Portfolio B, expected return 9%, standard deviation 26%

Which of the following portfolios most likely falls below the efficient frontier? Portfolio A, expected return 7%, standard deviation 14% Portfolio B, expected return 9%, standard deviation 26% Portfolio C, expected return 12%, standard deviation 22%

If the correlation coefficient were 0, a zero-variance portfolio could be constructed

Which of the following statements about correlation is least likely correct? Potential benefits from diversification arise when correlation is less than 1 If the correlation coefficient were 0, a zero-variance portfolio could be constructed The lower the correlation coefficient, the greater the potential benefits from diversification

Portfolio invested in the stock 84.06% Portfolio invested in the bond 15.94% Expected return 15.57% Standard deviation 32.31%

A pension fund manager is considering three mutual funds. The first is a stock fund, the second is a long-term government and corporate bond fund, and the third is a T-bill money market fund that yields a rate of 4.7%. The probability distribution of the risky funds is as follows: Fund; Expected Return; Standard Deviation Stock fund (S); 17%; 37% Bond fund (B); 8; 31 The correlation between the fund returns is 0.17. Solve numerically for the proportions of each asset and for the expected return and standard deviation of the optimal risky portfolio.

A pension fund manager is considering three mutual funds. The first is a stock fund, the second is a long-term government and corporate bond fund, and the third is a T-bill money market fund that yields a sure rate of 4.2%. The probability distributions of the risky funds are: Fund; Expected Return; Standard Deviation Stock fund (S); 12%; 33% Bond fund (B); 5%; 26% The correlation between the fund returns is .0308. What is the reward-to-volatility ratio of the best feasible CAL?

a. Standard deviation 20.56% b-1. Proportion invested in the T-bill fund 11.92% b-2. Proportion Invested Stocks 56.95% Bonds 31.13%

A pension fund manager is considering three mutual funds. The first is a stock fund, the second is a long-term government and corporate bond fund, and the third is a T-bill money market fund that yields a sure rate of 5.5%. The probability distributions of the risky funds are: Fund; Expected Return; Standard Deviation Stock fund (S); 15%; 32% Bond fund (B); 9%; 23% The correlation between the fund returns is 0.15. Suppose now that your portfolio must yield an expected return of 12% and be efficient, that is, on the best feasible CAL. a. What is the standard deviation of your portfolio? b-1. What is the proportion invested in the T-bill fund? b-2. What is the proportion invested in each of the two risky funds?

A portfolio is composed of two stocks, A and B. Stock A has a standard deviation of return of 16%, while stock B has a standard deviation of return of 22%. Stock A comprises 60% of the portfolio, while stock B comprises 40% of the portfolio. If the variance of return on the portfolio is .031, the correlation coefficient between the returns on A and B is _________.

A portfolio was created by investing 25% of the fund in assets A (standard deviation = 15%) and the rest of the funds in assets B (standard deviation = 10%). If the correlation coefficient is 0.75, what is the portfolio's standard deviation?
