Answer: ER(P) = ERX(WX) + ERY(WY)
16 = 13(1-WY) + 9(WY)
16 = 13 - 13WY + 9WY
16 = 13 - 4WY
4WY = 13-16
4WY = -3
WY = -3/4
WY = -0.75
WX = 1 - WY
WX = 1 - (-0.75)
WX = 1 + 0.75
WX = 1.75
The amount to be invested in stock Y = -0.75 x $106,000
= -$79,500
The Beta of the portfolio could be calculated using the formula:
BP = BX(WX) + BY(WY)
BP = 1.14(1.75) + 0.84(-0.75)
BP = 1.995 - 0.63
BP = 1.365
Explanation: The expected return of the portfolio is equal to expected return of stock X multiplied by the weight of stock X plus the expected return of stock Y multiplied by weight of security Y. The weight of security Y is -0.75. The weight of security X is equal to 1 - weight of security Y. Thus, the weight of security X is 1.75 since the weight of security Y is negative. The amount to be invested in security Y is -0.75 x $106,000, which is equal to -$79,500
The Beta of the portfolio equals Beta of stock X multiplied by weight of stock X plus the Beta of stock Y multiplied by weight of stock Y. The weights of the two stocks have been obtained earlier. Therefore, the Beta of the portfolio is 1.365.
Answer:
The maximum investment is $6,360.111
Explanation:
Giving the following information:
The placement of a new surface would reduce the annual maintenance cost to $500 per year for the first 3 years and to $1000 per year for the next 7 years. After 10 years the annual maintenance would again be $2500.
We need to find the net present value. The maximum initial investment will be the amount that makes the NPV cero.
NPV=∑[Cf/(1+i)^n]
Cf= cash flow
<u>For example:</u>
Year 1= 500/1.05= 476.19
Year 3= 500/1.05^3= 431.92
Year 5= 1,000/1.05^5= 783.53
NPV= 6,360.111
The maximum investment is $6,360.111
Answer: B. spillover
Explanation:
A Spillover is used to refer to the effects of an Externality which is what happens when a market exchange leads to effects on a third party that was not party to a transaction between the contracting parties.
The activities that result from the transaction spillover to the third party and can be either negative or positive. A negative spillover would be countries in Africa getting harsher global warming effects due to companies in china polluting the atmosphere.
Answer: No, johnson & johnson should not double its production capacity of their purell hand sanitizer.
Explanation: An increase in demand of hand sanitizers due to the H1N1 flue will shift the demand curve for hand sanitizers to the right. The price of hand sanitizers will increase meaning that greater production levels are profitable. The firms can take advantage of this profitability by increasing manufacturing capacity. However, capacity will be increased for many years and the H1N1 flu is a temporary phenomenon. So, once the H1N1 flu is controlled demand for hand sanitizer is likely to return to previous levels. As a result the increased capacity will then remain idle and unprofitable. So, johnson & johnson should not double its production capacity of their purell hand sanitizer.
Answer:
Option (a) is correct.
Explanation:
Here, shoes are normal goods as there is a positive relationship between the income level of the consumer and the quantity demanded for shoes. It can be seen that as the income of the consumer increases from $19,000 to $21,000 then as a result the quantity of pairs of shoes demanded increases from 9 to 11 pairs. Normal goods are generally have positive income elasticity of demand.
Therefore, the shoes are normal goods in this case.
