这个问题为何B不对?

NO.PZ2024010508000019

问题如下:

A portfolio manager is creating a bond fund with an ESG tilt. In constructing the portfolio, the manager will:

选项:

A.be limited to short-term maturities to avoid climate risk. B.be able to select green bonds based on a universally accepted ranking system. C.have a smaller investable universe to select from for sovereign bonds compared to corporate bonds.

解释:

C is correct. An ESG-tilted portfolio could hold both corporate and sovereign debt, but the investable universe for sovereign debt is much smaller than the number of corporates that issue corporate debt. While sovereign debt outstanding in money terms is exceptionally large, the number of sovereign issuers is far lower than the number of corporate issuers. There is not currently a universally accepted ranking system for green bonds. If the manager is concerned about a particular issuer’s ability to manage climate risk, the manager might limit the investment in that issuer’s debt to shorter maturities, but that would not apply to all bonds in the portfolio.

投资经理想要ESG偏向的债券,不应该直接在市场里面选择绿色债券即可么?

我知道C的表述是正确的,但为何是这题的最终选项?主权债券是更加保险的投资标的,但不是要契合ESG的题目述求么?主权债券虽然发行要求严格,但并不是所有主权债券都是有明确ESG表述及达成述求的吧

嗨,爱思考的PZer你好:


构建具有ESG倾向的债券基金时,投资经理可能会面临以下几个关键因素的考量:

  • 短期与长期债券的选择
  • 选项A:这暗示了投资经理为了避免气候风险,可能会倾向于短期债券。虽然气候风险确实是重要考量,但这并不意味着所有债券都需要限制在短期范围内。
  • 绿色债券的选择
  • 选项B:虽然绿色债券是与ESG直接相关的债券类型,但目前市场上还没有一个普遍接受的绿色债券评级系统。这使得绿色债券的选择和评估变得复杂。因此,选项B并不是最合适的回答。具体分析下方
  • 主权债券与公司债券的投资范围
  • 选项C:这个选项指出了主权债券的数量有限,而公司债券发行者的数量相对更多。这使得投资经理在选择主权债券时的投资范围更小,特别是在追求ESG标准的情况下。这种限制使得选项C成为最合适的回答,因为它直接反映了实际投资过程中面临的约束。

解释为何选项C是正确的:

在构建具有ESG倾向的债券基金时,投资经理不仅需要考虑债券的ESG特性,还需要考虑市场上可供选择的债券数量和种类。尽管主权债券可能被认为更安全,但在追求ESG投资时,可供选择的主权债券数量较少,这是因为:

  1. 主权债券发行者数量有限:市场上主权债券的发行者相对较少,而公司债券的发行者数量更多,这提供了更大的选择余地。
  2. ESG标准的实施差异:并不是所有的主权债券都明确满足ESG标准,这进一步缩小了可选择的范围。
  3. 投资组合多样化:为了实现投资组合的多样化并满足ESG标准,经理可能会更多地选择公司债券,因为这些债券在市场上数量更多、种类更丰富。

综上所述,选项C被认为是最准确的回答,因为它反映了在实际投资过程中,投资经理在构建ESG偏向的债券基金时,所面临的实际投资范围和选择上的限制。


选项 B 投资经理可以根据一个普遍接受的评级系统选择绿色债券。

  1. 目前缺乏普遍接受的绿色债券评级系统
  • 虽然有一些机构(如气候债券倡议组织(Climate Bonds Initiative)等)提供绿色债券认证和评级,但这些评级系统尚未在全球范围内得到广泛的普遍接受。
  • 绿色债券市场仍在发展,各评级机构使用的标准和方法可能存在显著差异。这导致市场缺乏一致性和透明度。
  1. 评级系统的不一致性
  • 不同的评级机构可能会对同一债券的绿色属性进行不同的评价。这使得基金经理难以依赖单一的、普遍接受的评级系统来选择绿色债券。
  1. 绿色债券数量有限
  • 尽管绿色债券市场在增长,但其规模仍然较小,不能完全满足所有投资组合的需要。投资经理可能需要结合其他类型的债券来构建一个具有ESG倾向的多元化投资组合。

即使选项 B 中提到的绿色债券评级系统在未来变得更加成熟和普遍接受,投资经理在选择债券时仍需考虑其他因素,如流动性、信用风险、市场条件等。因此,选项 B 并不能完全解决投资经理在构建 ESG 倾向债券基金时面临的所有问题。
