AIM 1: Explain and distinguish between the strategies followed by “Capital Decimation Partners” and “Capital Multiplication Partners.”

1、The Capital Decimation Partners hypothetical strategy is most similar to which of the following?

A) Buying insurance.

B) Selling insurance.

C) A perfect market-timing strategy.

D) A protective put option strategy.


作者: wanganjie    时间: 2009-7-2 11:22

 

The correct answer is B

Capital Decimation Partners, CDP, strategy of writing out-of-the money puts is most similar to selling insurance. A perfect market-timing strategy is consistent with the CMP strategy. The CMP strategy is a protective put strategy that involves a long position a put option on the underlying asset, and the underlying asset (S& 500), which is the same as buying insurance.

2、The Capital Multiplication Partners hypothetical strategy is least similar to which of the following:

A) Buying insurance.

B) Selling insurance.

C) A perfect market-timing strategy.

D) A dynamic asset allocation strategy.


作者: wanganjie    时间: 2009-7-2 11:22

 

The correct answer is B

Capital Multiplication Partners, CMP, is a hypothetical perfect market strategy that is also a dynamic asset-allocation strategy. The CMP strategy has been proven to be the same as holding a long position in the S& 500 and a put option on the S& 500 with the strike price equal to the Treasury bill rate. Buying a put when owning the underlying asset is equivalent to buying insurance. The CDP strategy of writing out-of-the money puts is the most similar with selling insurance.

4、Which of the following best describes the Capital Multiplication Partners strategy?

A) Writing out-of-the-money puts.

B) A covered call strategy.

作者: wanganjie    时间: 2009-7-2 11:23

 

The correct answer is C

A perfect market-timing strategy is consistent with the CMP strategy. The CMP strategy is a protective put strategy that involves a long position, a put option on the underlying asset, and the underlying asset (S& 500), which is the same as buying insurance.

AIM 2: Compare the relative performance of various hedge fund strategies.

1、The Sharpe ratio for hedge funds is overstated:

A) if the standard deviation of the hedge fund is overstated.

B) during periods when the risk-free rate is low.

C) if the hedge fund is liquid.

D) if a hedge fund returns have high positive serial correlation.


作者: wanganjie    时间: 2009-7-2 11:23

 

The correct answer is D

High values of positive autocorrelation is an indication of illiquidity exposure, which would create low values for the standard deviation and therefore overstate the Sharpe ratio.

A) Risk factor.

B) Sharpe Ratio.

C) A linear clone.

D) Risk premium.
作者: wanganjie    时间: 2009-7-2 11:25

A) Managed Futures.

B) Event Driven.

C) Emerging Markets.

D) Fixed Income Arbitrage.


作者: wanganjie    时间: 2009-7-2 12:47

 

The correct answer is A

The results indicate that the Managed Futures and Global Macro linear clones out perform the actual fund for both the fixed-weight and rolling-window construction.



作者: wanganjie    时间: 2009-7-2 12:47

 

AIM 5: Distinguish between “fixed-weight” and “rolling-window clones,” explain their construction and compare the differences between these strategies.

1、Linear clones of hedge fund categories using a five-factor model:

A) have higher values for the first-order auto correlation than the hedge funds they replicate.

B) outperform the all hedge funds categories they attempt to replicate.

C) cannot be actively traded.

D) have more liquidity than the hedge funds they replicate.


作者: wanganjie    时间: 2009-7-2 12:47

 

The correct answer is D

All of the linear clones have low values for autocorrelations, confirming that the clones are more liquid.



作者: wanganjie    时间: 2009-7-2 12:48

 

2、Which of the following best describes the impact of leverage on the linear clones that replicate hedge fund styles?

I.           Linear clones are not practical because the leverage values were too high to be practical.

II.         Linear clones can replicate the returns of hedge funds they represent by using futures contracts.

III.        The high amounts of leverage required to replicate the hedge fund returns makes the linear clones not practical.

A) I only.

B) III only.

C) II only.

D) I and III.


作者: wanganjie    时间: 2009-7-2 12:48

 

The correct answer is C

The impact of leverage is evaluated by using a renormalization factor. An analysis of the values for the renormalization factors indicates that leverage can be replicated using futures contracts. Therefore, the implied leverage in the clones is practical.


作者: wanganjie    时间: 2009-7-2 12:49

 

3、Linear clones created using the fixed-weighted method would be most appropriate for which of the following investors?

I.           Active investor implementing a dynamic asset-allocation policy.

II.         Passive investor with little expertise in trading.

A) I only.

B) Both I and II.

C) II only.

D) Neither I nor II.


作者: wanganjie    时间: 2009-7-2 12:49

 

The correct answer is C

More active investors engaging in dynamic asset-allocation will prefer the rolling-window method, and the more passive investors will prefer the fixed-weight approach.



作者: wanganjie    时间: 2009-7-2 12:49

 

4、Which of the following most accurately describes the liquidity of linear clones of hedge funds and the hedge funds that they are replicating?

I.           Positive first-order autocorrelation is an indicator of illiquidity risk.

II.         Hedge fund linear clones are less liquid than the hedge funds that they replicate.

III.        Larger p-values for the Ljung-Box Q-statistic indicate more statistically significant autocorrelation.

IV.      Larger p-values for the Ljung-Box Q-statistic indicate less statistically significant autocorrelation.

A) I and IV.

B) I, II and III.

C) II and III.

D) I and III.


作者: wanganjie    时间: 2009-7-2 12:49

 

The correct answer is A

Positive first-order autocorrelation indicates an illiquidity, and the larger p-values indicate less significant measures of autocorrelation (illiquidity).
