讲义80页最后一句话什么意思

NO.PZ2021090805000022

问题如下:

John and his wealth advisor Bourne discuss investments.

Bourne described the differences between deterministic predictions and Monte Carlo simulations in investment plans and traditional and goal-based methods in constructing investment portfolios. After hearing about these methods, John stated that he believes that goal-based investment methods are most suitable for his needs because

  • it allows him to specify a level of risk tolerance for each goal,

  • growth toward each goal on a straight-line basis is much easier to understand, and

  • It provides the ability to predict the success probability of each goal.

John's most appropriate comment on his preference for goal-based investment methods is:

选项:

A.

risk tolerance.

B.

growth toward a goal.

C.

probability of success of a goal.

解释:

A is correct. Only the comments on risk tolerance specifically addresses goal-based investments, and his statement is correct.

B is incorrect. Straight-line growth is not a feature of goal-based investing; it is a component of the deterministic forecasting method for determining capital sufficiency in which a given return is assumed to compound until the investment horizon is reached.

C is incorrect. Probability of success is not a feature of goal-based investing; it is an outcome of the Monte Carlo method for determining capital sufficiency.

A是正确的。只有关于风险承受能力的评论专门针对基于目标的投资,他的说法是正确的。

B不正确。直线增长不是基于目标的投资的特征;它是确定资本充足性的确定性预测方法的一个组成部分,在该方法中,假设给定的回报率是复合的,直到达到投资期限。

C不正确。成功的概率不是基于目标的投资的特征;它是确定资本充足性的蒙特卡罗方法的结果。

能详细说说吗?还是不太明白是什么意思

在Goal based investment appraoch这个方法下,我们会对投资者的目标进行分层,那么每层都会有一个目标,针对每层的目标我们会制定一个投资组合去完成,那么每层的投资组合会被规定一个客户能够接受的最大的风险水平或者成功概率,然后进行投资

您说的是这句话吗,讲义80页最后一句:

在Goal based investment appraoch中,每个goal里的投资组合会被优化到规定的最大波动水平或指定的成功概率

即在每一个goal内使用mean-variance optimization,可以在投资者可接受范围内挑一个最大风险的allocation以便于获得最大化的收益去实现投资者的目标
