Summary Introduction
To compute:TheReward-to-volatility (Sharpe) Ratio of risky portfolio and the client’s risky portfolio.
Introduction:
Reward-to-volatility(Sharpe) Ratio of risky portfolio: An investor has to calculate the returns he would get by investing. So, the execution of the funds Sharpe or Reward- Volatility ratio is used. It reveals exact details about the fund to the investor and also suggests that higher ratio reflects higher returns for every unit of risk taken.

Consider an economy with a (net) risk-free return r1 = 0:1 and a market portfolio with normally distributed return, with ErM = 0:2 and 2M = 0:02. Suppose investor A has CARA preferences, with risk aversion coe¢ cient equal to 1 and an endowment of 10.
a) Write down the maximization problem for the investor.
b) Determine the amount invested in the risky portfolio and in the risk-free asset.
c) Suppose another investor (B) has a coe¢ cient of absolute risk aversion equal to 2 (and the same endowment 10). Compute his optimal portfolio and compare it to that of investor A. Explain the di§erent results for investors A and B.
d) Finally, consider Investor C with mean-variance preferences Ec V ar(c) (and endowment 10). Compute his optimal portfolio and compare it to that of investors A and B (as obtained in questions b and c). Compare your result with those obtained for investors A and B.
Consider the multifactor model APT with three factors. Portfolio A has a beta of 0.8 on factor 1, a beta of 1.1 on factor 2, and a beta of 1.25 on factor 3. The risk premiums on the factor 1, factor 2, and factor 3 are 3%, 5%, and 2%, respectively. The risk-free rate of return is 3%. The expected return on portfolio A is __________ if no arbitrage opportunities exist.
A. 23.0%
B. 16.5%
C. 13.4%
D. 13.5%
As a portfolio manager, assume the following information: The beta of your portfolio 1.2 Your performance is exactly on target with the SML data under condition 1 Assume the true SML data is given under condition 2. Condition 1 RFR Rm(proxy) Condition 2 0.04 0.1 0.05 0.12 Rm(true) How much does your performance differ from the true SML?
