Week 1: Portfolio and Risk Management

Q1. A portfolio is equally split between two assets: one half of the wealth is allocated to one asset and the other half of the wealth to the other. Which of the following statements is true?

• The return of the portfolio will be the average of the returns of the
  two individual assets. The risk will be higher than the average of the two individual
  assets provided that their returns are not perfectly correlated.
• The return of the portfolio will be the average of the returns of the
  two individual assets. The risk of the portfolio will be lower than the average
  of the two assets provided that their returns are not perfectly correlated.
• The return of the portfolio will be lower than the average of the
  returns of the two individual assets. The risk will also be lower than the
  average of the two individual assets provided that their returns are not
  perfectly correlated.
• The return of the portfolio will be lower than the average of the
  returns of the two individual assets. Same thing for the risk of the portfolio

Q2. Complete the following sentence:

“An investor should modify his or her Strategic Asset Allocation (SAA) only if…

assets. Which of the following propositions correctly describes these 3 main types of information?

  which measures the risk associated with these returns.
  • The standard deviation of their
    returns, which measures the tendency of their returns.
  • The dependence between the
    returns of the different assets, which measures the correlation between them.

    returns, which measures the risk associated with these returns.
  • The correlation between the
    returns of the different assets, which measures the dependence between them.
  • The tendency of their returns,
    which measures the mean of these returns.

Q1. Asset “A” has an expected return of 6% and a volatility (or standard deviation) of 12%.

• The efficient frontier can be described as the area that contains all the portfolios with the lowest risk for each level of expected return.

• The upper part of the efficient frontier is the one investors should focus on since portfolios on the upper part of the frontier dominate those on the lower part.
• The lower part of the efficient frontier is the one investors should focus on since portfolios on the lower part of the frontier dominate those on the upper part.
• For a given level of expected return, the portfolio that attains this level of expected return with the lowest risk must be on the efficient frontier.

Q3. What happens when we add a risk-free asset to our investable universe?

• We are now able to build a portfolio with zero risk (i.e. certain returns).
• There is no limit to the effect of diversification anymore.
• The upper and lower parts of the efficient frontier are now two straight lines.
• There is one portfolio, the tangency portfolio, which belongs to both efficient frontiers (the one with and the one without the risk-free asset).

• International diversification is beneficial to investors’ portfolios because the returns of foreign assets are typically not perfectly correlated with those of domestic assets, but also between each other.
• Global market integration can reduce the benefits of international diversification.

• Emerging markets’ equity indices generally have a high correlation with developed markets’ equity indices.

Q5. You are building a portfolio for a client. You know that this investor cannot perform short sales. What does it imply?

• The weights (or allocation) to the different assets in this investor’s portfolio cannot be negative.
• The constraint this investor faces is typical for retail investors.
• The fact that the investor cannot perform short sales enhances the possibilities of diversification available to him.

• The investor has to choose between being fully invested in the risk-free asset or fully invested in the Tangency portfolio.
• The investor’s decision boils down to choosing an allocation between only three different portfolios: the risk-free asset, the Tangency portfolio and foreign equities.
• In the risk-return space, the investor will choose a portfolio along the line starting at the risk-free asset and going through the Tangency portfolio.
• The more risk averse he is, the closer his portfolio will be to the risk-free asset.
• In the risk-return space, the investor will choose a portfolio along the line starting at the risk-free asset and going through the Tangency portfolio.
• The Tangency portfolio is the only portfolio on that line that is made up only of risky assets.

Q7. Suppose we are living in an economy with a risk-free asset and many different risky assets. Furthermore, all investors in the economy diversify optimally their portfolio by applying the “Minimum Variance” (or “Mean-Variance”) approach.

Which of the following statements are true?

• The return of any asset in the economy is directly (and linearly) linked to its level of diversifiable risk.
• The market portfolio has a “beta” of 1.
• The Tangency portfolio becomes the market portfolio.
• The “beta” of an asset is a measure of its non-diversifiable risk.

Q8. Suppose asset “A” has a beta of 0.7. The risk-free asset delivers a yearly return of 2%. The yearly expected return of the market portfolio is equal to 8%.

According to the Capital Asset Pricing Model (CAPM), what is the yearly expected return of asset “A”?

Please give your answer in percentage terms and round it to the nearest integer. For example, if your answer is “13.3%”, then type in “13”.

• One of the assumptions of MPT is that the distribution of assets’ returns are leptokurtic.

Week 3: Portfolio and Risk Management

Q1. Which of the following statements regarding the impact of age on the investment profile are true?

• As long as they are employed, investors tend to gradually reduce their allocation to stocks as they get older.
• Because stocks tend to offer attractive risk-adjusted returns over the short run, investors with a short investment horizon are traditionally advised to
  allocate a large portion of their portfolio to stocks.
• When they retire, some investors get completely out of the stock market.
• Because stocks tend to offer attractive risk-adjusted returns over the long
  run, investors with a long investment horizon are traditionally advised to
  allocate a large portion of their portfolio to stocks.

Q2. Which of the following statements regarding the impact of wealth on the investment profile are true?

• Investors’ risk aversion is inversely related to their wealth, meaning that they become more risk averse as they get wealthier.

• Variance and covariance estimates (that are needed for the SAA) are more precise when we use longer datasets.
• Two constraints we traditionally impose on the SAA are that the portfolio weights must be positive (i.e. no leverage is allowed) and that the sum of the portfolio weights must equal 100% (i.e. no short selling is allowed).
• Two constraints we traditionally impose on the SAA are that the portfolio weights must be positive (i.e. no short selling is allowed) and that the sum of the portfolio weights must equal 100% (i.e. no leverage is allowed).

Q7. Which of the following statements regarding Tactical Asset Allocation (TAA) are true?

• TAA has a short to medium term horizon (i.e. from 1 month up to 1 year).
• When a bear market is anticipated, an efficient TAA would reduce the market exposure of the portfolio by moving into risky assets.
• Market timing, valuation and the business cycle are part of the key drivers of TAA.
• TAA involves making permanent modifications to the asset allocation, either across assets or within them.
• Through market timing, TAA seeks to identify over- or under-valued sectors or regions.

Q8. What does it mean if a stock index has a high CAPE (or PE10) with respect to previous years?

• The aggregate earnings of the companies listed in the index have probably decreased a lot over the previous month since the CAPE (or PE10) is very sensitive to recent changes in aggregate earnings.
• One can expect relatively low future returns for this index with respect to its historical returns over the previous years.
• With respect to previous years, the aggregate earnings of the companies listed in the index are relatively low compared to the aggregate price of their shares.
