Concept explainers
1. Currently, the risk-free return is 3 percent and the expected market rate of return is 10 percent. What is the expected return of the following three-stock portfolio?
2. The market and Stock S have the following probability distributions:
a. Calculate the expected rates of return for the market and Stock S.
b. Calculate the standard deviations for the market and Stock S.
c. Calculate the coefficients of variation for the market and Stock S.
Formula to calculate expected return using the CAPM is given by:
Expected return = Rf + beta(Rm - Rf)
where Rf is the risk free rate & Rm is the market rate of return
Formula to calculate portfolio beta is:
Amount invested/total amount*individual betas
Expected rate of return for the market & stock is given by:
Expected return = R1P1 + R2P2......RnPn
Step by stepSolved in 2 steps
- Consider two types of assets: market portfolio (M) and stock A. The expected return is 8% and standard deviation of the market portfolio is 15%. The risk-free rate is 2%. The standard deviation of market portfolio returns is 15%. The standard deviation of stock A is 30%, and the beta coefficient is 1. Draw the capital market line and show the position of stock A.arrow_forwardConsider the following securities: state Probability A B A B H M L 0.2 0.5 0.3 с 6 10 6 3 7 12 2 5 14 1. The expected payoff of A is: 2. The standard deviation of A is: 3. If the price of A is 3, its expected return is: 4. The covariance between A and B is: 5. The correlation coefficient between A and B is: 6. Is it possible to build a portfolio that has zero variance using A and C? YES/ NOarrow_forwardAssume that the risk-free rate, RF, is currently 9% and that the market return, rm, is currently 16%. a. Calculate the market risk premium. b. Given the previous data, calculate the required return on asset A having a beta of 0.4 and asset B having a beta of 1.8.arrow_forward
- Explain well all question with proper answer. And type the answer step by step.arrow_forwardA stock has a market beta of 0.86 and a standard deviation of 0.28. If the market standard deviation is 0.30, what is the covariance between the stock return and the market return?arrow_forwardAn investment has probabilities 0.15, 0.34, 0.44, 0.67, 0.2 and 0.15 of giving returns equal to 50%, 39%, -4%, 20%, -25%, and 42%. What are the expected returns and the standard deviations of returns?arrow_forward
