.  

If we let wA denotes the proportion of investment in Stock A, and let wB denotes the proportion of investment in Stock B, the proportion of this portfolio can be obtained by setting its standard deviation equal to zero. Since there is a perfect negative correlation, the standard deviation of this portfolio (SDP) can be given as follows:

Absolute value [(wA × SDA) – (wB × SDB)] = SDP …………………………………….. (1)

Note that wB = (1 – wA) since the sum of the weight must be equal to 1.

Substituting all the relevant values into equation and set SDP = 0, we have  

[(0.03 × wA) − (0.11 × (1 - wA))] = 0

0.03wA – 0.11 + 0.11wA = 0

0.03wA + 0.11wA = 0.11

0.14wA = 0.11

wA = 0.11 ÷ 0.14 = 0.785714285714286

Since wB = 1 –wA, therefore:

wB = 1 - 0.785714285714286 = 0.214285714285714

The expected rate of return of the portfolio (ERP) can be estimated as follows:

ERP = (wA × ERA) + (wB × ERB)  ................................. (2)

Substituting all the relevant values into equation (2), we have:

ERP = (0.785714285714286 × 0.12) + (0.214285714285714 × 0.19)  

       = 0.0942857142857143 + 0.0407142857142857

ERP = 0.135 or 13.5%

Therefore, the value of the risk-free rate must be 13.5%.

At which price and quantity combination would the government regulate this firm to get as close as possible to the most efficien
Kipish [7]

Answer:

Point C and G. Refer to the attached image.

Explanation:

According to the attached image, the price and quantity combination the government would regulate this firm to get as close as possible to the most efficient point for society is C and G because, this is the point where marginal cost MC and Average Total Cost intercept and form lower equilibrium point.

This means that if company sell at this point they will not run at shortage and also for buying society, the quantity they will buy is also at the increase making it the most efficient point for the society.

stiks02 [169]

Answer:

They came back home at 12 pm

Explanation:

Giving the following information:

The Burkes pay their babysitter​ $5 per hour before 11 P.M. and​ $7.50 after 11 P.M. One evening they went out for 4 hr and paid the sitter ​$27.50.

We need to formulate the total cost:

TC= 5*x + 7.5*y

x=5*4= 20

y=7.5*1= 7.5

TC= 5*4 + 7.5*1= $27.5

They came back home at 12 pm

During 2021, Sysco Corp. had 950,000 shares of common stock and 100,000 shares of 7% preferred stock outstanding. The preferred
solong [7]

Answer:

c. $6.03

Explanation:

<u>Earnings available to common shareholders</u>

Net Income                                                             $6,000,000

Less: Preference dividend                                     <u>$200,000   </u>

Net Income available to common shareholders  <u>$5,800,000</u>

<u />

Number of Common shares = 950,000

Equivalent common shares for convertible 5% Bonds = 10,450. [Number of bonds = 2,100,000/1,000 = 2,100 shares. Equivalent common shares = 2,100 * 5 = 10,500 shares]

Weighted average number of common shares outstanding = 950,000 + 10,500 = 960,500

Earnings per share = Earnings available to common shareholders / Weighted average number of common shares outstanding

Earnings per share = $5,800,000 / 960,500

Earnings per share = 6.038521603331598

Earnings per share = $6.04
