Suppose you are currently invested 100% in U.S. stocks and you CANNOT short: a.Find the portfolio that maximizes expected return

Volgvan

Answer:

Part a: The portfolio which maximizes the expected return is in the attached file.

Part b:The portfolio's expected rate of return is 11.20% and the weight is 100% for US only.

Explanation:

As the question is incomplete and the data is not available, thus the complete question is found as attached with the solution.

The Sharpe rate is given as

$S_a=\frac{E_a-E_r}{\sigma}$

Where

E_a is the estimated rate of return for a value
E_r is the risk free rate of return
σ is the standard deviation of the investment.

The portfolio variance is given as

$\sigma^2_{portfolio}=\sum_{i}^{n}{\sigma_i^2w_i^2}+\sum_{i}^{n(n-1)/2}{cv_i}$

Where

σ is the standard deviation of the investment.
w is the weighted value of the investment
cv is the covariance term

Portfolio standard deviation is given as

$\sigma_{portfolio}=\sqrt{\sigma^2_{portfolio}}$

Expected rate is given as

$E_{rate of return}=\sum_{i=1}^{n}{E_a_i\times w_i}$

Now the Sharp value is calculated as above.

Now the values as given in the excel sheet are added in the attached excel sheet, following formulas are used to calculate various values

Sharpe ratio is calculated using =(B6-J3)/C6

Portfolio variance is calculated using (=B13^2*C6^2+B14^2*C7^2+B15^2*C8^2+B16^2*C9^2+2*B13*B14*C6*C7*D7+2*B13*B15*C6*C8*D8+2*B13*B16*C6*C9*D9+2*B14*B15*C7*C8*E8+2*B14*B16*C7*C9*E9+2*B15*B16*C8*C9*F9)

Portfolio standard deviation is SQRT(Variance)

Expected return is calculated using =B13*B6+B14*B7+B15*B8+B16*B9

Sharpe is calculated using =(B23-$J$3)/B22

Part a:

The portfolio which maximizes the expected return is in the attached file.

Part b:

The portfolio's expected rate of return is 11.20% and the weight is 100% for US only.

If the prices of X and Y are $2 and $4 per unit, respectively, and this consumer has $10 in income to spend, to maximize total u

DaniilM [7]

Answer: 1 unit of X and 2 units of Y

Explanation: Total utility is the complete satisfaction you get from maximising usage of a quantity of a good or service. However another element also needs to be considered, and that is marginal utility. Marginal utility is the satisfaction you get from consuming an additional quantity of a good or service.

Both these factors are important as they determine how much of each product the consumer should buy. To maximise total utility, the consumer must use the full $10 income. But the question still stands as to which combination of products should the consumer purchase.

To make it fair the consumer should start by purchasing one of X and one of Y, and keep taking one of each (starting with X) to keep it fair. However after taking one of X, worth $2, and one of Y, worth $4, there is only $4 left. That means that if the consumer then takes one of X there will be $2 left, disallowing the consumer to afford X, and thus making the purchases unfair. Therefore in terms of meeting the marginal utlility, it is better to then swop to purchasing Y with the remaining $4, and maximising the consumer's total utility.

The theory of purchasing power parity A.assumes that most changes in nominal exchange rates are the result of changes in real ex

Neko [114]

Answer:

The correct answer is letter "B": extends the law of one price to a group of goods.

Explanation:

Purchasing Power Parity or PPP compares different country's currencies through a market basket of goods approach. Two currencies are in PPP when a market basket of goods, taking into account the exchange rate, is priced the same in both countries.

The Law of one price states that individual and identical goods or services will have the same price if there were no friction between global markets. Thus, the PPP approach would be the extent of the law of one price adding the exchange rates.
