- Draw the indifference curve in the expected return–standard deviation plane corresponding to a utility level of .05 for an investor with a risk aversion coefficient of 3. (Hint: Choose several possible standard deviations, ranging from 0 to .25, and find the expected rates of return providing a utility level of .05. Then plot the expected return–standard deviation points so derived.)arrow_forwardCompute the (1) net present value, (2) profitability index, and (3) internal rate of return for each option. (Hint: To solve for internal rate of return, experiment with alternative discount rates to arrive at a net present value of zero.) (If the net present value is negative, use either a negative sign preceding the number eg -45 or parentheses eg (45). Round answers for present value and IRR to 0 decimal places, e.g. 125 and round profitability index to 2 decimal places, e.g. 12.50. For calculation purposes, use 5 decimal places as displayed in the factor table provided.)

- An investor wants to follow a spread strategy by buying a put for 6$ with a strike price of 95$ and writing a put for 4$ with a strike price of 90$. a. Draw the graph of strategy payoffs and profits b. Find the equilibrium price of this strategy (the equilibrium price is the market price of the stock where the profit is 0) c. What is the maximum profit and loss from this strategy?arrow_forwardSuppose the nominal rate of return is 0.085 and the risk-free rate is 0.010. What is the risk premium? Instruction: Round to two decimal places. E.g., if your answer is 0.0106465 or 1.06465%, you should type ONLY the number .01, neither 0.0106465, 0.0106, nor 1.065. Otherwise, Blackboard will treat it as a wrong answer.arrow_forwarda. What is the market risk premium (M-FRF)? Round your answer to two decimal places. % b. What is the beta of Fund P?

- Which one of the following statements is correct? Multiple Choice The risk-free rate of return has a risk premium of 1.0. The reward for bearing risk is called the standard deviation. Risks and expected return are inversely related. The higher the expected rate of return, the wider the distribution of returns. Risk premiums are inversely related to the standard deviation of returns.arrow_forwardAssume the standard deviation of the market return is 0.2, the standard deviation of asset k is 0.45 and the beta of asset k is 0.675. The correlation coefficient between the return from asset k and the return from the market is: A. 0.473 OB. 0.900 OC. No answer OD. 0.290arrow_forwardSuppose you want to establish a bullish spread strategy. The are two call options. The first one has X1=$50 and C1=$5. The second one has X2=$42 and C2=$6. When the underlying asset price is S(t)=$45, what is the profit from the strategy? What is the maximum profit of the strategy? What is the minimum payoff of the strategy?arrow_forward
- Three decision makers have assessed utilities for the following decision problem (payoff in dollars): The indifference probabilities are as follows: Plot the utility function for money for each decision maker. Classify each decision maker as a risk avoider, a risk taker, or risk-neutral. For the payoff of 20, what is the premium that the risk avoider will pay to avoid risk? What is the premium that the risk taker will pay to have the opportunity of the high payoff?arrow_forwarda) Discuss the difference between a price-weighted index and a value-weighted index. Give one example for the price-weighted index and one example for the value-weighted index and discuss any problems/advantages associated with the specific indices. b) We assume that investors use mean-variance utility: U = E(r) – 0.5 × Ao², where E(r) is the expected return, A is the risk aversion coefficient and o? is the variance of returns. Given that the optimal proportion of the risky asset in the complete port- folio is given by the equation y* = E , where r; is the risk-free rate, E(rp) is the expected returm of the risky portfolio, o, is variance of returns, and A is the risk aversion coefficient. For each of the variables on the right side of the equation, discuss the impact of the variable's effect on y* and why the nature of the relationship makes sense intuitively. Assume the investor is risk averse. Aoarrow_forwardAlternatives A C D E alternatives have the following returns and standard deviations of returns.
