学员你好,
M^2 focuses on total volatility as a measure of risk, but its risk adjustment leads to an easy-to-interpret differential return relative to the benchmark index.
这是说M^2这个指标用来衡量波动率,但是更加容易理解(如果投资组合的总风险和市场组合一样,那么会额外产生的回报)。
The return for the perfect timer in each year is the average of the return on stocks and the return on bills. 完美的择时指的是最终的收益是股票和债券收益的平均数,这个不对,应该是熟大值。
Market timing involves shifting funds between a market-index portfolio and a safe asset, depending on whether the market index is expected to outperform the safe asset.
这个说法就正确了,完全是择时的定义。
Managers can manipulate their performance measures by adjusting their risk-return profile in response to performance in the early part of an evaluation period.
可以操作的,如果投资完成之后再修改基准,然后找一个差的基准的话就可以使得投资的表现更好一些。
