问题如下:

The broker suggests that Young rebalance her $5.5 million money market account and the $3.0 million tax-deferred retirement account periodically in order to maintain their targeted allocations. The broker proposes the same risk profile for the equity positions with two potential target equity allocations and rebalancing ranges for the two accounts as follows:
■ Alternative 1: 80% equities +/– 8.0% rebalancing range
■ Alternative 2: 75% equities +/– 10.7% rebalancing range

选项:

解释:

这道题我是从交易成本的角度答的,很好理解。

如果从波动率的角度,为什么波动越大,调整区间越窄,波动越小,调整区间越大?

从波动率的逻辑线解答下。

嗨,爱思考的PZer你好:


波动率越高,资产价格短期波动幅度越大,若设置较宽的再平衡区间,资产占比可能快速大幅偏离目标配置,导致组合风险显著超出预设水平。例如高波动率的股票资产,若允许较大偏离范围,股市短期大涨或大跌会使股票占比大幅超过或低于目标比例,破坏风险控制目标。

而波动率越低,资产价格波动越平稳,占比偏离目标的速度和幅度较小,较宽的再平衡区间既能减少频繁交易,又能在合理范围内维持配置稳定,避免因小幅波动触发交易,尤其适合税后账户考虑税收成本的场景,如税后账户波动率低于税前,通过放宽区间减少交易税负,这也是案例中 550 万美元税后账户适用更宽区间(Alternative 2)的原因。
