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%
<span>The basic economic problem will affect Bill Gates who is one of the the world's wealthiest people because scarcity of resources is more so related to goods and services, and not how much money one may have. While he may be able to buy all the goods and services he wants as many as he wants for a unlimited amount time, he could only have access to those things if they are available.</span>
The above answer is definitely correct in its details. I'd just like to emphasize a couple of important ideas about Hoover's response.
<span>He tried to do more to fix the economy than any president had ever done before. The government had been very hands-off up to that point.He believed the government should not go in debt no matter what. This limited what he was willing to do. Please note that economists back then agreed with this idea so it's not like Hoover was just being mean. In fact, FDR believed the same thing and it's often said that he undermined the New Deal by trying to balance the budget too soon.</span>
So, overall what I want to point out is that Hoover did more than anyone else, and he did what most economists of the time would have said was the right thing to do. But it didn't work and so he's seen as one of the worst presidents ever, which seems a bit unfair.
