You are hired to make investment decisions for a large pension fund. You meet with representatives from the company to figure out what kind of choices to make. To get things started you try to figure out their risk preferences. You discuss the concept of risk and return with them to figure out what their level of risk aversion is. You ask them if they would rather invest in the portfolio that offers an expected rate of return of 10% and a standard deviation of 15% or in the short term money market which offers a risk-free 5% rate of return. They say that they prefer the risky portfolio.
STEP BY STEP SHOW:
A) What is the maximum level of risk aversion for which the risky portfolio is still preferred to the risk-free investment? What can you now say about the company’s employee’s risk preferences? Hint: the easiest way to think about this is to find the level of risk aversion A for which an investor is indifferent between two investments
Now, you ask them: if a risky portfolio had an 18% standard deviation, at what rate of return would they prefer it to a risk-free investment that offers 5%? They say the expected return would need to be at least 10%. They say that at that rate they would be exactly indifferent between the two investments
B) What can you determine about their risk preferences? You decide to invest in the risky portfolio because your analysis suggests that the expected return is equal to 11%. Now news comes to the market that makes you revise your estimate of the portfolio’s standard deviation to 2-%.
You can not reach the representative by phone
C) Should you change the pension fund investments to a risk-free investment which still offers 5%?
