The question is incomplete. Here is the complete question:
The following annual returns for Stock E are projected over the next year for three possible states of the economy. What is the stock’s expected return and standard deviation of returns? E(R) = 8.5% ; σ = 22.70%; mean = $7.50; standard deviation = $2.50
State Prob E(R)
Boom 10% 40%
Normal 60% 20%
Recession
30% - 25%
Answer:
The expected return of the stock E(R) is 8.5%.
The standard deviation of the returns is 22.7%
Explanation:
<u>Expected return</u>
The expected return of the stock can be calculated by multiplying the stock's expected return E(R) in each state of economy by the probability of that state.
The expected return E(R) = (0.4 * 0.1) + (0.2 * 0.6) + (-0.25 * 0.3)
The expected return E(R) = 0.04 + 0.12 -0.075 = 0.085 or 8.5%
<u>Standard Deviation of returns</u>
The standard deviation is a measure of total risk. It measures the volatility of the stock's expected return. The standard deviation (SD) of a stock's return can be calculated by using the following formula:
SD = √(rA - E(R))² * (pA) + (rB - E(R))² * (pB) + ... + (rN - E(R))² * (pN)
Where,
- rA, rB to rN is the return under event A, B to N.
- pA, pB to pN is the probability of these events to occur
- E(R) is the expected return of the stock
Here, the events are the state of economy.
So, SD = √(0.4 - 0.085)² * (0.1) + (0.2 - 0.085)² * (0.6) + (-0.25 - 0.085)² * (0.3)
SD = 0.22699 or 22.699% rounded off to 22.70%
The correct answers to these open questions are the following.
Maple Farms, Inc. v. City School District of Elmira.
Could something like this bankrupt a company?
Yes, it can, if the proper forecast were not done taking into consideration all of the possible variables at medium and long-range.
Do you agree with the decision?
It was a tough decision because the court declared in its decision that the performance was not impracticable, as Maple Farm Inc indicated when decided to break the contract.
In strict theory, I agree with the court's decision because the explanation was that an "impractical" occurred when an event happened totally unexpected. And in this case, Mapple Farm Inc could have taken extra provisions knowing that milk had a 10% increase the last year and had the chance of more increases in the present year.
That is how a company can avoid this type of situation. Taking better provisions, contemplating all kinds of variables, knowing that in the future, something unexpected can happen and could be prevented with the proper forecast.
Answer:
When Economists say that humans make decisions at the margin they mean that decisions are made on the basis of the cost and benefit of getting an additional unit of a good/ service.
Marginal benefit refers to the additional utility that we will derive from consuming one extra unit of a good or service and factors in heavily into our decision making. We usually accept a decision if the Marginal benefit is higher or equal to the Marginal cost ( cost of the additional unit) of the good/service.
If the Marginal Cost is instead higher, the decision would most probably be cancelled.
Answer:
This question is incomplete, the options are missing. The options are the following:
A) The old price times the change in quantity.
B) The old price times the new quantity.
C) The new price times the change in quantity.
D) The old quantity times the change in price.
And the correct answer is the option D: The old quantity times the change in price.
Explanation:
To begin with, the name of <em>"Price Effect"</em> refers to a concept known in economics as the situation where a consumer is affected by the change in the price that a good he plans to buy staying everything else constant. This effect is quantifiable as the old quantity times the change in price when we see the representation in a graphic due to the fact that when the demand curve moves the new position will be established by that new price that have affected the consumer given the same old quantity.
Answer: 12400
Explanation:
It should be noted that 50% of the stick value will be paid by the customer and also 100% of the mutual fund shares value will also be paid because they are nonmarginable securities.
Therefore, 50% of $12,000 = $6,000
Total payment required will now be:
= $6,000 + $2,400 + $4,000
= $12,400.
