what do the risk-free rate and the optimal risky portfolio
create?
They create a portfolio with the maximum utility that lies on the efficient Frontier.
1. Modern portfolio theory assumes that investors are
rational.
2. They want to maximize the utility of their portfolio.
3. According to modern portfolio theory utility is a positive
function of return and negative function of risk.
4. To calculate portfolio with maximum utility, we calculate the
coefficient of variation.
5. Coefficient of variation is standard deviation divided by the
return of the portfolio.
6. Lower the coefficient of variation, the better, the lower the
unit of risk per unit of return.
7. The portfolio with a lower coefficient of variation in the pool
of portfolio- lies on efficient Frontier.
8. So a portfolio on efficient Frontier gives the lowest amount of
risk per unit of return.
9. That's why we invest in the portfolio on efficient Frontier
rather than portfolio below the Efficient Frontier (inefficient
portfolio/all other possible portfolios).
We want to invest in such a way due to utility maximization approach.

Under MPT (Modern Portfolio Theory), what do the risk-free rate and the optimal risky portfolio create and why is it important relative to all other possible portfolios (with the exception of the optimal risky portfolio)?
The risk-free rate is 5%. A risky portfolio has an expected return of 10% and a standard deviation of return of 20%. If you want to form a complete portfolio from these two assets, and you want this portfolio to have an expected return greater than 5% but less than 10% what must you do? Assume that all borrowing and lending can be done at the risk-free rate. a. Lend at the risk free rate b. borrow at the risk...
An investor's risk aversion determines her a. optimal mix of assets in her risky portfolio b. risk-free rate on borrowing c. Sharpe ratio d. capital allocation line e. optimal risky portfolio f. risk-free rate on lending
Find the weights for the optimal risky portfolio. Assuming risk-free rate is 3%. E(rs) =10% E(rB )= 5% σs = 15% σB = 6% PBS = 0.3
Harry Markowitz' 1952 dissertation, 'Portfolio Selection' revolutionized modern finance creating MPT (modern portfolio theory). As useful as Markowitz' paradigm of mean-variance optimization is, what are shortcomings of the methodology in practice? Mean-variance optimization assumes that prior returns of assets are indicative of their future returns. Mean-variance optimization assume that the prior correlations between assets will hold into the future (for example, that A and B's correlation estimated over the prior period will hold into the next period). Mean-variance optimization assumes...
Suppose that the rate of return on risky assets is given by the following single factor model: where F is the factor affecting returns on all securities and e, is a firm-specific dis- turbance. The risk-free rate is 4% and borrowing at this rate is possible. Two well- diversified portfolios P and Q are found to have the following expected returns and betas: E(rp) 12% ßP : 0.8 (a) Explain why these data are inconsistent with Arbitrage Pricing Theory (b)...
Suppose the optimal risky portfolio has an expected return of 13.25% and a standard deviation of 24.57%. Mr. Jones wants an efficient portfolio with an expected return of 12%. If the optimal risky portfolio consists of 70.75% in stocks and 29.25% in bonds, what is the proportion of Mr. Jones' portfolio invested in the stock fund. the risk-free rate is 5.5%.
Under CAPM, more risk-averse individuals hold a portfolio of risky assets that is tilted toward stocks with low covariance risk relative to the portfolio of risky assets held by less risk-averse individuals. II. III. True False Uncertain Why? 7
Given an optimal risky portfolio with an expected return of 0.09, standard deviation of 0.17, and a risk-free rate of 0.03, what is the slope of the best feasible capital allocation line (CAL)?
A. Capital Allocation Lines The optimal CAL is found as the ray from the risk free rate that is tangent to the _____________ and is called the ________________. efficient frontier; CML minimum variance portfolio; high range CAL indifference curve; SML lower half of the investment opportunity set; CAPM B. Capital Allocation Portfolio 1 has a standard deviation of 35% and a Sharpe ratio of 0.48. Portfolio 2 has a standard deviation of 29% and a Sharpe ratio of 0.44. Portfolio...
