idiosyncratic alpha请解释

NO.PZ2022062601000030

问题如下:

When investor John chose a hedge fund manager, he identified the following characteristics: low to moderate leverage, idiosyncratic alpha, long biased, and not worrying about investing in illiquid strategies. John's investment advisor Bourne recommends hedge funds for him.

Based on the characteristics determined by John, which hedge fund strategy is Bourne most likely to recommend?

选项:

A.

Managed futures

B.

Distressed securities

C.

Convertible bond arbitrage

解释:

B is correct. Bourne is looking for a hedge fund with the following characteristics: low to moderate leverage, idiosyncratic alpha, long biased, and not worried about liquidity. Of the strategies listed, the distressed securities strategy meets these desired characteristics most closely.

A is incorrect. Managed futures strategies typically contain a large amount of embedded leverage, which can be long or short biased and typically have liquidity.

C is incorrect. Convertible bond arbitrage strategies often use high levels of leverage and are net neutral.

知识点考察:event-driven strategies

Brownstein’s investment committee要求的HF的特点是low to moderate levels of leverage, idiosyncratic alpha, long biased, and no concerns about investing in an illiquid strategy.

A 不正确。Managed futures strategies通常包含大量嵌入式杠杆,可以偏多或偏空,并且通常具有流动性。


C 不正确。Convertible bond arbitrage经常使用高水平的杠杆并且是net neutral


B选项是正确的,the distressed securities strategy满足了Brownstein’s investment committee的所有要求。

如题,第一次见这个说法,请描述下ABC选项是否有,谢谢

嗨,努力学习的PZer你好:


“Idiosyncratic alpha”指的是投资组合中不能归因于市场回报的部分,是与市场无关且独立的回报来源。

在投资领域,alpha 被认为是投资组合回报超出市场基准回报的部分。而特质阿尔法则强调这种超额回报是来自于特定投资或投资策略的独特属性或特质。

特质阿尔法与特质风险(idiosyncratic risk)相关。特质风险是指来自于单个证券(或投资类别)的风险,其水平高度依赖于该证券自身的独特特征。通过自下而上的证券选择和自上而下的战略性资产配置产生的主动型特质阿尔法,通常与股票、债券和市场的相关性较低——只要阿尔法不存在额外的贝塔风险。它可以分散股票市场的风险,并同时达到两个目标:降低风险和提高业绩,即不仅可以作为回报的来源,还能作为风险的分散工具,使用它可以提高投资组合的风险调整后收益。

例如,一些主动型基金经理通过深入研究和分析个别公司的基本面,挑选出被低估或具有独特增长潜力的股票,从而获得特质阿尔法。或者通过采用特定的投资策略,如某些对冲基金策略,来获取与市场表现不太相关的超额回报。

所以理论上BC的投资产品都有的,A如果投资的很大类,可能是没有的,

我当时是在equity里学习的,如果这两年考纲没改的话,应该内容还在。

虽然现在很辛苦,但努力过的感觉真的很好,加油!
