LOS t: Explain alpha and beta separation as an approach to active management and demonstrate the use of portable alpha. ffice ffice" />
Q1. Which of the following is least accurate regarding an alpha and beta separation approach?
A) This approach may obscure investment risks.
B) The alpha position is more costly than the beta position.
C) A portable alpha strategy means that an investor can easily pick up systematic risk through a variety of positions.
Correct answer is A)
One of the advantages of an alpha and beta separation approach is that the investor can better understand and manage the risks in an alpha and beta separation approach because they are more clearly defined. The investor also has a better idea of the costs of investing. The passive beta exposure is typically cheaper than the active alpha exposure. In a portable alpha strategy, the investor can easily pick up systematic risk through a variety of positions using equity index positions while maintaining the long-short alpha.
Q2. Which of the following would least likely be a component of an alpha and beta separation approach for an investor who is restricted from explicit long-short investing strategies?
A) A long position in a large-cap equity futures contract.
B) A short position in a small-cap equity futures contract.
C) A market neutral hedge fund.
Correct answer is C)
A market-neutral hedge fund strategy would be undertaking long-short positions so this would not be available to the investor. An investor restricted from long-short strategies could create a similar exposure as the alpha and beta separation approach by taking a long position in a large-cap index futures contract and invest with a small-cap manager to generate the alpha. To become market neutral in the small-cap market, the investor would then short a futures contract based on small-cap equities.
Q3. Which of the following is least likely to be a limitation of an alpha and beta separation approach?
A) The investor may be exposed to systematic risk.
B) It may be difficult to implement in markets.
C) Some long-short strategies may have a degree of systematic risk.
Correct answer is A)
One of the main reasons to undertake an alpha and beta separation approach is to gain an exposure to systematic risk (the beta) through a long position in an equity index. The alpha is picked up using a long-short approach.
