Assume a utility function of ? = ?[?] − 1 ?? 2. Which statement(s) is/are correct about investors with this utility function? [I] An investor with a higher degree of risk aversion chooses the optimal portfolio with a higher risk premium [II] An investor with a higher degree of risk aversion chooses the optimal portfolio with lower risk [III] An investor with a higher degree of risk aversion chooses the optimal portfolio with a higher sharpe ratio [IV] The extent to which the investor dislikes risk is captured by ? 2 A. [II] only B. [I], [II] only C. [III] , [IV] only D. [II], [IV] only E. [I], [II], [III] only

Consider the following portfolio choice problem. The investor has initial wealth w and utility u(x)=. There is a safe asset (such as a US government bond) that has net real return of zero. There is also a risky asset with a random net return that has only two possible returns, R₁ with probability 1-q and Ro with probability q. We assume R₁ 0. Let A be the amount invested in the risky asset, so that w - A is invested in the safe asset. 1) Does the investor put more or less of his portfolio into the risky asset as his wealth increases?

The following figures show the optimal portfolio choice for two investors with different levels of risk-aversion graphically. Which statement is correct?

please help me check my work and anything unsolved, thanks

Consider a risky portfolio, A, with an expected rate of return of 0.16 and a standard deviation of 0.25, that lies on a given indifference curve. Which one of the following portfolios is not likely to lie on the same indifference curve for a risk-averse investor with a mean- variance utility function? a. Expected return = 0.20; Standard deviation = 0.15 b. Expected return = 0.10; Standard deviation = 0.20 Expected return= 0.15; Standard deviation = 0.20 Expected return = 0.12; Standard deviation = 0.10 Expected return = 0.10; Standard deviation = 0.10 C. d. e.

Give typing answer with explanation and conclusion

Which of the following statements is correct?     A delta-neutral portfolio is protected against large changes in the underlying asset price.     The delta hedging error increases as gamma decreases.     To change the vega of a portfolio, we need to trade the portfolio’s underlying asset.     A delta-neutral portfolio needs to be rebalanced more frequently as the gamma increases to maintain delta-neutrality.   Please explain and justify your choice using your own words.
