Question 3

While portfolio A has a return of 15% with a standard deviation of 40%, the market portfolio has a 10% return and 10% standard deviation. Given a 5% annual risk-free rate, what is the resulting return for this M² hypothetical portfolio?

Accepted Answer

The M² measure adjusts the portfolio's return to the market's risk level. The formula is: M² = Rf + (Rp - Rf) * (σm / σp). Substituting the given values: M² = 5% + (15% - 5%) * (10% / 40%) = 7.5%.

Question 4

Suppose that portfolio Y has a 20% return and 22% standard deviation. Market portfolio has a 15% return and 15% standard deviation. The annual risk-free rate is 5%. What is the M² measure?

Accepted Answer

The M² measure refers to the Sharpe Ratio, which is calculated as follows: Sharpe Ratio = (Portfolio Return - Risk-Free Rate) / Portfolio Standard Deviation For portfolio Y: Sharpe Ratio = (20% - 5%) / 22% = 0.6818 For the market portfolio: Sharpe Ratio = (15% - 5%) / 15% = 0.6667 Therefore, the M² measure for portfolio Y is higher than that of the market portfolio, indicating that portfolio Y has a better risk-adjusted return. The only choice that matches this calculation is C, 0.23%.

Question 5

What is the smallest expected loss with a probability of 2.5 percent over the next two months for a portfolio with an annual expected return of 13 percent and a standard deviation of 28 percent?

Accepted Answer

The smallest expected loss at a 2.5% probability is calculated using the Value at Risk (VaR) formula. For a normal distribution, VaR can be calculated as: VaR = Z * σ * √(t/12) - μ * (t/12), where Z is the Z-score for 2.5% (approximately -1.96), σ is the annual standard deviation, μ is the annual expected return, and t is the time period in months. Plugging in the values, we get: VaR = -1.96 * 0.28 * √(2/12) - 0.13 * (2/12) = -20.24%.

Question 6

While portfolio Z has a return of 15% with a standard deviation of 40%, the market portfolio has a 10% return and 10% standard deviation. Given a 5% annual risk-free rate, what is the percentage of portfolio Z will be included in the M² hypothetical portfolio?

Accepted Answer

The percentage of portfolio Z included in the hypothetical portfolio can be determined using the Sharpe ratio. The Sharpe ratio is calculated as (Return of Portfolio - Risk-Free Rate) / Standard Deviation of Portfolio. The portfolio with the highest Sharpe ratio is more desirable. However, in this context, the question seems to be asking about the construction of an optimal portfolio combining the market portfolio and portfolio Z, possibly hinting at the Capital Allocation Line (CAL) where portfolios are mixed to achieve a desired risk-return profile. Without specific formulas or additional context provided in the question, such as the exact method to calculate the percentage (e.g., through the use of the Capital Market Line or another specific model), the answer cannot be directly calculated from the information given. However, given the choices provided and assuming the question implies a calculation based on the Sharpe ratio or a similar concept, the answer provided seems to be an estimation or requires additional information not provided in the question. Therefore, the correct response based on standard financial theories and the information given would typically be "Undetermined," but since the explanation is based on the assumption of missing calculation details or context, the chosen answer "E" suggests there might be a specific context or formula assumed in the question that is not explicitly stated.

Question 8

High Mountain Homes has an expected annual return of 16.1 percent and a standard deviation of 22.3 percent. What is the smallest expected loss over the next month given a probability of 2.5 percent?

Accepted Answer

Using the formula for expected loss, EL = (z-score)(standard deviation), where the z-score corresponding to a 2.5 percent probability is -1.96. 
EL = (-1.96)(22.3%) = -43.708%. 
However, since the question asks for the smallest expected loss, we need to find the closest value to -43.708% that is greater than the expected return of 16.1%. 
This means we need to find the smallest expected loss greater than -27.608%. 
We can use the formula E(R) + EL = E(R) - z*(standard deviation) to solve for the required return, which gives E(R) + EL = 16.1% - (-1.96)*(22.3%) = -11.28%. 
Therefore, the smallest expected loss with a probability of 2.5% is -11.28%, which is answer choice C.
