### Week 3

#### Quiz 1: Utility and risk aversion

Q1. One way to measure investors’ risk aversion is by comparing their certainty equivalent. Economists define the certainty equivalent return rCE of a risky portfolio as the sure return that an investor would be wiling to accept instead of the risky portfolio. If you are more risk averse, what do you expect your rCE to be smaller or larger?

- If the investor is more risk averse, rCE will be larger
**If the investor is more risk averse, rCE will be smaller**- The value of rCE will be indifferent of how risk averse the investor is.
- The value of rCE will be equal to zero and indifferent of how risk averse the investor is.

Q2. Suppose that we have the following utility function. What can you conclude about this investor’s attitude towards risk based on her utility function?

- A risk neutral investor
**A risk-loving investor**- A risk averse investor
- None of the above

Q3. Which of the following statements are correct? (Select all that apply.)

**Most individuals have risk aversion levels between 1 and 10.****The concavity of the utility function measures the degree of risk aversion.****The level of risk aversion is different for each individual.**- Utility functions typically decrease with wealth.

Q4. Which of the following statements is true about a risk-neutral investor?

**A risk-neutral investor considers only the expected return in judging a risky portfolio.**- For a risk-neutral investor, the certainty equivalent is greater than the expected rate of return on a risky prospect.
- A risk-neutral investor is characterized by an infinite risk aversion coefficient.
- A risk-neutral investor penalizes the expected rate of return from a risky portfolio to account for the risk involved.

Q5. The concavity of the utility function implies that going from $1 to $2 is more valuable for investors than going from $100,000 to $100,001.

**True**- False

#### Quiz 2: Portfolio choice with mean-variance preferences

Q1. Consider the following three investment options:

Which investment would you choose if your preferences are represented by mean-variance utility and your risk aversion coefficient is equal to 3?

Q2. Suppose you have the following utility function.

You have an investment opportunity that will give you a future wealth of either

$4,000 or $6,000 with equal probability. Which of the following statements is

correct?

- For a certain wealth of $5,000, the utility you

will get will be equal to 2.23. - For a certain wealth of $5,000, the utility you

will get will be lower than 2.23. **For a certain wealth of $5,000, the utility you**

will get will be higher than 2.23.- For a certain wealth of $5,000, the utility you

will get will be higher than 2.50.

Q3. Compare S&P 500 and volatility strategies (Ang (2014)):

Below is a graph that compares the cumulative wealth obtained from

investing $1 in March 1989 from two strategies: investing in the S&P

500 equity index and volatility strategy. Volatility strategy is an

investment strategy that earns premiums during stables times (essentially

equivalent to selling volatility insurance), but has large losses during

volatile times such as the financial crisis of 2008-09.

Which one of the following is a limitation of using mean-variance preferences in comparing these two strategies?

**It does not account for tail events.**- It does not account for risk aversion.
- It takes into account only expected returns of each strategy
- It takes into account only the volatility of each strategy

Q4. Consider the three following investment opportunities:

Which investment would you choose if your preferences are represented by mean-variance utility function and you are risk-neutral?

- Investment A
- Investment B
**Investment C**

Q5. Which of the following statements is correct?

- In the mean-variance space, the indifference curve of a less risk-averse investor will be steeper compared to that of a more risk-averse investor.
**Indifference curves are graphical representations of choices or combinations that give individuals the same level of utility.**- Moving northwest in mean-variance space, indifference curves are associated with lower levels of utility
- The risk aversion of an investor is irrelevant to indifference curves.

Q6. Your financial advisor offers you a portfolio of equities with an expected return of 20% and standard deviation of 30%. Suppose at the time of this offer, U.S. Treasuries offer a safe return of 5%. Suppose your preferences can be described by mean-variance preferences, and you know your risk aversion parameter A to be equal to 2. Which would you prefer?

**Equities**- U.S. Treasuries

Q7. Suppose you have two investment opportunities: A gives you a future wealth of either $150,000 or $50,000 with equal probability. B gives you a future wealth of 125,000 with probability 2/3 and 55,000 with probability of 1/3. Suppose, also, that your preferences can be described by a log utility function. In other words, U(W)=ln(W). If you are maximizing your expected utility, which investment would you choose?

- Investment A
**Investment B**

Q8. Maximizing utility in mean-variance space graphically corresponds to

- Choosing the steepest indifference curve you can attain
- Choosing the flattest indifference curve you can attain
**Choosing the highest indifference curve moving northwest**- Choosing the lowest indifference curve moving southeast

#### Quiz 3: Mean-variance preferences

Q1. True or False.

A fair game is a risky prospect that has a zero risk premium. It will not be undertaken by a risk-neutral investor.

- True
- False

Q2. Which of the following statements is false?

- Indifference curves in mean-variance space show the risk and return combinations that give us the same level of utility.
- The degree of risk aversion of an investor characterizes the slope of the indifference curve.
- More risk-averse investors have less steep indifference curves.

- Investment A
- Investment B
- Investment C

Q4. Which of the following is/are true about mean-variance preferences? (Select all that apply.)

- The utility score of a risky portfolio can be interpreted as the certainty equivalent rate of return.
- The certainty equivalent rate is the maximum rate that a risky portfolio would need to provide.
- The certainty equivalent rate is the minimum rate that a risky portfolio would have to provide.

#### Week 4

#### Quiz 1: Mean-variance optimization

Q1. Which of these is not correct about the Capital Allocation Line (CAL)?

**The slope of the CAL is called reward to return ratio.**- The CAL provides us with all the possible combinations of the optimal risky portfolio with the risk-free asset.

- The CAL goes from the risk-free rate and through the optimal risky portfolio.

Q2. Which of the following statements is not true?

- Other things equal, investors would prefer a steeper-sloping CAL.
- The optimal capital allocation in the risky portfolio for an investor is proportional to the risk premium.
**Sharpe ratio is the ratio of the return of the risky asset to the return of the risk-free asset.**- The solution to the optimal capital allocation decision for an investor is found graphically by finding the tangency portfolio between the investor’s indifference curve and the CAL.

portfolio of risky assets with an expected return of 10% and volatility of

17%. The risk-free asset has a return of 1.5%. What is the Sharpe ratio of

is 5%, what would your capital allocation between these two assets have to

be?

- Invest 43.3% in the index fund and 56.67% in Treasuries
**Borrow 20% of your wealth and invest 120% of your wealth in the index fund**- Invest 20% in Treasuries and 80% in the index fund
- Invest 100% of your wealth in the index fund
