问题如下:

From the description of Sabonete’s objectives for the SPP, the most appropriate asset allocation approach is:

选项:

A.mean–variance optimization.

B.a basic two-portfolio approach.

C.an integrated asset–liability approach.

解释:

SoluC is correct. Based on the objectives described, the integrated asset–liability approach is the most appropriate asset allocation approach for the SPP, which is currently under-funded and seeks to achieve fully funded status in five years. Mean–variance optimization is an asset-only approach to asset allocation and fails to consider Sabonete’s goal of fully funding the liabilities. The basic two-portfolio approach assumes the pension plan has a surplus that can be allocated to a return-seeking portfolio.

C is correct. Based on the objectives described, the integrated asset–liability approach is the most appropriate asset allocation approach for the SPP, which is currently under-funded and seeks to achieve fully funded status in five years. Mean–variance optimization is an asset-only approach to asset allocation and fails to consider Sabonete’s goal of fully funding the liabilities. The basic two-portfolio approach assumes the pension plan has a surplus that can be allocated to a return-seeking portfolio.

A is incorrect. Mean–variance optimization is an asset-only approach to asset allocation and fails to consider Sabonete’s goal of fully funding the liabilities.

B is incorrect. The basic two-portfolio approach assumes the pension plan has a surplus that can be allocated to a return-seeking portfolio.

这题出的很严谨,B项说的是Basis two portfolio,如果是extend如partial/dynamic hedged才不要求必须cover liability。以前学到60%的程度可能擦边过,但现在需要向100%努力,100%没准儿才可以掌握80%,考场还要打折扣。

嗨,努力学习的PZer你好:


同学你好:


你的理解很正确,我们在备考的时候,对知识点的理解,一定尽全力达到100%,这样我们在真正考试的时候,才能得到80%的正确率,但是如果你平时就以掌握60%为目标,那到考试的时候,风险就会很大。


Hedging/Return-seeking 的方法,只有是最基础的模式时,必须要求是positive funded ratio,但是它还有两种变形,Partial hedge 和 Dynamic versions,并不要求positive funded ratio。也就是说,在如果想更加激进,或者打破这个局限,就引入了这两个变种策略.

这两个变种的策略,因为涉及Partial hedge,所以主要针对更加激进的Portfolio,所以这个策略对Underfunded会更好用一些,因为Underfunded时,这种策略可以加大Expected return,有机会补充缺口。这样即使没有surplus,基金经理也可以采用这些方法来更激进的投资,达到fully funded的目的。

但是这些variants 和 basic hedge/return seeking的方式,并不能混为一谈,在逻辑上它们的区别还是很大的。

Over the past severyears, the company’s growth strategy hcentereon expanng market share in emerging markets. Over half of revenues are from emerging markets, anthe remainr are from velopeEuropeeconomies. Oni Falana serves the chief investment officer of Sabonete’s finebenefit pension pl(SPP).

However, given the firm’s familiarity with anthe opportunities they perceive in emerging markets, the SPP hhistorically been over-weighte(25%) in this asset class. · 60% of company revenue is from sales in emerging markets, of whihalf is attributable to sales in AfricThe revenue growth rate for Sabonete’s Africbusiness is high but very volatile. The firm’s revenues anprofitability are quite sensitive to emerging markets.· The firm hsignificant investments in Africreestate. It recently acquireseverlarge parcels of lanin Afrifor €200 million anis planning to make a major investment in new manufacturing facilities to boost margins. Baseon these factors anthe information from Exhibit 1, Horvath presents the current asset allocation of the plalong with two other options for consiration (see Exhibit 2).Exhibit 2 Current anProposeAsset Allocation OptionsRecee Rall, analyst in SPP’s pension office, makes the following statements regarng Option 1: Horvath states, “Option 1 provis a 95% probability of meeting the goof reaching fully funstatus in five years, but interim contributions are likely to quite variable. Option 2 is likely to result in a more stable contribution rate but with a lower probability of meeting the funng goal.” Falana plans to recommenOption 2, believing ththe greater certainty of meeting the requireyear-to-yecontributions is the more important objective. She asks Rall to recommena rebalancing polifor Option 2. He proposes the ranges shown in Exhibit 3 anprovis estimate of the relatetransaction costs.Exhibit 3 Rebalancing Ranges for Option 2Rall justifies his recommention on the basis of the following statements:A wi rebalancing range for globfixeincome is appropriate because of its low volatility, low transaction costs, anlow correlation with other asset classes in the portfolio. The allocation for private equity is challenging because a low-cost passive investment vehicle es not exist anmoling with a private equity inx captures only the return aspects of private equity without appropriate representation of risk. Falana scusses the recommenasset allocation with the Pension Committee. A new committee member, James Alessano, states thhis preferenwoulOption 1 because the best pension fun have aptethe enwment mol of asset allocation, whiha higher allocation to alternative investments.
